D2.3 Higher sample temperature automotive ICAD for sub-23 nm

This report gives an overview of the development of the heated automotive partector (HAP) . This device is based on an existing commercial device (the automotive partector (AP) by naneos particle solutions IIc. that is already successfully deployed in one of the leading commercial PN-PEMS systems. The standard AP complies with current legislation (23 nm d₅₀ cutoff). In this task, the AP was modified so it could be heated and operated at 150^oC to reduce requirements of dilution of the exhaust, and optimal settings were found so that the d₅₀ cutoff could be shifted to clearly lower diameters (10-15nm) . 3 prototype instrument were built, calibrated and their performance with polydisperse aerosol was verified. These prototypes are now available to be used in further parts of the SUREAL-23 project by other partners.
