<h3>Molecular testing</h3>In its work, the laboratory applies state-of-the-art molecular and serological procedures of identification and typification.PCR (Polymerase chain reaction)Real-time PCR polymerase chain reaction is a process in which we process a wide range of samples, since in just a few hours one single copy of a specific segment (sequence) of DNA will multiply into trillions of identical copies (molecules). It is highly sensitive, specific and reliable because there is less risk of contamination of samples, and an automatic reaction performance can search for a large number of samples.We perform high-quality testing services of the following:<ul><li><a target="_self" rel="noopener noreferrer nofollow" href="https://www.sample-control.hr/en/services/food-and-feed-testing?s=food-allergens">allergens</a></li></ul><ul><li><a target="_self" rel="noopener noreferrer nofollow" href="https://www.sample-control.hr/en/services/food-and-feed-testing?s=gmo-analyses">genetically modified organisms (GMO analysis)</a></li><li><a target="_self" rel="noopener noreferrer nofollow" href="https://www.sample-control.hr/en/services/food-and-feed-testing?s=dna-analyses-authenticity-testing">DNA analysis - authenticity testing and animal species identification</a></li><li>bacteria (Salmonella serovar Typhimurium and Salmonella serovar Enteritidis)</li><li>viruses (norovirus, hepatitis A)</li></ul>ELISA (Enzyme Linked Immunosorbent Assay)Immunoenzyme test (ELISA) is an antibody-based method.

The reaction is based on binding antibodies and antigens from the sample, and spectrophotometric measurement of the resulting reaction, which occurs due to discoloration. This highly sensitive and selective method can determine a very low concentration of analytes of, for example, several ng per kg of the test sample. The tests are commercially available in many forms and have a number of applications within the framework of quality control and food safety.The corresponding values of validation parameters, such as sensitivity, specificity and detection limit, make ELISA tests suitable and frequent for the determination of allergens in food.

Molecular testing

<h3>Microplastics testing</h3>In everyday life, people use plastic that is mostly non-biodegradable. Over time, through various processes, plastic breaks down into smaller particles. Particles with a diameter ranging from 1 µm to 5 mm are referred to as microplastics. Recent studies have shown that microplastics can be found in food, especially seafood. As plastic is present in marine environments, fish and other marine organisms ingest it. Studies have revealed that some fish species replace food with plastic, leading to the accumulation of toxic chemicals in their livers. Further research has found that shellfish and oysters, raised for human consumption, contain 0.36-0.47 microplastic particles per gram, meaning consumers could ingest up to 11,000 microplastic particles annually.&nbsp;Experts estimate that humans ingest between 74,000 and 121,000 microplastic particles per year through eating and inhalation. A systematic review published in 2022 highlighted cytotoxicity, immune response, and oxidative stress as negative health consequences associated with microplastics. It was also noted that cell viability decreased at 10 µg/mL of particles sized 5-200 µm. Another study in 2022 detected microplastics in human blood at a concentration of 1.6 µg/mL. Moreover, plastics often contain additives such as stabilizers and flame-resistant compounds, along with other potentially toxic chemicals that can be harmful to both animals and humans.&nbsp;Given the varying toxicity levels of plastic materials, accurate characterization is crucial. Microplastic identification is carried out using spectroscopic techniques such as FT-IR (Fourier-transform infrared spectroscopy) and Raman microscopy/spectroscopy, as well as pyrolytic gas chromatography coupled with mass spectrometry (Py-GC-MS).&nbsp;Raman spectroscopy and FT-IR microscopy are proven effective instrumental techniques for the qualitative and quantitative determination of microplastics. Both Raman microscopy and FT-IR microscopy are vibrational spectroscopic techniques based on the interaction of incoming light with the molecules of a sample. In Raman spectroscopy, this interaction leads to inelastic scattering and a change in the frequency of the incoming light, while FT-IR spectroscopy results in the absorption of specific frequencies of the incoming light. The interaction generates a Raman or FT-IR spectrum specific to that molecule, which is ultimately used for identification. Adding optical microscopy to these techniques allows for the localization, quantification, and identification of microplastic particles.&nbsp;Sample Control laboratory utilizes the DXR3xi Raman Imaging microscope and LUMOS II FT-IR microscope to offer clients comprehensive microplastic analysis in products through Raman or FT-IR microscopy. These analyses provide information on the distribution, quantity, size, and type of polymer micro-particles.&nbsp;The laboratory currently has developed methods for microplastic testing in:&nbsp;Drinking water and seawaterNon-alcoholic and alcoholic beveragesFood and dietary supplementsCosmeticsFood and cosmetic packagingSoil and sediments

