The Gas Chromatograph (GC) is a standard piece of chemical instrumentation, designed to separate the components of a mixture from one another. In the lab, we have two such devices, each connected to different detectors. The GC-2014 has three detectors: dual Flame Ionization Detectors (FID), and a single Thermal Conductivity Detector (TCD). The GC-2010 is equipped with a Mass Spectrometer (MS). The combination of the GC with each of these detectors provides a unique capability, from identifying trace compounds (MS) to accurately quantifying hydrocarbon species (FID) and permanent gases (TCD).
