Feature overview

The MARGA system is a semi continuous Monitor for AeRosols and Gases in Ambient air. The analytical system is capable of quantifying anions and cations in aerosols and water soluble gases simultaneously. First the gases are absorbed in a Wet Rotating Denuder device and then separated from aerosols in a Steam-Jet Aerosol Collector.
Two ion chromatographs detect and analyze the collected gas and aerosol samples with high accuracies to reach detection limits as low as 0.01 µg/m³.
The analyzers performance can be remotely measured using a direct internet connection to make adjustments when necessary and to access stored results.

MARGA's performance has been verified by the U.S. EPA Environmental Technology Verification (ETV) program.
