Abstract

This commentary highlights the issue of real differences between stationary phases that were studied in an experimental paper entitled "Novel stationary phases based on asphaltenes for gas chromatography" prepared by Grzegorz Boczkaj and co-authors (J. Sep. Sci. 2016, 39, 2527-2536). Particularly, a chemometric study has revealed relatively small differences between stationary phases investigated. Moreover, simple principle component analysis calculations enabled the identification of the outlier points within large raw dataset and to find the parameters (variables) that may carry equal information.
