Nano mobility particle size spectrometer PSMPS

Nano mobility particle size spectrometer

The PSMPS is a mobility particle size spectrometer with a 2-stage condensation particle counter detection system for delving into the sub-2-nm size range. It combines a Grimm SMPS+C system with the Airmodus Particle Size Magnifier (PSM). 

Functionality: Nano mobility particle size spectrometer with 2-stage condensation particle counter detection system