<h4>Testing Microplastics in Food</h4>The main routes of microplastic intake into the human body are inhalation, food, and drinking water. Microplastic particles can have various destructive effects within the human body. For instance, harmful effects may arise from undesirable additives or toxic substances present within the particles or adsorbed onto their surfaces (e.g., phthalates, BPA, PBDE, pesticides, heavy metals, PAHs, etc.), from tissue damage caused by the intake of microplastic particles into cells, or from the harmful effects of pathogenic microorganisms adsorbed onto the surface of microplastic particles. A 2019 study estimated that children, women, and men within the U.S. population ingest between 74,000 to 113,000 microplastic particles annually through inhalation, food, and beverages. Given the potential harmful effects of microplastics within the body, particularly concerning are the findings from studies that have detected microplastic particles in the lungs, blood, and breast milk.The identification of the type, size, and quantity of microplastic particles is effectively conducted using microspectroscopic techniques such as FTIR (Fourier-transform infrared spectroscopy) and Raman microscopy/spectroscopy. After successfully accrediting the method for analyzing microplastics in water samples in 2021, Sample Control developed and accredited a method for determining microplastics in food samples using Raman microscopy in 2022, utilizing the DXR3xi Raman Imaging microscope. To enhance the range of capabilities and speed of microplastic analyses, a LUMOS II FTIR microscope was acquired in 2024. With these two devices, Sample Control can offer its clients extensive analysis of microplastics in food samples.

<h4>Ispitivanje mikroplastike u hrani</h4>Glavni putevi unosa mikroplastike u ljudski organizam su udisanje, prehrana i voda za piće. Čestice mikroplastike mogu imati različite vrste destruktivnih učinaka unutar ljudskog organizma. Primjerice, moguće je štetno djelovanje putem nepoželjnog djelovanja aditiva ili toksičnih supstanci prisutnih unutar čestica ili adsorbiranih na površini čestica mikroplastike (npr. ftalati, BPA, PBDE, pesticidi, teški metali, PAH-ovi, ...), zatim putem oštećenja tkiva uzrokovanog prilikom unosa čestica mikroplastike u stanice ili putem štetnog djelovanja patogenih mikroorganizama adsorbiranih na površinu čestica mikroplastike. Istraživanje iz 2019. godine, procijenilo je kako djeca, žene i muškarci unutar američke populacije, tijekom jedne godine, putem udisanja, hrane i pića, u organizam unesu 74 000 do 113 000 čestica mikroplastike. S obzirom na potencijalne štetne učinke mikroplastike unutar organizma, posebice zabrinjavaju rezultati studija koje su dokazale prisutnost čestica mikroplastike unutar pluća, krvi i mlijeka dojilja.Određivanje vrste, veličine i količine čestica mikroplastike se učinkovito provodi pomoću mikrospektroskopskih tehnika kao što su FTIR (engl. Fourier-transform infrared spectroscopy) i Raman mikroskopija/spektroskopija.Nakon uspješne akreditacije metode za analizu mikroplastike u uzorcima vode 2021. godine, laboratorij Sample Control 2022. je godine razvio i akreditirao metodu za određivanje mikroplastike u uzorcima hrane primjenom Raman mikroskopije, za što je korišten DXR3xi Raman Imaging mikroskop. Kako bi se unaprijedili raspon mogućnosti i brzina analiza mikroplastike, 2024. godine nabavljen je LUMOS II FTIR mikroskop. Uz ova dva uređaja, Sample Control može svojim klijentima ponuditi opsežnu analizu mikroplastike u uzorcima hrane.

