Abstract
An oscillating plasma glow discharge detector for gas chromatography can be used to help identity an analyte by combining the current and oscillation frequency signals. Five homologs each of the n-alkanes, 1-alkenes, 1-alkynes, 2-ketones, and aldehydes were studied. Although triplicate determinations had some scatter due to noise, they showed clustering that allows several of these compounds to be distinguished from the others by using a two-dimmensional plot of the ratios of frequency peak area to current peak area and frequency peak height to current peak height
