Comparison of correlation equations for the prediction of gas chromatographic separation of alkylbenzenes

Abstract

A detailed statistical analysis, comparing the validity of the best literature recommended equations for prediction of retention indices of alkylbenzenes on squalane and methylsilicone stationary phases with the unified retention index concept, is presented. A comparison with literature sources shows that the unified retention index provides the smallest residual error. Hence, it can be applied for prediction purposes. © 1995 Friedr.
