Gc fid injector
WebThe flame ionization detector (FID) is the most widely used detector for gas chromatography because of its reliability, versatility, and ease of use. It responds to virtually any organic compound while generating little or no signal for common carrier gases. The auto-ranging FID used on Agilent Intuvo 9000, 8890, 8860, and 7890 GC systems ... WebHeadspace Gas Chromatography. Headspace GC [104] is a sampling and/or injection technique involving the indirect determination of volatile constituents in liquid or solid samples by analysing the associated vapour phase.
