The American company BRECHTEL manufactures the MCPC (Mixing Condensation Particle Counter) ultra-fast time response with sensitivity to particles as small as 5nm. Unlike any other CPC, the MCPC grows particles rapidly through the turbulent mixing of particle and butanol-saturated flows.
Benefits & Features.
Scanning size distribution measurements suffer from the slow response times of available particle counters. The MCPC’s fast response increases the time resolution of size distribution measurements by more than a factor of 4. Detects particles as small as 5nm being a extremely compact & light weight equipment. With a low butanol fluid consumption the MCPC has been proven against numerous particle counting standards. The MCPC has reached great result during those testing.
