Atmospheric pollutants put a strain on the environment and harbor health hazards for humans. The Empa spin-off MIRO Analytical Technologies developed a technology to simultaneously analyze nine greenhouse gases and pollutants with only one device and at an unprecedented speed and precision. Air pollution is a problem that affects us all. However, instruments to measure greenhouse gases and pollutants in the atmosphere are complex, expensive and usually consume a lot of energy as every gas is measured using a different method. Two researchers from Empa's Laboratory for Air Pollution/Environmental Technology, Morten Hundt and Oleg Aseev, have developed a method that simplifies this process: Using only one device, they are able to detect nine greenhouse gases and air pollutants simultaneously. These also include nitrogen dioxide (NO2), which until now usually could only be measured indirectly, potentially distorting the results. "Our goal is to make air quality and greenhouse gas measurements easier, more accurate and cheaper," says Hundt.
