METHOD Sample preparation for gas chromatographic determination of organochlorine pesticides in blood

摘要

A method of sample preparation for gas chromatographic determination of organochlorine pesticides in blood comprising pesticides extracted from blood n-hexane, removing substances soekstrativnyh concentrated sulfuric acid, the concentration of n-hexane extract, characterized in that for the research taking 5-7 cm3 blood and pre-extraction before the sample was treated with 2 cm @ 3 of 60% sulfuric acid, extraction is carried out 30 cm3 of n-hexane and once before the gas chromatographic study of n-hexane extract once treat 10 cm3 of concentrated sulfuric acid.
