Analysts interested in quantifying volatile organic compounds or pesticides in liquid samples should consider using the gas chromatography - mass spectroscopy (GC-MS) system. The gas chromatography system heats and volatilizes liquid samples.The volatilized sample is carried through the system into a stationary phase column with an inert helium gas. The stationary phase separates analytes based on their size and/or polarity. After exiting the stationary phase column the sample enters the mass spectrometer. The mass spectrometer detector identifies analytes based on the mass of the molecule and the software creates peaks based on the concentration of the analyte. Analyte concentrations are determined by comparing sample results to a set of standards analyzed during the analytical run.
