Portable Gas Analyzers

The subject of the procurement of the lot 1 are portable gas analyzers that can measure methane (CH4), carbon dioxide (CO2), water vapor (H2O) and nitrous oxide (N2O). The measuring capability of CH4, CO2, H2O and N2O gases can be met with one (1) or two (2) separate devices. If two separate devices are offered, they both must be able to measure H2O. Luke is planning to purchase two (2) sets of CH4/CO2/H2O/N2O analyzers (2 devices if all the gases are measured with one device) during the spring of 2024. The procurement also includes an option for Luke to purchase five (5) similar sets of CH4/CO2/H2O/N2O analyzers during the years 2025 - 2027. All the analyzers will be used in field conditions in Finland all year round (the analyzers must operate even in temperatures of -25 degrees of Celsius during the winter) for the purposes of forest and agricultural studies. The analyzers measuring greenhouse gases (GHG) will be mainly used on arable land and peat soils in accordance with the dark chamber method where analyzers are attached to a chamber that is taken to the field and GHG fluxes are measured in situ. Technical requirements for the devices are described in more detail in the procurement object criteria. The contract of the lot 1 will be made with one supplier.

The subject of the procurement of the lot 2 are portable gas analyzers that can measure carbon isotopes d13C (carbon 13/12 ratio) from CO2 flux. The d13C isotope analyzers will be mainly used in remote locations in forest and peatland -ecosystems for quantification of isotopic composition of CO2 flux measurement from soils and from vegetation. Luke is planning to purchase one (1) carbon isotope analyzer during the spring of 2024. The procurement also includes an option for Luke to purchase three (3) carbon isotope analyzers during the years 2025 - 2027. Technical requirements for the devices are described in more detail in the procurement object criteria. The contract of the lot 1 will be made with one supplier.
