摘要：

Peroxyacetyl nitrate (PAN) at ppb-ppt levels is produced by irradiating a mixture of acetaldehyde and NO2 dynamically generated by permeation tubes. The quantitative and selective removal of NO2 and ozone from the reaction mixture performed by using two annular denuders allows the quantification of PAN as nitrite by ion chromatography carried out on the hydrolysed sample. The method is suitable for the field calibration of GC-based PAN-analysers.
