摘要：
We have combined a diffusive sampler and ion chromatograph to determine SO2 in ambient air. The sampler is made of a three-piece cassette holder containing a triethanolamine-impregnated glass-fiber filter. We here describe the absorbent used, sample treatment, method of analysis and the assessment of the sampler in the laboratory and on site. We conclude that the samplers are satisfactory for ion-chromatographic measurement of SO2, but problems due to loss of SO2 must be considered during long-term sampling and storage.
