摘要：

Time-integrated measurements of PAN have been carried out by sampling ambient air on alkaline alumina cartridges followed by liquid chromatography analysis of acetate with "negative" UV detection (LC-UV). Two cartridges are operated side by side, one at ambient temperature and the other downstream of a thermal converter that decomposes PAN to products other than acetic acid. The first cartridge measures total acetate (PAN + acetic acid), the second measures acetic acid, and PAN is obtained by difference. Good agreement has been obtained between the dual alumina cartridge-LC-UV method and electron capture gas chromatography. Field results are presented and applications of the method are briefly discussed.
