Aerosol photoemission spectroscopy – APES (in-house development)

Measured quantity: Surface work function (WF) of aerosols (online)
Range: WF < 6.5 eV
Measurement medium: Aerosol

The APES, a proprietary development from the IMVT, enables the determination of the surface work function of gas-borne nanoparticles. This allows for the qualitative detection of adsorbed species, oxide layers, and much more. A resolution of 0.01 eV can be achieved under optimal conditions.
