Ambient Air-Quality Analyser (with Van)

The Metrohm 2060 MARGA is an online ambient-air analyser. Every hour it measures water-soluble acidic and alkaline gases together with the main inorganic ions in airborne particulate matter. It is used by pollution control boards, environmental monitoring networks and atmospheric research institutes to study secondary aerosol formation and the sources of PM pollution. It combines continuous gas and aerosol sampling with automatic dual-channel ion chromatography in one unattended system.

• Gases: HCl, HNO3, HONO, SO2 and NH3 (HF optional)
• Aerosol ions: Cl⁻, NO3⁻, SO4²⁻, Na⁺, NH4⁺, K⁺, Mg²⁺, Ca²⁺ (F⁻ optional)
• Hourly time resolution; gases collected in a Wet Rotating Denuder and particles in a Steam-Jet Aerosol Collector
• Dual-channel ion chromatograph based on Metrohm 940 Professional IC Vario, with conductivity detection
• Internal standard added to each analysis for self-calibration and column performance checks
• Size-selective inlets such as PM10 or PM2.5; unattended for 1 week at 1.0 m³/h or 2 weeks at 0.5 m³/h (10 L absorbent)
• Performance verified by the U.S. EPA Environmental Technology Verification (ETV) programme; M version for fixed 24/7 stations, R version for research campaigns