<h4>Testing Microplastics in Water</h4>Different types of water bodies, including marine sources, freshwater sources, wastewater, and drinking water, contain varying amounts of microplastics, with drinking water being the most significant immediate source of microplastics. A 2019 study estimated that children, women, and men in the U.S. population ingest between 64,000 to 127,000 microplastic particles through bottled water or tap water annually, with figures ranging from 3,000 to 6,000 particles per person. The presence of microplastics in marine and freshwater sources also poses a problem due to their direct impact on animal organisms and indirect impact on humans through the food chain. Numerous studies have shown that marine organisms can ingest microplastics, often with serious consequences, as they can accumulate in tissues, act as vectors for infections, and absorb and transfer hazardous chemicals.Identifying sources of pollution is challenging because microplastics in water typically come from various sources, at different locations and times. To propose possible solutions for reducing the intake of microplastics into aquatic environments, it is essential to identify primary sources as well as the type of microplastic materials, making accurate material characterization crucial. The determination of the type, size, and quantity of microplastic particles is effectively carried out using vibrational spectroscopic techniques such as Raman and infrared (IR) spectroscopy.Sample Control Laboratory recognized the need for routine microplastic analysis early on. In 2020, we acquired the DXR3xi Raman Imaging microscope, and the following year, we became the first in Croatia to accredit a method for analyzing microplastics in drinking water and seawater. Since then, the laboratory has gained extensive experience in analyzing various types of water samples, including wastewater, environmental water samples from rivers and lakes, and even water sourced from Antarctic ice. To enhance the range of capabilities and speed of microplastic analyses, a LUMOS II FTIR microscope was acquired in 2024. With these two devices, Sample Control can offer its clients comprehensive analysis of microplastics in various types of water samples.

<h4>Ispitivanje mikroplastike u vodi</h4>&nbsp;Različite vrste tijela vode, uključujući morske izvore, slatkovodne izvore, otpadne vode i vodu za ljudsku potrošnju, sadrže različite količine mikroplastike, pri čemu je voda za ljudsku potrošnju najvažniji neposredni izvor mikroplastike. Istraživanje iz 2019. godine, procijenilo je kako djeca, žene i muškarci unutar američke populacije, tijekom jedne godine, putem flaširane vode ili vode iz slavine, u organizam unesu 64 000 – 127 000, odnosno 3000 – 6000 čestica mikroplastike. Prisutnost mikroplastike u izvorima morske i slatke vode također predstavlja problem zbog njihovog neposrednog utjecaja na životinjske organizme i posrednog utjecaja na ljudski organizam putem prehrane. Brojne studije pokazale su da morski organizmi mogu progutati mikroplastiku, često s ozbiljnim posljedicama, budući da se ona može nakupiti u tkivima, djelovati kao prijenosnik infekcija te apsorbirati i prenositi opasne kemikalije.Pronalazak izvora onečišćenja otežan je, zato što mikroplastika koja završi u vodi obično dolazi iz različitih izvora, s različitih lokacija i u različitim vremenskim razdobljima. Kako bi se predložila moguća rješenja za smanjenje unosa mikroplastike u vodeni okoliš, potrebno je odrediti prvotne izvore, kao i vrstu materijala mikroplastike, za što je važna točna karakterizacija materijala. Određivanje vrste, veličine i količine čestica mikroplastike se učinkovito provodi pomoću vibracijskih spektroskopskih tehnika poput Raman i infracrvene (IR) spektroskopijeLaboratorij tvrtke Sample Control rano je prepoznao potrebu za provođenjem rutinskih analiza mikroplastike. 2020. godine nabavljen je DXR3xi Raman Imaging mikroskop , a sljedeće je godine prvi u Hrvatskoj akreditirao metodu za analizu mikroplastike u vodi za ljudsku potrošnju i morskoj vodi. Od tada pa sve do danas, laboratorij je stekao ogromno iskustvo u analizi različitih vrsta uzoraka vode, poput vode iz uređaja za pročišćavanje, okolišnih uzoraka vode poput riječnih i jezerskih voda te čak i voda porijeklom iz leda s Antarktike. Kako bi se unaprijedili raspon mogućnosti i brzina analiza mikroplastike, 2024. godine nabavljen je LUMOS II FTIR mikroskop (Bruker). Uz ova dva uređaja, Sample Control može svojim klijentima ponuditi opsežnu analizu mikroplastike u različitim vrstama uzoraka vode.

