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.

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.
