Liquid petroleum products — Determination of hydrocarbon types and oxygenates in automotive spark ifnition engine fuels - Gas chromatography with vacuum ultraviolet absorption spectroscopy detection (GC-VUV)

Scope

This test method is a procedure for the determination in percent mass or percent volume of hydrocarbon group types (paraffins, isoparaffins,saturates, olefins, naphthenes, aromatics), methanol, ethanol, benzene, toluene, ethylbenzene, xylenes,methanol, ethanol, MTBE, ETBE, and TAME. naphthalene, and methylnaphthalenes in automotive spark-ignition engine fuels using gas chromatography and vacuum ultraviolet detection (GC-VUV).
The concentration ranges for which precision has been determined are as follows:
Property Units Applicable Range
Saturates % Volume 3.5 to 85
Olefins % Volume 0.011 to 44.002
Aromatics % Volume 14.743 to 58.124
Benzene % Volume 0.09 to 2.5
Toluene % Volume 0.698 to 31.377
Ethylbenzene % Volume 0.5 to 3.2
Xylenes % Volume 3 to 19
Methanol % Volume 0.063 to 3.426
Ethanol %Volume 0.042 to 15.991
MTBE % Volume 0.2 to 22
ETBE % Volume 0.2 to 22
TAME % Volume 0.2 to 22
Oxygen % Mass 0.05 to 3.7

The method may be applicable to other concentration ranges, to other properties or to other hydrocarbon streams, however precision has not been determined. The method may be applicable to other oxygenates including iso-propanol, isobutanol, tert-butanol, n-propanol, acetone, and di-isopropyl ether (DIPE), however precision has not been determined
