2060 MARGA M – Continuous air monitoring
Metrohm Process Analytics
The Monitor for AeRosols and Gases in Ambient air (MARGA) uses ion chromatography to monitor air quality by measuring the concentration of water-soluble gases and aerosols in air containing different sizes of particulate matter. Air is drawn into the instrument by a vacuum pump at a constant flow rate. Before entering the instrument, the maximum size of particulate matter (PM) can be limited by utilizing a size-selective inlet (e.g. PM 1.0, PM 2.5, or PM 10). The water-soluble gases are absorbed in a Wet Rotating Denuder (WRD) device and then the water-soluble ions in the aerosols are extracted in a Steam-Jet Aerosol Collector (SJAC).
The 2060 MARGA M version is ideal for 24/7 continuous monitoring at a permanent site.
Data collection with a time resolution of 1h to study e.g. diurnal variation or trajectory models for pollution events.
Remote control or touch screen to easily access results, trend graphs, and more.
