Correlating Gas Chromatographic Liquid Phases By Means of a Nearest Neighbor Technique: A Proposed Set of Twelve Preferred Phases

Abstract

A system for reducing the necessary number of GC liquid phases is proposed. A set of twelve preferred liquid phases is given and a nearest neighbor technique is used to show correlations in the comprehensive tabulation of liquid phase data published by McReynolds. The nearest neighbor technique is also used to decide which of the preferred phases can best be substituted for most of the phases currently in use.
