MODEL 5522-A
AMERICIUM-241 NEUTRALIZER
Bipolar neutralizer for α radiation - 3.7 MBq
The GRIMM 5522-A aerosol neutralizer is based on the radioactive decay of Am-241 (nominal activity 3.7 MBq), that produces a bipolar ionic atmosphere by α radiation. Irregularly charged particles (from ambient or lab generated) are brought into a defined stationary-state charge distribution, regardless of their initial charging state. Aerosol neutralizers based on radioactive sources are nearly maintenance free and well proven.
Overview
- Am-241 α radioactive source
- nominal activity 3.7 MBq
- aerosol flow rate up to 5 L/min
- low maintenance
- easy to operate and safe
- compatible with GRIMM SMPS+C and SMPS+E systems
Applications
- neutralizer for aerosol sizing with SMPS systems
- neutralizer for particle generators
- fundamental aerosol research
- investigation of particle charging
