The use of gas simultaneous detection of benzene substances and ether substances in solvent based coatings chromatography with hydrogen flame ionization detector was established, test method was mainly optimized according to the effect of extraction and separation of toluene, ethyl benzene, and ether compounds. According to GB 18581, using the internal standard, the samples were paint diluted, filtered, and detected. The results showed that benzene substances and ether compounds had good detection limits, the recovery rate of sample was 80% ~105%, the relative standard deviation was 5%, the detection limits were able to fulfill the requirements of the standard.
