Chromatographic Manipulation Employing VALCO HayeSep(r) PLOT Columns and Pulse Discharge Detector
Martin Okiro, Robert Wohleb, and Joanne Wolcott
A classical problem in analytical chemistry is the quantification of minor components in a predominantly one-component system. Examples include the quantification by gas chromatography of contaminants in standard gases and certification of analytical carrier gas. Contaminants often elute immediately following the primary component resulting in peak swamping, overlap, and distortion, thus causing quantification difficulties. A solution to this problem is to reverse the component elution order by modification of the stationary phase. If minor components elute before the principle component, identification and quantification are significantly simplified. When reversal is not possible, increased retention time separation may suffice. In this article we explore the gas chromatographic analysis of C1-C5 hydrocarbon mixtures using a variety of ValcoPLOT HayeSep® porous polymer columns.
