Electrical aerosol spectrometer
Aerosol charging
High charging efficiency allows sufficient charge to be placed on individual particles that the use of electrometer detectors is practicable , while the use of parallel electrometer detectors allows real time measurement of the size/number spectrum with output data as fast as 0.25 Hz.
