- Model 2060 MARGA M - A402060110C - Continuous Air Monitoring System



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 in to 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).

A dual-channel ion chromatograph (IC) quantifies anions and cations in aerosols and water-soluble gases simultaneously with high accuracies to reach detection limits as low as 0.001 µg/m3.

The analyzer’s performance can be remotely observed by using a direct internet connection to make adjustments when necessary and to access stored results.

  • The 2060 MARGA M version is ideal for 24/7 continuous monitoring at a permanent site.
