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 150oC 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.
