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. BS EN 16339 specifies the application of triethanolamine as the reagent.
Who is BS EN 16339– Ambient air for?
BS EN 16339 on ambient air is relevant to:
- Manufacturers of air quality controlling devices such as diffusers
- Researchers and scientists
- Environmentalists
Why should you use BS EN 16339– Ambient air?
A diffusive sample relies on unassisted molecular diffusion of gases (analytes) through a diffusive surface onto an adsorbent. BS EN 16339 specifies requirements and test methods for the determination of performance characteristics of diffusive samplers used for the determination of concentrations of nitrogen dioxide in ambient atmospheres. The methodology described in BS EN 16339 can be applied to obtain air quality information with a relatively high spatial density that can be used to complement the appropriate siting of fixed monitoring stations, or in the validation of dispersion models. BS EN 16339 describes the performance characteristics and sets the relevant minimum criteria required for determining the concentration of nitrogen dioxide.
In BS EN 16339, performance criteria and test procedures for measuring air quality are provided to test and manufacture air quality measuring diffusers. This helps create an improved solution to deal with harmful gasses emitted by stationary sources, which are very toxic. As a whole, BS EN 16339 is a best practice guidance standard that provides complete requirements and test procedures for determining the concentration of nitrogen dioxide using a diffuser and controlling their quality, which will reduce pollution, increase efficiency, and ease health concerns.
