A greenhouse gas (GHG) analyzer and multiplexing system

School of Forest Sciences (University of Eastern Finland) is purchasing a greenhouse gas (GHG) analyzer and multiplexing system (optional) to be used in controlled growth chambers systems of Biosphere Laboratory of Eastern Finland (UEF). School of Forest Sciences (University of Eastern Finland) is purchasing a greenhouse gas (GHG) analyzer and multiplexing system to be used in controlled growth chambers systems of Biosphere Laboratory of Eastern Finland (UEF). The gas concentration analyzer should be capable of precise, simultaneous and continuous measurements of H2O, N2O, NH3, CO2 and CH4. The analyzer should be able to run continuously and reliably from several weeks to months long experiments without substantial maintenance breaks. To assure simultaneous multi-port data collection, an optional multiplexing system is tendered. The multiplexing system should have minimally 8 channels. Multiplexer control should be integrated with an analyzer without significant need for additional programming for an operational setup. Programming of the sequence and duration of sample intake should be easy.
