New Dumas Protein Analyzer at the Sample Control Laboratory
The Sample Control Laboratory has further enhanced its analytical capabilities with the acquisition of a new instrument for protein determination using the Dumas method.
Applications of this modern analytical equipment enables even faster, more accurate, and more efficient protein analysis in various types of samples, primarily food products.
What is the Dumas Method?
The Dumas method is a modern instrumental technique used to determine total nitrogen content, which is then used to calculate the protein content of a sample.
The method is based on:
combustion of the sample at high temperatures
determination of the released nitrogen
automatic data processing and result calculation
Compared to traditional protein determination methods, the Dumas method offers:
shorter analysis time
high precision and repeatability
a fully automated process
no use of aggressive chemicals
Due to its efficiency and reliability, the method is widely accepted in modern food quality control laboratories.
Applications of Protein Analysis
Protein analysis is an important parameter in assessing the quality and nutritional value of products.
It is most commonly performed for:
food products
animal feed
cereals and milling products
protein-based food supplements
raw materials and intermediate products
The results are used for nutritional labeling, quality control, and compliance with regulatory requirements.
Continuous Investment in Laboratory Equipment
The acquisition of the new instrument is part of Sample Control Laboratory’s ongoing investment in modern laboratory equipment and the development of analytical methods.
The objective of these investments is to ensure:
high-quality and reliable results
faster sample turnaround times
increased laboratory capacity
alignment with the latest trends in analytical testing
By implementing advanced technologies, Sample Control Laboratory continues to provide professional and high-quality support to the food industry and other clients.

Sample Control laboratory has expanded its service portfolio and has started conducting challenge tests for the bacterium Listeria monocytogenes in food products.
PPWR – Regulation (EU) 2025/40 and the New Requirements for Packaging
The European Union has adopted Regulation (EU) 2025/40 on packaging and packaging waste (PPWR), representing one of the most significant regulatory changes in the field of packaging in recent years. Unlike the previous directive, this regulation is directly applicable in all EU Member States, with most of its provisions becoming applicable from 12 August 2026.
