A representative chromatogram of native RSSC (red) superimposed with artificial sebum (black) showing the elution pattern of squalene, wax esters, triglycerides in positive ionisation (a) and free fatty acids in negative ionisation (b). In addition, two diglycerides were identified in the native RSSC (a). The inset figures represent expanded chromatographic regions of interest
