Intercomparison and Evaluation of the TSI NanoScan SMPS and the GRIMM Mini WRAS Ultrafine Particle Size Spectrometers

An inter-comparison workshop was held at the World Calibration Center for Aerosol Physics (WCCAP) in Leipzig, Germany, from January 27-31, 2020. Manufacturers and users were invited to have their portable instruments tested and compared against reference instrumentation for particle number size distribution (PNSD) and total particle number concentration (PNC). In particular, the performance and uncertainties of the NanoScan SMPS (Scanning Mobility Particle Sizer) Model 3910 (TSI Inc.) and the Mini Wide Range Aerosol Spectrometer (WRAS) Model 1371 (Grimm Aerosol Technik) were investigated against the WCCAP Mobility Particle Size Spectrometers (MPSS) and Condensation Particle Counters (CPC). A total of 11 TSI NanoScan SMPS and 4 GRIMM Mini WRAS instruments were characterized for ambient aerosols as well as lab-generated aerosols. 

The data set represents the respective data for each ambient inter-comparison measurement and performance evaluation using lab generated aerosols such as PSL, NaCl etc.
