Determination of Chlorinated Pesticides in Poultry Fat Using GPC and Optional Alumina Clean-up with GC-ECD Detection
26 Sept 2017Poultry Fat is routinely monitored for the presence of chlorinated pesticides insuring that consumers are not exposed to unacceptable levels of pesticides and that unauthorized use of these pesticides is detected. Determination of chlorinated pesticides in poultry fat requires post-extraction clean-up steps to effectively remove lipids and other co-extractives prior to analysis by GC or GC/MS. Failure to remove these compounds results in decreased column life, contamination of the ion source and decreased analytical performance. This application note describes the post-extraction clean-up of poultry fat followed by an optional alumina clean-up step performed in a special filter rack placed on-line to the GPC eluent.

Food and Beverage AnalyzersFood and Beverage Analyzers are commonly used to provide information about the chemical composition, structure and physical properties of food materials.GC-MS GC-MS (gas chromatography-mass spectrometry) instruments and equipment are used to separate, quantify and identify mixtures of small and volatile compounds, such as polycyclic aromatics, fatty acids and alcohols. Often used in drug detection, forensic investigation and environmental analysis for pesticides and contaminants, GC-MS is a powerful addition to your lab’s analytical capabilities. GC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzers can give greater sensitivity and resolution to your analysis. Find the best GC-MS instruments and equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.PesticidesPesticides are used to protect crops from diseases, pests and unwanted plants. They are classed as persistent organic pollutants (POPs) and can be harmful to humans. The Environmental Protection Agency (EPA) currently regulates the use of pesticides in the USA. Food SafetyFood safety describes the prevention of food-borne illnesses. Contamination with a variety of pathogens can be prevented with adequate temperature control, hygiene and labeling. Food samples can be tested using GC/MS, HPLC, SPE, and qPCR to ensure their adherence to regulations.ChromatographyChromatography is a powerful technique used to separate and analyze components of mixtures based on their chemical properties. It is widely used in fields like biochemistry, pharmaceuticals, and environmental analysis. By exploiting differences in the interaction of substances with a stationary phase and a mobile phase, chromatography enables precise purification and quantification of compounds. Whether you're working with complex biological samples or industrial chemicals, chromatography is essential for obtaining high-quality results.
