The article shows the importance of the study of feed for broiler chickens on the content of organochlorine pesticides. These substances in significant concentrations can disrupt the development of birds and cause mass poisoning. The study of formula feed for broiler chickens «prestart» and «start» by two methodswas conducted: a certified method for the determination of organochlorine pesticides in feed and formula feed (thin layer chromatography) and a method for detecting pesticides not certified for feed (gas-liquid chromatography with mass spectrometer detector). During the experiment, the presence of organochlorine pesticides in several formulafeed samples was revealed.

Abstract Gas-liquid chromatography (GLC) using a mass spectrometer (MS) as a detector is used for the quantitative determination of cocaine HCl in powders. After the sample is dissolved in methanol containing deuterated cocaine HCl internal standard, an aliquot is injected into the GLC-MS system with the mass spectrometer operating in the scan mode. The cocaine HCl concentration is calculated from the 303/308 m/e ratio. The procedure has a relative deviation of approximately 2.3% and is applicable to samples containing a wide variety of diluents and adulterants.
