Linking Vehicle Emissions to Gasoline Composition: A PMI Analysis Solution with Gas Chromatography (GC) and VUV Analytics


Introduced by Honda, particulate matter index (PMI) is used by vehicle manufacturers to correlate gasoline composition to emissions. PMI is based on the cumulative chemical and physical properties of gasoline components derived from a complex and lengthy GC-FID Detailed Hydrocarbon Analysis. A fast, accurate and automated PMI solution using GC-VUV and ASTM D8071 is presented.
