Gas Chromatography Detectors

Gas Chromatography Detectors by Raymond P. W. Scott. Detector specifications are described including sensitivity, noise, response, pressure sensitivity, flow sensitivity, temperature sensitivity, dynamic range and linearity.


Methods for the experimental determination of many of the specifications are included. The early gas chromatography detectors are mentioned and their history given. The detectors described in detail include the katharometer, the gas density balance, the flame ionization detector (with a detailed discussion on its design and fabrication), the nitrogen phosphorous detector, ionization detectors (includion different argon and helium ionization detectors) and the radioactivity detector. In addition, a further nine less common detectors are also described.
