Alphasense now provides a solution to some old problems: * Palmes-type diffusion tubes are commonly used for indicative measurement of nitrogen dioxide (NO2) in cities for Local Air Quality Management. But sampling over several weeks gives only one average concentration for the entire sampling period and the result is reported weeks after the measurement. * Odours which were previously ignored by local industry and city councils are now headline problems. There is a growing requirement to monitor odour plumes around landfills, waste water treatment plants, agricultural/ poultry farms and industrial sites- but the cost of the necessary network of monitoring nodes is prohibitive. Hydrogen sulfide (H2S) or ammonia (NH3) are the two mot commonly measured gases for odour detection.
