Abstract

The invention provides a particle measurement device and a particle measurement method, and belongs to the technical field of particle measurement. The device comprises a body for supporting, a charge adapter for performing charge adapting operation on particles to be measured, a charge collector for supplying charges to the charge adapter, a charged particle receiver for collecting charge quantity carried by the charged particles, a charge leading-out assembly for leading out the received charges, a charge measurement assembly for measuring the charge quantity, and a particle analysis assembly for making the measured charges correspond to the particle condition. The particle measurement method comprises the following steps of: charging the particles, collecting the charged particles carrying charges, leading out the charges carried by the charged particles, measuring the led-out charge quantity carried by the charged particles, and analyzing the condition of the particles according to the measured charge quantity. Compared with the prior art, the device and the method can identify the number and granularity of the particles more effectively.
