GB/T 8038-2009 Toluene of coal carbonization—Determination of hydrocarbon impurities gas chromatographic method
Abstract
This standard specifies the principles, sampling, reagents, instruments and materials, preparation work, test steps, result calculation, and precision for the gas chromatography determination of hydrocarbon impurities in coking toluene. This standard is applicable to the determination of hydrocarbon impurities in coking toluene, including benzene, C8 aromatic hydrocarbons, and non-aromatic hydrocarbons up to n-nonane. The measurement range for each group of impurities is 0.01% to 0.03% (by mass fraction).
