Zusammenfassung:THE development of high-sensitivity detectors for the chromatographic analysis of gaseous mixtures is of importance in the determination of substances present in very small amounts. A sensitive ionization gauge detector has been developed in this laboratory which makes use of the fact that the ionization potential of the helium carrier gas (24.5 volts) is very much greater than that of most other volatile substances. The ionization potentials for hydrocarbons, for example, range from 8 to 14 volts.
