摘要：
An oscillating plasma glow discharge detector for gas chromatography can be used to help identify 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-dimensional plot of the ratios of frequency peak area to current peak area and frequency peak height to current peak height.
