Abstract Information :

Ultrahigh performance supercritical fluid chromatography (UHPSFC) coupled with mass spectrometry (MS) provides an agile and robust analytical platform to meet the challenge of analysis of complex petrochemical material. The selectivity afforded by the different SFC column technologies, mobiles phase and atmospheric pressure ionisation techniques provides approaches to reveal specific chemistries within the sample, with the added benefit of sample compatibility with the solvents used. The technique is particularly powerful for detection and quantitation of polar and polymer species present in samples, e.g. corrosion inhibitors in crude oil, polymeric additives and carrier oils in fuels. UHPSFC-MS can provide complementary and orthogonal data to gas chromatography (GC-MS) data, and can be coupled to high resolution MS and ion mobility MS, where further analytical information can be extracted.
