Gas chromatograph Neochrom-FAT for the analysis of fats and oils

Chromatographic system Neochrom-FAT designed for complex gas chromatographic research of fats, vegetable oils, milk fat and fat-containing food products.

The complex allows you to determine the fatty acid composition, including cis- and trans-isomers of fatty acids, erucic acid, to study the sterol and triglyceride composition, to determine cholesterol, phytosterols and, depending on the configuration, waxes.

Comprehensive analysis of fatty acid, sterol and triglyceride profiles allows to identify the type of fatty raw material, control its authenticity and detect impurities of extraneous fats, in particular vegetable fats in milk fat and dairy products.

Analytical capabilities of Neochrom-FAT

1. Determination of fatty acid composition
   • gas chromatographic analysis of fatty acid methyl esters according to ISO 12966, GOST 31663 and GOST 31665;
   • determination of saturated, monounsaturated and polyunsaturated fatty acids;
   • determination cis- and trans-isomers of fatty acids according to ISO 12966-4 and GOST 31754;
   • determination of erucic acid and other individual fatty acids in the fatty acid profile.
2. Sterol composition
   • determination of individual and total sterols according to ISO 12228-1 and GOST ISO 12228-1;
   • determination of cholesterol and phytosterols — campesterol, stigmasterol, β-sitosterol and other components of the sterol fraction;
   • study of the sterol composition of milk fat according to ISO 12078, ISO 18252 and GOST ISO 18252;
   • detection of vegetable fat in milk and milk products by sterol profile according to GOST 31979.
3. Triglyceride composition
   • gas chromatographic analysis of triacylglycerols according to ISO/TS 17383 and GOST ISO/TS 17383;
   • determination of authenticity of milk fat and detection of extraneous fats by triglyceride profile according to ISO 17678 and GOST ISO 17678.
4. Detection of falsification of fats and oils
   • detection of vegetable fat impurities in milk fat, butter, cheese, sour cream and other dairy products;
   • identification of extraneous fats based on the combination of fatty acid, sterol and triglyceride profiles;
   • control of the authenticity of vegetable oils and products with a mixed composition of the fat phase, including for GOST 30623.
5. Determination of waxes

   With the appropriate configuration, the complex can be used for gas chromatographic determination of waxes. For olive and olive pomace oil — according to ISO 12873.

Milk fat authenticity testing

The use of two independent chromatographic approaches — analysis sterol profile and triglyceride profile — allows to increase the reliability of detection of extraneous fats in dairy products.

The complex can be used for the study of milk, butter, cream, sour cream, cheeses and other products, the fat phase of which is subject to control for authenticity.

In the Neochrom-FAT configuration, the analysis of sterols and triglycerides can be performed without changing the chromatographic column, which simplifies the transition between methods and reduces the time of instrument preparation.
