A Nearest-Neighbor Technique Applied to the Reduction of the Number of Standard Solutes Needed to Characterize Gas Chromatographic Liquid Phases

Abstract

A nearest-neighbor approach has been devised to study the ability of reduced sets of standard solutes (test probes) to characterize liquid phases. Two sets of three test probes and several sets of four probes gave results similar to those obtained using all five of the test probes evaluated by McReynolds. The interactive forces important in gas chromatography are related to those solutes present in the best sets of test probes.
