Abstract
A new element selective detector for gas chromatography is presented. The detector, based on wavelength modulation diode laser atomic absorp tion spectrometry in a microwave induced helium plasma, is used for me asurements of chlorinated hydrocarbons by absorption of excited, metas table chlorine atoms. Indications of complete dissociation of the halo carbons in the plasma have been found. Preliminary detection limits of the order of 1 mu g ml(-1) or 80 pg s(-1) have been found for differe nt halocarbons.
