The basic experimental data for the new guideline VDI 3869 Part 4, "Measurement of ammonia in ambient air; Sampling with passive samplers; Photometric or ion chromatographic analysis" were determined by intercomparison experiments with passive samplers and denuders between March 2005 and December 2008 in Braunschweig. Three institutions from Germany and Switzerland were involved. Measurements with passive samplers proved to be suitable to determine mean ammonia concentrations. Their accuracy is sufficient to assess air quality with respect to threshold and limit values. However, passive samplers have to be calibrated against a reference method. This article presents the results of the comparison measurements and performance characteristics derived thereof.

Intercomparison measurements at the FAL experimental site in Braunschweig, Germany, started in March 2005 and ended in December 2008, comprising parallel sampling with cylindrical and annular denuders operated by three institutions from Germany and Switzerland. Denuder measurements proved to be reliable and accurate enough to allow for statements with regard to threshold and limit values. In this work, exemplary performance characteristics are communicated. They served as an experimental basis for the establishment of Guideline VDI 3869, sheet 3 "Measurement of ammonia in ambient air. Sampling with diffusion separators (denuders). Photometric or ion chromatographic analysis".
