Personal thoracicCIP10-T sampler and its static version CATHIA-T

摘要

A specific version of the personal aerosol sampler CIP 10 was designed, named CIP10-T, for sampling the conventional CEN thoracic fraction. A static sampler, named CATHIA, was also designed. It uses the same sampling head, but the size selected particles are collected onto a filter. The combined particle efficiency of the aspiration slot and the selector was measured in a horizontal Wind tunnel at low air velocity, close to 16 cm s~-1. The flow rate of both samplers was fixed at its Nominal value, i.e., 71min~-1. Two different methods weee used: the former was based on the Aerodynamic Particle Sizer(TSI); the latter used the measurement of particle size distribution of the collected samples by the Coulter technique.