<h4>Testing Microplastics in Cosmetics</h4>Synthetic polymers, due to their beneficial properties, are used in nearly all areas of human activity. However, plastic products often end up in the environment, where they fragment into smaller, insoluble particles through physical and chemical processes. In 2023, the European Commission adopted <a target="" rel="noopener noreferrer nofollow" href="https://eur-lex.europa.eu/eli/reg/2023/2055/oj">Regulation 2023/2055</a>, which restricts the addition of microplastics to products, aiming to reduce their release into the environment by 30% by 2030. Among the products included in this restriction are cosmetics, where microplastics are used for multiple purposes, such as exfoliation (microbeads) or achieving specific textures, scents, or colors.The identification of the type, size, and quantity of microplastic particles is effectively conducted using microspectroscopic techniques such as FTIR (Fourier-transform infrared spectroscopy) and Raman microscopy/spectroscopy. After successfully accrediting methods for analyzing microplastics in water and food samples in 2021 and 2022, respectively, Sample Control developed and accredited a method for determining microplastics in cosmetic samples using Raman microscopy in 2023, utilizing the DXR3xi Raman Imaging microscope. To enhance the range of capabilities and speed of microplastic analyses, a LUMOS II FTIR microscope was acquired in 2024. With these two devices, Sample Control can offer its clients extensive analysis of microplastics in cosmetic samples.

<h4>Ispitivanje mikroplastike u kozmetici</h4>&nbsp;Sintetički polimeri, zbog svojih korisnih svojstava, koriste se u gotovo svim područjima ljudske djelatnosti. Međutim, plastični proizvodi često završavaju u okolišu, gdje se putem fizičkih i kemijskih procesa fragmentiraju u manje, netopive čestice. U 2023. godini Europska komisija usvojila je <a target="" rel="noopener noreferrer nofollow" href="https://eur-lex.europa.eu/eli/reg/2023/2055/oj">Uredbu 2023/2055</a> koja ograničava dodavanje mikroplastike u proizvode, s ciljem smanjenja njenog otpuštanja u okoliš za 30% do 2030. godine. Kao primjer nekih od proizvoda u opsegu ograničenja navode se i kozmetički proizvodi, gdje se mikroplastika koristi za višestruke svrhe, kao što je piling (mikrozrnca) ili dobivanje specifične teksture, mirisa ili boje.Određivanje vrste, veličine i količine čestica mikroplastike se učinkovito provodi pomoću mikrospektroskopskih tehnika kao što su FTIR (engl. Fourier-transform infrared spectroscopy) i Raman mikroskopija/spektroskopija.Nakon uspješne akreditacije metode za analizu mikroplastike u uzorcima vode i hrane 2021., odnosno 2022. godine, laboratorij Sample Control 2023. je godine razvio i akreditirao metodu za određivanje mikroplastike u uzorcima kozmetike primjenom Raman mikroskopije, za što je korišten DXR3xi Raman Imaging mikroskop. Kako bi se unaprijedili raspon mogućnosti i brzina analiza mikroplastike, 2024. godine nabavljen je LUMOS II FTIR mikroskop. Uz ova dva uređaja, Sample Control može svojim klijentima ponuditi opsežnu analizu mikroplastike u uzorcima kozmetike.

