Alignment for comprehensive two-dimensional gas chromatography with dual secondary columns and detectors.
In each sample run, comprehensive two-dimensional gas chromatography with dual secondary columns and detectors (GC × 2GC) provides complementary information in two chromatograms generated by its two detectors. For example, a flame ionization detector (FID) produces data that is especially effective for quantification and a mass spectrometer (MS) produces data that is especially useful for chemi...
متن کاملGas Chromatography for Combustion Gas Analysis
A basic discussion of the principles of gas chromatography and a description of a combustion gas analyzer using this chemical analysis techniqlJe are presented. During the past several years the combustion gas analyzer has been used extensively in airbreathing propulsion research projects at the APL Propulsion Research Laboratory to analyze samples from supersonic combustion and fuel-air mixing...
