METHOD TO DETERMINE GAMMA-CYHALOTHRIN IN BIOLOGICAL OBJECTS USING THIN-LAYER CHROMATOGRAPHY Russian patent published in 2012 - IPC G01N33/48 G01N30/02 

FIELD: measurement equipment.

SUBSTANCE: invention is related to veterinary toxicology and sanitation. The method includes sampling, extraction, filtration, sodium dehydration by anhydrous sulfate, evaporation, application of the dissolved dry residue onto a chromatographic plate, distillation of movable dissolvents hexane: acetone in the system, treatment with a solution of bromphenol blue with subsequent radiation with ultraviolet beams for 10-15 minutes and treatment of analysis results, the sample is a batch of organs or tissues of animals with weight from 50 to 200 mg, extraction is carried out with ethyl acetate, the dissolved dry residue is applied onto plates for thin-layer chromatography "Sorbphil", the system of movable dissolvents is represented by hexane: acetone (10:1).

EFFECT: invention provides for higher sensitivity and selectivity, as well as acceleration and simplification of analysis.
