DIN EN 16339:2013-11

This European Standard provides details for the sampling and analysis of NO2 in ambient air using diffusive sampling followed by extraction and analysis by colorimetry or ion chromatography. It can be used in a concentration range of approximately 3 µg/m3 to 130 µg/m3. A sample is typically collected for a period of 1 to 4 weeks, with exposure periods depending on the design of the samplers and the concentration levels of NO2.
