Comparison of aerosol electrometers

Project Description

The comparison will involve charged particles in the approximate size range 20 to 100 nm at charge concentrations of about 0.16 x 10-15 to 1.6 x 10-15 (equivalent to 1000 to 10000 single charged particles cm-3).
The comparison is funded with the EMRP Project "Emerging requirements for measuring pollutants from automotive exhaust emissions".
