Abstract

A method can be provided that can individually detect some PAHs and speed up analysis by a method for detecting the presence or absence of a predetermined PAH (molecular formula: M), the method including: step 1 of chromatographically separating a sample containing the PAH; step 2-1 of generating at least one of [M+CH<3>]<+>, [M+C<2>H<5>]<+>, and [M+C<3>H<5>]<+> as a precursor ion by ionization of the PAH using a chemical ionization method with introduction of methane gas, or step 2-2 of generating at least one of [M+CH]<+>, [M+HNC<2>]<+>, and [M+H<2>NC<2>]<+> as a precursor ion by ionization of the PAH using a solvent mediated chemical ionization method with introduction of acetonitrile; step 3 of generating a fragment ion derived from the precursor ion; and step 4 of detecting the presence or absence of the PAH based on the presence or absence of the fragment ion.
