Method for testing harmful volatile matters of passenger vehicle interior assembly

The invention discloses a method for testing harmful volatile matters of a passenger vehicle interior assembly. The method comprises the following steps of: filling a certain specific type of automotive trim assembly into a sampling bag; arranging a blank sampling bag with the same specification; separating harmful volatile substances from an adsorption object to be detected through heating; collecting benzene substances through a TENAX sampling tube; extracting benzene substances in the TENAX sampling tube through a thermal desorption system; introducing the benzene substances into a gas chromatography-mass spectrometer; obtaining a quantitative value of each benzene substance through a benzene substance analysis curve; collecting aldehyde ketone substances through a DNPH sampling tube, eluting the DNPH sampling tube through acetonitrile to prepare an aldehyde ketone substance reagent, guiding the aldehyde ketone substance reagent into a high performance liquid chromatograph-diode array detector, obtaining q
