Ambient air. Measurement of elemental carbon (EC) and organic carbon (OC) collected on filtersWhat is BS EN 16909 Measuring the EC and OC about? BS EN 16909 describes the analytical procedures for determining EC and OC on quartz fibre filters as g cm2 and the subsequent calculation of concentrations. The sampling process determines the size fraction of the particulate matter, the retention of semi volatile material, and the uptake loss of volatile organic compounds on the filter at the time of sampling. BS EN 16909 is applicable for the
