GAS CHROMATOGRAPHY (GC-FID, GC-MS)
GC uses a gaseous mobile phase, usually helium or hydrogen. The stationary phase of gas chromatography is a microscopic layer of liquid or polymer coated on an inert solid support, with capillary glass being the most common. Separation is achieved during gas chromatography when the vaporized compounds interact with stationary phase and elute at different times, known as the retention time of the compound. Detection if done using a flame ionization detector (FID) or a mass spectrometer (MS). We conduct both GC MS and GC FID. Column chemistry and temperature are the parameters used to optimize the separation. Detection limits for FID detection are in the low ppm range, while MS detection can achieve ppt levels. Our team will also provide a detailed GC MS analysis.
We do more than gas chromatography. The list provided is a general list of methods, but we are not limited to the methods. If interested in a method that is not listed, please contact us for further information.
