Ambient air quality. Guide for the measurement of elemental carbon (EC) and organic carbon (OC) deposited on filters Ingestion-build-189776 2 Reflecting pattern in horizontal1 Scope This Technical Report gives guidance on the measurement of elemental carbon (EC) and organic carbon (OC) following the requirement for the networks of all EU member countries to measure EC and OC in particulate matter from June 2010 at background sites according to the Council Directive 2008 50 EC on ambient air quality and cleaner air for Europe. The Technical Report describes the analytical procedures for determining EC and OC on quartz
