Section II: Object
Acquisition of a PTR-TOF-MS to Department of Biology
PTR-TOF-MS (Proton Transfer Reaction – Time of Flight — Mass Spectrometre) is a state-of-the-art instrument for simultaneous online monitoring of a large range of volatile organic compounds (VOCs). The analysis is done without sample preparation and very low (ppt-level) concentrations can be measured.
The PTR-TOF-MS will be purchased as part of the research grant for an ERC consolidator project to Riikka Rinnan. The project is entitled “Tundra biogenic volatile emissions in the 21st century”, in which the instrument will be use for Eddy covariance measurements in the Arctic. For this use, a small-size, robust and stable instrument producing reproducible results is needed.

Section IV: Procedure
- The procurement falls outside the scope of application of the directive
Ionicon is the only supplier to provide the required performance (mass resolution, sensitivity) in combination with size and weight of the instrument. The space in the field tent/hut is limited and it can only house a small instrument along the other instrumentation.
While being small, the instrument must provide excellent performance. The PTR-TOF instrument must be able to reach mass resolution > 1500 m/Δm (for m/z >60) and reaching sensitivities of more than 100 cps/ppbv (for m/z 181). It must provide homogeneous reaction conditions (constant electric field, pressure, temperature) in the reaction chamber for predictable reaction conditions of different compounds.
The instrument must be compatible with the PTR TOF 1000 instrument already in the use in the laboratory.
The instrument to be purchased must be documented to function reliably under extreme and variable conditions in the field, including the Arctic. The PTR-MS instruments of Ionicon have been operated successfully in the Arctic e.g. by
— Lunden et al. 2010. The vertical distribution of atmospheric DMS in the high Arctic summer. Tellus B 62:160-171,
— Sjostedt et al. 2012. Evidence for the uptake of acetone and methanol byb the Arctic Ocean during late summer DMS events, JGR 117, D12303,
— Gao et al. 2012. PTR-MS observations of photo-enhanced VOC release from Arctic and midlatitude snow. JGR 117, D00R17.
