Abstract:

Hydrocarbon samples require several GC methods to be performed to meet product specifications.  Samples are traditionally injected into multiple GC’s to meet the requirements for D2163 (Hydrocarbons), D7423 (Oxygenates), D5504 (Sulfur Speciation) as well as a non-GC instrument for water analysis (Karl Fischer). An improved workflow is presented where a single injection into a Thermo Fisher Trace 1610 GC installed with a VUV LUMA (a Multi-Wavelength Vacuum Ultraviolet Detector) and utilizes Chromeleon CDS to control both GC and LUMA detector.  The unique characteristics of the LUMA allow the chromatography column utilized to be a readily available, moderate cost, porous polymer PLOT column that eliminates the need for separations on multiple specialty, high cost, columns.
