AOS: Ultrafine Condensation Particle Counter - aoscpcuf

The condensation particle counter (CPC) measures sub-micron aerosol particle number concentration by condensing fluid onto particles and causing them to grow to sizes that are easily detectable by optical scattering. The condensing liquid is typically an alcohol (e.g., butanol) or water. \n \nDepending on the CPC type, typical CPC instruments can count particles with sizes that range from 3 to 3000 nanometers (ultrafine CPC) or from 10 to 3000 nanometers (fine CPC). The CPC is part of the aerosol observing system (AOS).

凝聚粒子计数器（condensation particle counter, CPC）通过将冷凝液涂布于粒子表面并使其生长至可通过光散射法便捷检测的粒径范围，从而实现亚微米气溶胶粒子数浓度的测量。该仪器所用的冷凝液通常为醇类（如丁醇）或水。
根据CPC的机型差异，典型CPC设备可检测的粒子粒径范围存在两类标准：超细CPC的检测粒径范围为3至3000纳米，细粒子CPC则为10至3000纳米。CPC属于气溶胶观测系统（aerosol observing system, AOS）的组成部分。