<h3>Ispitivanje mikroplastike</h3>U svakodnevnom životu ljudi koriste plastiku koja, uglavnom, nije razgradiva. Tijekom vremena, putem različitih vrsta procesa, plastika se raspada na manje čestice. Pritom se one čestice promjera u rasponu od 1 µm do 5 mm nazivaju mikroplastikom. Nedavne studije pokazale su da mikroplastiku nalazimo u hrani, osobito onoj koja dolazi iz mora. Kako je plastika uobičajena u morskoj vodi, konzumiraju je ribe i drugi morski organizmi. Nedavne studije našle su da neke vrste riba zamjenjuju plastiku hranom pa se toksične kemikalije akumuliraju unutar jetre ribe. Daljnje studije utvrdile su da školjke i oštrige, uzgajane za ljudsku prehranu, imaju 0.36-0.47 čestica mikroplastike po gramu pa konzumenti te hrane mogu progutati do 11.000 čestica mikroplastike godišnje.Stručnjaci procjenjuju da ljudi godišnje, gutanjem i udisanjem, unose mikroplastiku u rasponu od 74.000 do 121.000 čestica. U sustavnom preglednom članku objavljenom 2022. godine navode se citotoksičnost, imunosni odgovor, oksidativni stres kao neki od negativnih posljedica za ljudsko zdravlje povezanih s mikroplastikom, a utvrđena je i smanjena vijabilnost stanica pri 10 µg/mL čestica veličine 5-200 µm. Drugo istraživanje objavljeno 2022. godine pokazalo je kako se čak u ljudskoj krvi može pronaći mikroplastika u koncentraciji od 1.6 µg/mL. Nadalje, plastika često sadrži dodatke kao što su stabilizatori i spojevi otporni na plamen te ostale potencijalno toksične kemijske spojeve koji mogu biti štetni za životinje i ljude.Budući da plastični materijali imaju različitu razinu toksičnosti, vrlo je važna točna karakterizacija materijala. Identifikacija mikroplastike se provodi pomoću spektroskopskih tehnika kao što su FT-IR (engl. Fourier-transform infrared spectroscopy) i Raman mikroskopija/spektroskopija te pirolitičko plinska kromatografija sa spektrometrijom masa (Py-GC-MS).<a target="_self" rel="noopener noreferrer nofollow" href="https://www.sample-control.hr/usluge/raman-spektroskopija-i-mikroskopija">Ramanova spektroskopija </a>i FT-IR mikroskopija dokazane su i učinkovite instrumentalne tehnike za kvalitativno i kvantitativno određivanje mikroplastike.<a target="_self" rel="noopener noreferrer nofollow" href="https://www.sample-control.hr/usluge/raman-spektroskopija-i-mikroskopija">Ramanova mikroskopija</a> i FT-IR mikroskopija su vibracijske spektroskopske tehnike koje se temelje na interakciji ulazne svjetlosti i molekula uzorka. U slučaju Raman spektroskopije, ova interakcija uzrokuje neelastično raspršenje i promjenu frekvencije ulazne svjetlosti, dok u slučaju FT-IR spektroskopije ona uzrokuje apsorpciju ulazne svjetlosti određenih frekvencija. U obje se tehnike kao rezultat interakcije ulazne svjetlosti i molekule uzorka dobiva Raman, odnosno FT-IR spektar specifičan za tu molekulu, što se u konačnici koristi za njenu identifikaciju. Dodavanje začajke optičke mikroskopije ovim dvjema tehnikama daje mogućnost lociranja, kvantificiranja i identifikacije čestica mikroplastike.Laboratorij Sample Control pomoću DXR3xi Raman Imaging mikroskopa i LUMOS II FT-IR mikroskopa može svojim klijentima ponuditi opsežnu analizu mikroplastike u proizvodima putem Raman ili FT-IR mikroskopije. Ovim analizama dobivaju se informacije o distribuciji, broju, veličini i vrsti polimernih mikročestica.U laboratoriju trenutno imamo razvijene metode za ispitivanje mikroplastike u:<ul><li>vodi za ljudsku potrošnju i morskoj vodi,</li><li>bezalkoholnim i alkoholnim pićima,</li><li>hrani i dodacima prehrani,</li><li>kozmetici,</li><li>ambalaži za hranu i kozmetiku</li><li>zemlji i sedimentima</li></ul>

