“…As a perspective, new intercomparison studies will be organized on the measurement of the aerosol size distribution by involving optical (WRAS, WELAS, Dusttrack), aerodynamic (APS, ELPI, cascade impactors) and electrical mobility sizers (SMPS, FMPS, DMS, nanoscan ...) by sending a same transportable reference aerosol generator to each participant in the same way of the work performed by Gaie-Levrel et al (2017) about particle mass concentration. Fig8: Average PNSD for aerosols generated from the water nebulization only, by each participant and measured by each involved SMPS.…”

An intercomparison exercise of good laboratory practices for nanoaerosols size measurements by mobility spectrometersAn intercomparison campaign on nanoparticle size measurement was organized in the frame of the French nanoMetrology club. The aim of this study is to make an inventory of the metrological capabilities of all measurement techniques in France involved in the "nano" size range, including the SMPS (Scanning Mobility Particle Sizer) concerning aerosol metrology. For this study, four samples have been proposed, namely (1) -a SiO 2 colloidal suspension (FD304) consisting of a monomodal population, (2)two samples consisting of two nanoparticle populations of SiO 2 having proportions to be determined and(3) -a TiO 2 colloidal suspension. Ten SMPS associated to five participants around a common experimental setup were performed in link with a control SMPS to have simultaneous measurement s with a same instrument in each laboratory in parallel with the SMPS used by each partner. This article presents SMPS results of this study associated with the description of the experimental set -up and the sample preparation protocol with an identified schedule and comparison with SEM measurements. The present paper does not focus on the actual capability of the tested mobility spectrometers, but aims to highlight s the good laboratory practices using their own but common resources in terms of aerosol generation and measurement set-ups.

The serious pollution of particulate matter causes many adverse effects on human health and industrial production. High-precision, real-time monitor of atmospheric particulate concentration is becoming increasingly important. In this study, a method to find the optimal detection angle to measure the mass concentration of particulate matter is proposed. To find an optimal angle, a motorized rotary system is used to measure the light scattering signal of particles from 0° to 180°. The new method obtains parameters such as mass concentration factor, deviation, mass concentration coefficient and deviation coefficient, which can be measured more accurately. Through theoretical calculation and experimental analysis, the optimal detection angle is 45°. At the optimal angle, the correlation between the scattered light intensity and the mass concentration of spherical SiO2 particles reaches 0.9836. Then, the mass concentration of particulate matter is inverted and calculated at the optimal angle. The results showed that the correlation coefficient R2 of different particle sizes is larger than 0.952, and the measurement results were highly correlated.
