Inside the Particulate Monitor – Filter Samplers
Some time ago, OPSIS published descriptions on how some well-established types of gas analysers work, namely those based on spectrometers, interferometers, and tuneable diode lasers. They all utilize absorption of light to determine the concentrations of gaseous pollutants such as nitrogen oxides (NOX), sulfur dioxide (SO2), hydrogen chloride (HCl), ammonia (NH3), and many more. The same ...
