Running ASTM Method D4815 for Determining Oxygenates in Gasoline on the Agilent 6820 GC
Abstract:
The analytical method is designed for the determination of ethers and alcohols in gasolines by using the Agilent 6820 gas chromatography system. This method employs one 10-port switch valve and two columns. Specific compounds determined are: methyl tert-butylether (MTBE), ethyl tert-butylether(ETBE), tert-amylmethylether (TAME), diisopropylether (DIPE), methanol, ethanol, isopropanol, n-propanol, isobutanol, tert-butanol, sec-butanol,
n-butanol and tert-pentanol. For quantitative analysis, 1,2-dimethoxyethane (DME) is used as the internal
standard.
