Thermo Scientific TraceGOLD TG-OCP columns offer a fully separation of organochlorine pesticides in less than 7 min. The TG-OCP I and TG-OCP II column pair is designed with different selectivity, which changes several elution order to fill the conformational requirement of EPA methods.
Accelerated Solvent Extraction (ASE®) is an extraction method that significantly streamlines sample preparation. The procedures described in this application note meet the requirements for sample extraction as prescribed by EPA Method 3545. This method is applicable to the extraction of water-insoluble or slightly water-soluble volatiles and semivolatiles in preparation for gas chromatographic or GC/MS measurement. The method is applicable to the extraction of chlorinated pesticides from soils, clays, wastes, and sediments containing from 5 to 250 μg/kg of the target compounds.
Polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs) and polybrominated diphenyl ethers (PBDEs) belong to a broad family of synthetic organic compounds known as halogenated hydrocarbons. Polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs) and polybrominated diphenyl ethers (PBDEs) belong to a broad family of synthetic organic compounds known as halogenated hydrocarbons. The method reported here is applicable for the determination of 29 halogenated hydrocarbons (6 PCBs, 16 OCPs, and 7 PBDEs) in fish tissues.
The Thermo Scientific Trace 1310 ISQ system is applied for the direct injection of extracted organochlorine pesticide and pyrethroid samples. Separation is performed on a Thermo Scientific TraceGOLD TG-5SilMS column with MS SIM detection.
In this study, a fast, easy, and robust workflow was used to analyze pesticide residues in baby food. Accurate and sensitive detection, quantification, and identification of pesticides in baby foods is of particular importance because babies are more vulnerable to adverse health effects from these chemicals.
