CONDENSED PARTICLE COUNTING APPARATUS

摘要

The present invention provides a condensed particle counting apparatus, comprising: a housing; a distributor having a distributor body arranged on the housing, a distributor inlet portion connected to the distributor body to enable the ingress of an aerosol, and a distributor flow line for discharging the aerosol from the distributor body; a saturator disposed beneath the housing and which is in fluid communication with the distributor flow line to saturate the working fluid with the aerosol; a condenser disposed in the housing and which is in fluid communication with the saturator to condense particles in the aerosol with which the working fluid is saturated; a virtual impactor which is disposed downstream from the condenser, and which classifies the aerosol by a preset ratio to concentrate the condensed particles; and an optical counter which is disposed downstream from the virtual impactor, and which is in fluid communication with the virtual impactor to count the concentrated particles in the condensed aerosol.
