Abstract
High-efficiency condenser-type diffusion denuders of cylindrical and planar geometries are described. The film condensation of water vapor onto a cooled denuder surface can be used as a method for collecting water-soluble gases. By using SO2 as the test gas, the planar design offers quantitative collection efficiency at air sampling rates up to 5 L min -1. Coupled to ion chromatography, the limit of detection (LOD) for SO2 is 0.014 ppbv with a 30-min successive analysis sequence. The method has been successfully applied to the analysis of temperature- and humidity-controlled cleanroom air.
