Qualitative Analysis and Change in Detector Sensitivity,Although the function of a gas chromatographic detector is generally the determination of the concentrations of all separated components leaving the chromatographic column, recently selective detectors (for example, electron capture detectors, spectroscopic detectors, etc.), which detect only a given type of compound, have found wide usage.

Selective, Chemically Active Sorbents in Gas Chromatography,The actual separation of the components in gas chromatography is determined by the ratio of two opposed factors: the difference in the rates of movement of the chromatographic zone along the column (selectivity of the stationary phase), and their progressive diffusion (efficiency of the column).

Chromatographic Systems in Analytical Reaction Gas Chromatography,sults in new chromatographic systems which should be studied in greater detail since they represent important parts of gas chromatography. The great variety of important practical analytical problems results in an equal variety of possible reaction chromatographic systems.
