Gas Chromatography Manufacturers

Gas Chromatography (GC) is a chemical analysis instrument for separating chemicals in a complex sample. A known volume of gaseous or liquid analyte is injected into a column. Since each type of molecule has a different rate of progression, the various components of the analyte mixture are separated as they progress along the column and reach the end of the column at different times. The time at which each component reaches the outlet and the amount of that component can be determined. GC combined with mass spectrometry ( MS) is even more powerful & a widely used method where MS is an analytical technique used to measure the mass-to-charge ratio of ions. It is most generally used to find the composition of a physical sample by generating a mass spectrum representing the masses of sample components. Due to GC/MS popularity as a chemical analysis tool, various chemometrics algorithms have been utilized to classify chromatograms from the instrument output.
