![]() Uptake rates for Palmes and Ogawa samplers were positively and linearly associated with wind-speed (P < 0.01 and P < 0.05 respectively). The Ogawa, Ogawa and Palmes samplers explained 93%, 87% and 58% of temporal variation in analyser concentrations respectively. Duplicate relative standard deviation was <7% for all passive samplers. We deployed these passive samplers close to the inlet of a chemiluminescence NO2 analyser at an urban background site in Glasgow, UK over 32 discrete measurement periods. We assessed the precision and accuracy of nitrogen dioxide (NO2) concentrations over 2-day, 3-day and 7-day exposure periods measured with the following types of passive diffusion samplers: standard (open) Palmes tubes standard Ogawa samplers with commercially-prepared Ogawa absorbent pads ( Ogawa) and modified Ogawa samplers with absorbent-impregnated stainless steel meshes normally used in Palmes tubes ( Ogawa).
