Tampere University Foundation sr (Tampere University, TAU) is asking for tenders for a mass spectrometer based on proton transfer reaction according this call for tenders and its attachments.

The criteria of the acquisition have been described in more detail in the invitation of tenders.

High resolution mass spectrometer based on proton transfer reaction (PTR-MS). The instrument must have a continuously operating atmospheric pressure inlet, mass resolution power of at least 10000, and it must be feasible for mobile use. Furthermore, the instrument weight must be less than 250 kg, and power consumption less than 2 kW. The mass spectra must be obtainable with time intervals of 1 s or less.

The Aerosol Physics Laboratory of Tampere University (https://research.tuni.fi/aerosolphysics) studies air quality as well as the emissions of engines, vehicles and traffic. The studies cover experimental measurements in engine and vehicle laboratories and in aerosol laboratory, on-road exhaust measurements of individual vehicles in real-world driving environment, roadside and on-road measurements in urban environment as well as modeling studies. The PTR-MS is used to expand the measurement capability to real-time chemical characterization of reactive trace gases. It will be used both in laboratory installations as well as with the aerosol mobile laboratory platform ATMo-Lab.
