Closed chamber gas flux measurements can be made with Protea FTIR analysers to allow researchers in the field of atmospheric gas analysis from agricultural and livestock to measure evolved gases such as N2O, CO2, CO, NH3, and CH4. Nitrous oxide (N2O) and Methane (CH4) emissions from soil, plant and livestock are especially important gases to measure, given their high potential as greenhouse gases (GHGs). NH3, whilst not a greenhouse gas on the scale of N2O, CH4 and CO2, is a major emission from agricultural, such as after the spreading of liquid manure, and steps are required to measure and reduce the NH3 emissions and the effects they have on the ecosystem.

The Tekran 2537 has been used in numerous published studies to measure the deposition or evasion of mercury from natural or contaminated surfaces (i.e. flux measurements). It is anticipated that many mercury flux measurements will be needed in the future to assess the impact of climate change on mercury cycling in the environment. There are two basic ways to do mercury flux measurements. First, the dynamic flux chamber method utilizes a custom enclosure, with controlled air flow, to measure the inlet and outlet concentration over a selected surface to determine the flux over time. Alternatively, the micrometeorological gradient method uses measured concentrations at two levels above a surface. The perfect tool for both flux measurement methods is the Tekran 1110 Two Port Sampler, so the Tekran 2537 can automatically switch between two distinct sampling points. Ask us how we can help you setup a mercury flux system.
