Chemical and toxicological department

Main areas of work:

• Studies of food products and raw materials on indicators of quality, safety and identification in order to confirm compliance of food products with the requirements of legislative and regulatory-technical documentation;
• Physical and chemical analysis of feeds, compound feeds, formula-feed raw materials;
• Hydrochemical analysis
• Determination of safety indicators of soil, mineral and organic fertilizers.
• Diagnosis of animal poisoning

The following facilities are tested in the Chemical and toxicological Department:

• food products;
• food raw materials;
• feeds;
• alcoholic beverages;
• environmental facilities;
• bio-/pathmaterial.

Assessment of safety indicators includes:

• toxic elements;
• pesticides of various chemical nature;
• mycotoxins;;
• hormonal substances;
• residual content of antibacterial, medicinal veterinary preparations;
• nitrates, nitrites;
• benzopyrene;;
• nitrosamines;
• other safety indicators in accordance with regulatory documents.

Evaluation of quality indicators includes:

• determination of moisture, fat, protein, salt, sucrose, ash, acidity, peroxide number, heat resistance, viscosity, density, etc. in products;
• determination of sugar content in sugar beets;
• determination of fatty acid composition, sterols in milk and dairy products.

To perform the research, the Department has modern high-tech equipment:

• The liquid mass spectrometer with a triple quadruple API 5000 (AB Sciex);
• The liquid mass spectrometer with a triple quadruple QTRAP 6500 (AB Sciex);
• The liquid mass spectrometer with a triple quadruple EVOQ Elite (Bruker);
• The highly efficient combined quadruple-time-of-flight mass spectrometer maXis Impact (Bruker);
• The mass spectrometer with inductively coupled plasma Aurora M90 (Bruker);
• The atomic absorption spectrometers series iCE 3000- Models: iCE 3300, iCE 3400, iCE 3500 (Thermo Fischer Scientific);
• The gas chromatograph SCION 456-GC (Bruker);
• The gas chromatograph "Crystal 2000М" (Chromatec);
• The liquid chromatograph with fluorimetric and diode-matrix detectors Agilent 1200 (Agilent);
• The laboratory microwave systems and others.

In 2012, the Department received international accreditation in the DANAK system, which is confirmed and expanded annually; that fact indicates a high level of the laboratory, competence of specialists and reliability of the applied analytical methods.
