What is BS EN 16339 – Ambient air about?
BS EN 16339 is the third part of the multi-series standard that specifies a method for the sampling and analysis of NO2 in ambient air using diffusive sampling followed by extraction and analysis by colorimetry or ion chromatography (IC). BS EN 16339 can be used for the NO2 measurement in a concentration range of approximately 3 μg/m³ to 130 μg/m3. BS EN 16339 describes the application of a tube-type sampler with either a cylindrical or a slightly conical tube. Its typical uptake rate is about 1 cm3/min. Only for this sampler type sufficient evidence of validation has been found in a literature survey.
