3 Principle
Extract benzene, toluene, ethylbenzene and xylene in the specimen with n-pentane solution which contains the internal standard, and then determine the contents of benzene, toluene, ethylbenzene and xylene in the extract by the gas chromatography-mass spectrometry method to obtain the residual amount of benzene, toluene, ethylbenzene and xylene in the specimen through calculation.
