By using an atmospheric pressure chemical ionization(APCI) source, negative ion mess spectra of eight perchlorinated polycyclic aromatic hydrocarbons(PAH), hexachlorobenzene, perchloronaphthalene, perchloroacenaphthylene, perchloroanthracene, perchlorophenanthrene, perchlorofluoranthene, perchloropyrene and perchlorocorannulene, have been recorded for the first time. In the ion source, the negative ions, whose masses are 19 less than the molecular weights of their pristine compounds, can be produced by losing a chloride atom and capturing an oxygen anion, Molecular ions of the samples can be produced from the perchlorinated PAHs containing a five-membered ring. The results show that APCI is the Fight ion source for mass analysis of the organic compounds with low-polarity such as the perchlorinated PAHs.
