What is GC?
Gas chromatography (GC) is a technique used to physically separate, identify, and quantify volatile and semi-volatile compounds in a complex mixture. A sample is converted into a vapor and carried through a column of gas, which separates the sample into components that are then analyzed by a detector – either a mass spectrometer (MS) or flame ionization detector (FID).
Applications of GC
Our GC-MS and GC-FID capabilities will help you identify and measure mystery volatile compounds to organic impurities and more at trace levels – ppm (parts per million) and ppb (parts per billion). Depending on your testing and product development needs, our specialists will help you decide which technique is right for you.
