Particle number concentration measuring instrument

Contracting authority is publishing direct award notice for 'Particle number concentration measuring instrument'.

BACKGROUND INFO One of the research areas of Tampere University Aerosol Physics Laboratory (APL) focuses on the research of emission related aerosols. The existing research infrastructure includes extensive instrumentation for particulate matter characterization in the particle size range starting from approximately 1 nm. In addition to the more traditional aerosol instrumentation, the infrastructure is also equipped with state-of-the art aerosol and chemical ionization mass spectrometers capable of atmospheric pressure sampling. NEED APL is seeking for an instrument to study the particle emission of vehicles. In addition to the direct particle emission of the internal combustion engines the research focuses also on the secondary particle formation potential and the non-exhaust emissions of the vehicles. For this research the APL is seeking a new real-time instrument to measure particle number concentration distribution over a wide particle size range. The instrument must cover a particle size range from 0.01 – 10 µm with single measurement method and with a temporal resolution of 1 second or better. The instrument must also be field-deployable and suitable for mobile installations. MARKET ANALYSIS AND CONCLUSION FOR DIRECT AWARD According to contracting authority’s knowledge, the HRELPI+ offered by Dekati Oy is the only instrument on the market fulfilling the requirements specified above. This instrument is specifically intended for the purpose. For the proper market survey purposes contracting authority has studied instrument offerings of several manufacturers but has not found another instrument fulfilling all requirements.
