Isotope ratio mass spectrometer (CF-IRMS)

Please note that this is a prior information notice and that this notice is not yet a call for tenders. The information provided in this notice is preliminary and may change as the preparation progresses. The aim is to publish the final call for tenders in April 2024. THE SUBJECT-MATTER OF THE PROCUREMENT Target of this procurement is a continuous flow isotope ratio mass spectrometer (CF-IRMS) intended for the use of measuring stable isotope ratios at the Stable Isotope Laboratory of Luke at the Natural Resources Institute Finland. The Stable Isotope Laboratory of Luke performs stable isotope analyses of natural samples with the research focus of forestry, agriculture and related environmental sciences. The laboratory currently hosts a Sercon 20-22 Stable Isotope Ratio Mass Spectrometer with Europa EA-GSL Sample Preparation System (Sercon), HT-EA unit (Sercon) and a Cryoprep-2 unit (Sercon) all operated with Callisto (v3011) program. Also housed in the laboratory is a UV-laser ablation system LSX-213 G+, operating on a Chromium (2.4.) Program, manufactured by Teledyne Photon Machines, which is coupled with the Cryoprep-2 unit and the Sercon 20-22. The target of this procurement is a stable isotope ratio mass spectrometer (IRMS), which will be coupled with the combination of peripherals including the Cryoprep-2 and LSX-213 G+ units housed in the laboratory. The IRMS will be used in continuous flow mode to analyse the stable isotope composition of (at least) carbon and oxygen of small amount of laser ablated material (e.g. approximate amount of carbon per laser ablation analysis is 5-8 µg). This analysis type can be described as laser ablation-combustion-GC-isotope ratio mass spectrometry. The IRMS must be compatible with the following two peripherals, Cryoprep-2 unit, and the 213 nm UV laser model ‘LSX-213 G+’. The instrument must be suited for the precise analysis of δ13C and δ18O values, and should allow the precise analysis of δ2H, δ15N and δ34S values from H2, CO2, CO, N2, N2O, NO, O2, SO, and SO2 gasses (m/z 1-66). Included into the procurement are all the necessary equipment and computer programs that are needed for the instrument to perform in its stated purpose.
