Air quality - Determination of the particle size distribution of atmospheric aerosol

Scope

This Technical Specification specifies measurement methods for the determination of the particle number concentration of atmospheric aerosol within a limited number of size ranges, providing a size distribution in ambient air. The lower and upper sizes to be considered are approx. 10 nm and 10 µm, respectively. This Technical Specifications describes calibration, sampling, operating and QA/QC procedures and data processing.
