Distillation D86 by fast GC whole sample analysis

Oil industry started long before 1900 and is older than gas chromatography, so test distillation was used for sample analysis and not GC. Fast GC analysis of Diesel and Jetfuel already is a standard but Gasoline is not. Detailed hydrocarbon analysis (DHA) with pattern recognition uses GC analysis input to separate and identify gasoline and blendfeed compounds in 6 minutes. The composite report of DHA is input for the fugacity filmmodel of ASTM method D86 distillation. GC post-run software allows the user to obtain physical distillation data in 5.8 minutes. The DHA-Fugacity Filmmodel software has advantages for sample throughput, cost per analysis and safety. Reproducibility from a 9 laboratory cross check and results from our Rotterdam refinery test site will be presented.
