Scope
This standard specifies the method for the determination of aniline compounds in gasoline by gas chromatography-mass spectrometry. This standard is applicable to the determination of aniline substances in gasoline. The aniline compounds in this standard include aniline, o-methylaniline, m-methylaniline, p-methylaniline, N-methylaniline, N,N-dimethylaniline . The determination range of each aniline compound is 10 mg/L~1 000 mg/L, and the content exceeding this range can also be determined by this method, but the precision is not investigated. Alcohol compounds, ether compounds, acetone, ethyl acetate, sec-butyl acetate and dimethyl carbonate in gasoline do not interfere with the determination of aniline compounds by this method.
