MIRO Analytical AG

MIRO Analytical AG is a high-tech company from Switzerland. We provide scientists, authorities and companies with powerful tool to monitor and report on air pollution and greenhouse gas levels. This enables them to act against air pollution and climate change. Our analyzers use direct laser absorption spectroscopy with multiple Quantum Cascade Lasers (QCLs). This technology allows for multi-compound gas measurements of up to 10 gases simultaneously in one device with high precision and time resolution.

 

Company

MIRO Analytical AG was founded in 2018 as Spin-off of Empa (Swiss Federal Research Institute). Our team develops and produces the gas analyzers at our headquarters in Wallisellen (Zurich, Switzerland) which also serves as a service point for our European customers.

Our products are used by researchers in different areas of climate and atmospheric sciences and also by authorities tasked with air-quality monitoring. Today, our customers include researchers from several well-known European institutions, universities and government agencies.

 

Products

MIRO Analytical’s MGA-series consists of a number of gas analyzers for various applications ranging from air-quality monitoring to high-precision monitoring of trace gases for climate sciences.

Highlights of the MGA-series:

  • Measures up to 10 Gases simultaneously: CH4, CO, CO2, SO2, NH3, N2O, NO, HONO, NO2, H2O, and O3

  • Direct measurement of all gas compounds (incl. NO2)

  • High precision for ambient air quality and greenhouse gas monitoring at low concentrations

  • Suitable for mobile measurements (aircraft, marine, and ground-based)

MIRO’s Analyzers have revolutionized and simplified the monitoring of greenhouse gases and air pollutants by enabling simultaneous online measurements of up to 10 gases (CH4, CO, CO2, SO2, NH3, N2O, NO, NO2, H2O, and O3) at high measurement rates, while offering high stability and precision.

 

MIRO’s Analyzer directly measures concentrations of all compounds using mid-infrared direct laser absorption spectroscopy with Quantum Cascade lasers as light sources. This allows for highly specific and accurate gas detection along with maximum measurement sensitivity. Our analyzers are typically free of measurement interferences from other gas species. The intuitive touch screen interface enables fast and easy control. Our analyzers are suitable for various applications from air monitoring to greenhouse gas flux measurements.

 

Application examples

To date several of MIRO’s MGAs are being operated successfully in the field in various applications. For example, mobile monitoring on a car where the MGA is measuring 10 gases (CH4, CO, CO2, SO2, NH3, N2O, NO, NO2, H2O, and O3) or trace monitoring of NO2 in the high-altitude research station on Jungfrau-Joch, Switzerland (3571 m.a.s.l.).

 

MIRO MGA10-GP for mobile monitoring

To demonstrate the application of MGA10-GP for mobile real time monitoring of greenhouse gases and pollutants in cities, we performed a measurement campaign in collaboration with the Canton of Zurich (AWEL). During this campaign a MIRO MGA10-GP instrument was installed in an electric mini-van. The analyzer was powered by 3kWh battery sufficient for >10h operation, coupled with a GPS antenna and a particle counter.

The mini-van travelled back and forth through Gubrist tunnel (length 3.2 km) and on the roads around Zurich. The graph below shows the trace gas concentrations of 9 compound during passages of the tunnel. One can see the corresponding fingerprints of various pollutants emitted by the vehicles in the tunnel. Additionally, a difference between the two passage directions can be observed which is due to the height difference of the two tunnel portals. This causes a continuous load on the engines in the uphill direction.

 

MIRO MGA-NO2 on Jungfrau-Joch

An MGA-NO2 was installed at the Jungfrau-Joch monitoring station of NABEL in June 2020 and is reporting live NO2 data since then (link). The figure below presents the results of parallel measurements with MGA-NO2 and CLD analyzer with a photolytic converter as a reference device.

The detailed comparison of the measurement results demonstrates excellent agreement between the reported NO2 concentrations of the two devices. The advantages of the MGA-NO2 over conventional analyzers lie in the fact that it uses a direct measurement without the need of sample pre-treatment. Additionally, the MGA is free of interferences and has a very high time resolution (1Hz).
