Comparison of methods for prediction of the retention data of aromatic hydrocarbons on UCON LB 550X and on polydimethylsiloxane

Abstract

A detailed statistical analysis is presented for comparing the validity of selected literature-recommended equations with the unified retention index concept for calculating the retention indexes of alkylbenzenes on UCON LB 550X and naphthalenes on polydimethylsiloxane. Comparison with literature sources shows that the unified retention index provides the smallest residual error for a set of aromatic hydrocarbons.
