Hypernated supercritical fluid chromatography: Potential application for car lubricant analysis

► This study is a unique example of on-line multi hyphenation of informative detectors in SFC using neat carbon dioxide as the mobile phase. ► It is the demonstration of the best detection features of SFC to advantage for structure elucidation of compounds in very complex mixtures. ► The potential of the technique is demonstrated on real lubricants and packages of additives.
