Direct Air Capture (DAC) Testing With FTIR

Using Protea’s FTIR gas analyser, developers of Direct Air Capture (DAC) technology have been able to show the efficiency of removal of CO₂ from the atmosphere. By using a hybrid FTIR that can be used in a fixed cabinet but also removed for portable use, technologists have carried out testing across multiple sample locations within pilot plants.

The FTIR analyser is optimised to measure low range, 0-500ppm CO₂, so that ambient air and then CO₂-free air can be tested. Not only CO₂, but the benefit of FTIR is that other gases in ambient air such as CH₄ and N₂O can also be monitored. Installing the plants near to more highly polluting processes, even ambient NO_x can be measured through the process.
