Measuring the particle number concentration of ultrafine particles in ambient air is mainly done using a single particle counting technique, and focuses on particles in the size range of ~1 nm to ~1 μm. This technique utilizes a condensation process to make those tiny, invisible particles visible to an optical counter. These Condensation Particle Counters (CPCs) work over a wide range of concentrations, and can therefore be used both in heavy polluted areas and at background stations. The European standard CEN/TS 16976 describes the use of CPCs to determine atmospheric aerosol number concentrations.
