Differentiating Polychlorinated Biphenyls (PCB’s) by GC/FID/ECD
6 Jun 2013The analytical chemistry of PCB’s is rigorous, demanding the highest quality in sample preparation and analytical technique. Furthermore, insufficient sample extraction and inappropriate methods of sample clean-up are the most common sources of error in PCB analysis and causes significant interference in the chromatography. This application note demonstrates that the Buck System P gas chromatograph, equipped with EPC split/splitless injector and dual EC detectors can be used for quick field screening where the sources of contamination are known.

Gas ChromatographyGas chromatography (GC) is an analytical technique used to separate and quantitate mixtures of small and volatile compounds. Gas chromatographs or GC systems include components such as GC columns, detectors, pumps and autosamplers. Choose from packed or capillary GC columns, flame ionization (FID), photoionization (PID) electron capture detectors and selective or non-selective detectors. Find the best gas chromatographs in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.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. Browse our peer-reviewed product directory to find the best chromatography systems, compare products, read customer reviews, and get pricing directly from manufacturers.Contamination PreventionContamination prevention aims to control and minimize the risk of contamination during experiments. Biological safety cabinets and sterilization equipment are examples of technologies used to prevent contamination.Environmental ContaminationContaminants in the environment are harmful chemicals that are present in the air, land and water. These include pesticides, pharmaceuticals, persistent organic pollutants (POPs) and many more.Polychlorinated Biphenyls
