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).
The GC’s can be used to identify and quantify samples taken from the RCMs and counterflow burners.
