Multicapillary column gas chromatography with element-selective detection
Résumé
Multicapillary column gas chromatography (MC GC) is presented as a novel technique for the time-resolved sample introduction of gaseous analytes in atomic spectrometry. The principles and the theory of MC GC, the coupling of MC GC with microwave-induced plasma atomic emission spectrometry and with inductively coupled plasma mass spectrometry, and features of the coupled techniques developed are discussed. Applications of MC GC with element-selective detection to species-selective analysis are reviewed. The possibility of incorporating MC columns into dedicated sample preparation accessories for elemental speciation by atomic spectrometry is evaluated. Copyright (C) 1999 Elsevier Science B.V.
