Product description

For quite some time, the formation and the properties of solid-type nanoparticles have been in the focus of research and development. Innovative technologies for analysis of nanoparticles are available for use in e.g. air pollution and emission measurement. Scientists at Institute for Technical Chemistry have developed a particle mass spectrometer (PMS) for simultaneous online measurement of nanoparticle velocities, quantities and masses. The novel system is suited for online measurement of high concentrations of charged nanoparticles in flames, microwave plasmas, and other aerosol systems. Being beyond the present state of the art, it allows measurement of size distributions, mass concentrations, and dust surfaces at high number concentrations and by means of a two-stage molecular beam sampling system transfers particles from the aerosol chamber into the PMS. In an electric field with variable field strength in the measurement chamber, the particles charged during the process are diverted from the trajectory. At the outlet of the measurement chamber, the charged particles are collected in a Faraday cup and the escaping current is detected by a highly sensitive amplifier. The particle velocity is measured in parallel to be able to evaluate the distribution of the particle size. The PMS is a robust and mobile instrument which due to its compact design can be adapted easily to the requirements of various particle sources in research and industry. Its main fields of application are nanotechnology and combustion systems. KIT is looking for industrial partners interested in applying the measurement system.