<h3>Preiskovanje mikroplastike</h3>V vsakdanjem življenju ljudje uporabljajo plastiko, ki v glavnem ni razkrojljiva. S potekom časa, zaradi različnih vrst procesov, plastika se razpada na manjše delce. Pri tem tistim delcem, ki imajo premer od 1 µm do 5 mm, rečemo mikroplastika. Nedavne študije so pokazale, da mikroplastiko najdemo v hrani, zlasti tisti ki prihaja iz morja. Ker je plastika običajna v morski vodi, jo konzumirajo ribe in drugi morski organizmi. Nedavne študije so pokazale, da nekatere vrste rib zamenjajo plastiko za hrano ter se &nbsp;toksične kemikalije akumulirajo znotraj ribjih jeter. Nadaljnje študije so ugotovile, da školjke in oštrige, vzrejene za človeško prehrano, imajo 0.36-0.47 delcev mikroplastike po gramu ter konzumenti te hrane lahko zaužijejo do 11.000 delcev mikroplastike na leto.Strokovnjaki ocenjujejo, da ljudje na leto s požiranjem ali vdihavanjem vnašajo mikroplastiko v količini od 74.000 do 121.000 delcev. V sistematičnem preglednem prispevku objavljenem leta 2022 je navedena citotoksičnost, imunski odziv, oksidativni stres kot nekatere med negativnimi posledicami za človeško zdravje povezanih z mikroplastiko, ugotovljena pa je tudi zmanjšana viabilnost celic pri 10 µg/mL delcev velikih 5-200 µm. Drugo raziskovanje, objavljeno leta 2022, je pokazalo da celo v človeški krvi lahko najdemo mikroplastiko v koncentraciji 1.6 µg/mL. Nadalje, plastika pogosto vsebuje dodatke, kot so stabilizatorji in spojine odporne na ogenj, ter ostale potencialno toksične kemijske spojine, ki so lahko škodljive za živali in ljudi.Ker plastični materiali imajo različno raven toksičnosti, je zelo pomembna točna karakterizacija materiala. Identifikacijo9 mikroplastike opravljamo s pomočjo spektroskopskih tehnik kot so FT-IR (angl. Fourier-transform infrared spectroscopy) in Raman mikroskopija/spektroskopija ter pirolitično plinsko kromatografijo s spektrometrijo mas (Py-GC-MS).<a target="_self" rel="noopener noreferrer nofollow" href="https://www.sample-control.hr/sl/storitve/raman-spektroskopija-in-mikroskopija">Ramanova spektroskopija</a> je dokazano in učinkovito sredstvo za identificiranje mikroplastike.<a target="_self" rel="noopener noreferrer nofollow" href="https://www.sample-control.hr/sl/storitve/raman-spektroskopija-in-mikroskopija">Ramanova mikroskopija</a> kombinira Ramanovo spektroskopijo in optično mikroskopijo in je eden izmed najbolj učinkovitih načinov za identificiranje polimerjev. S to tehniko lahko lociramo in identificiramo delce s premerom do 1 µm. Nadalje, če mikroplastika vsebuje zmes komponent, Raman spektroskopija lahko kemično identificira polimer kot tudi vse aditive, vključno s pigmenti. Enkrat ko so molekule identificirane, določitev vira in toksičnosti postane lažja, to pa potem lahko pripelje do strategije zmanjšanja onesnaženosti.Laboratorij Sample Control putem DXR3xi Raman Imaging mikroskopa svojim klientom lahko ponudi obsežno analizo mikroplastike v izdelkih, ki vključuje določanje distribucije števila, velikosti in vrst polimernih mikrodelcev.V laboratoriju trenutno imamo razvite metode za preiskovanje mikroplastike v:<ul><li>vodi za človeško uporabo in morski vodi,</li><li>brezalkoholnih in alkoholnih pijačah,</li><li>hrani in dodatkom prehrani,</li><li>kozmetiki,</li><li>embalaži za hrano in kozmetiko.</li></ul>
