Dual Channel Gas Chromatography,tances obtained with an electron capture detector and an argon detector I.]. In addition to showing two chromatograms, dual channel gas chromatography offers more than twice the qualitative and quantitative information than is available in a single channel system.

Galvanic-Coulometric Detectors in Gas Chromatography,dation of one molecule means stripping it of 14 × 4 + 10 × 1 = 66 electrons. Thus, a stream of fewer than 100 molecules per sec of this compound is detectable in principle. In the case of compounds with more carbon and hydrogen atoms in the molecule, the sensitivity in these terms is higher still, compensating for their lesser volatility.

Analysis of Some Nonprotein Amino Acids by Gas Chromatography,imited, and maintaining the apparatus takes up scarce technical manpower. Gas chromatography holds out great promise in overcoming these drawbacks, but the accuracy. of the quantitation achieved by ion-exchange chromatography sets a high standard against which to measure gas chromatographic methods, and this has been approached only recently [.].
