2060 MARGA M – Continuous air monitoring


Metrohm Process Analytics

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.

  • Gases measured: Hydrochloric Acid (HCl), Nitric acid (HNO3), Nitrous acid (HONO), Sulfur dioxide (SO2), Ammonia (NH3)

  • Aerosol ions measured: Chloride (Cl-), Nitrate (NO3-), Sulfate (SO42-), Ammonium (NH4+), Potassium (K+), Calcium (Ca2+), Magnesium (Mg2+)
