Gas Chromatograph (Pre-Owned)

Gas chromatography (GC) is a chromatography technique that separates and detects the chemical components of a sample mixture to determine their presence or absence and/or quantities. These chemical components are usually organic molecules or gases. Gas chromatography–mass spectrometry (GC–MS) is an analytical method that combines the features of gas-chromatography and mass spectrometry to identify different substances within a test sample. GC-MS can be used to separate complex mixtures, quantify analytes, identify unknown peaks and determine trace levels of contamination. GC-MS provides enhanced sample identification, higher sensitivity, an increased range of analyzable samples, and faster results, which enable a whole new range of applications for GC-MS in several areas.
