Using a Novel Atmospheric Pressure GC Source Coupled to High-Resolution TOF-MS to Analyze Environmental Samples

6 Mar 2015

A new gas chromatography atmospheric pressure chemical ionization (GC-APCI) source coupled to a high-resolution QTOF-MS was used for the GC/MS analysis of polycyclic aromatic hydrocarbons (PAH), pesticide and explosive standards as well as soil, sediment and sludge samples of environmental origin. Compared to an earlier GC-APCI design, the source demonstrated improved GC/MS performance in terms of reproducibility and analytical working range.

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.

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.

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.
