Abstract

See full text

A measuring apparatus includes

    an input to receive an aerosol sample,a modifier unit to provide a modified sample by removing particles of the aerosol sample, anda sensor unit to measure a spectral profile by detecting molecules of the gas phase of the modified sample,wherein the spectral profile is a mobility spectrum or a mass spectrometer spectrum, the modifier unit is arranged to generate a corona discharge, to form charged particles by charging particles of the aerosol sample with the corona discharge, and to provide the modified sample by removing the charged particles with an electric field, the particle removal efficiency of the modifier unit has a cutoff size to prevent propagation of particles larger than the cutoff size to the sensor unit, and the cutoff size is in the range of 1 nm to 20 nm.
