Gas Analysis

Bruker OMEGA 5 is an all-in-one FT-IR gas analyzer for automated, high-precision, real-time monitoring of gas concentrations. Housed in a 19-inch rackmount enclosure, it uses a 5-metre multi-reflection gas cell that can be heated to 191 degC and a TE-MCT detector, so continuous measurement is possible without liquid nitrogen cooling. A high-resolution option pushes spectral resolution below 1 cm-1 (standard: better than 2 cm-1), which helps separate overlapping infrared signals in complex gas mixtures, and a high-pressure option extends measurements up to 15 bar absolute at temperatures up to 30 degC (standard: up to 2 bar) - useful for detecting extremely low gas concentrations.

Key features:

• 19-inch rackmount housing for automated, continuous operation

• 5-metre multi-reflection gas cell, heatable to 191 degC

• TE-MCT detector - no liquid nitrogen required

• Optional resolution better than 1 cm-1 for complex, overlapping gas mixtures

• Optional high-pressure measurement up to 15 bar absolute

Typical applications:

• Continuous, unattended gas concentration monitoring

• Detection of trace gas concentrations in complex mixtures

• Process environments requiring heated, high-pressure sampling

The Bruker MATRIX II-MG Series comprises four high-performance FT-IR gas analyzers in a compact, rugged housing, built for automated, high-precision, real-time monitoring of gas concentrations. Each system can be configured to the application: detector choice ranges from liquid-nitrogen or Stirling-cooled MCT for exceptional sensitivity, to DLaTGS for extended spectral range, to TE-MCT when liquid nitrogen is unavailable but low detection limits are still required. Spectral resolution better than 1.0 cm-1 (optionally better than 0.5 cm-1) separates overlapping infrared signatures in complex gas mixtures, while a scan rate of up to 5 Hz at 0.5 cm-1 resolution, combined with a fast gas exchange option, makes the series suitable for exploring rapid processes.

Key features:

• Four configurable models in a compact, rugged housing

• Detector choice: liquid-nitrogen/Stirling-cooled MCT, DLaTGS or TE-MCT

• Spectral resolution better than 1.0 cm-1, optionally better than 0.5 cm-1

• Scan rate up to 5 Hz at 0.5 cm-1 resolution

• Fast gas exchange option for rapid process analysis

Typical applications:

• Automated, real-time gas concentration monitoring

• Analysis of complex gas mixtures with overlapping IR signatures

• Fast kinetic and process studies requiring high scan rates

Bruker's MGA Series covers powerful, laser-based gas analyzers with ppb to ppt precision for monitoring greenhouse gases and air pollutants. Three models scale to the task: the MGA 10 is a high-end, all-in-one analyzer that measures up to 10 gases simultaneously; the MGA 5 focuses on specific applications such as greenhouse gas monitoring; and the MGA 3 delivers high-precision monitoring of up to three gases. The MGA 10-GP can be used as a table-top device or installed in a 19-inch rack, with most functions controlled intuitively through a front-panel touch display.

Available models:

• MGA 10 - all-in-one analyzer, up to 10 gases simultaneously

• MGA 5 - focused analyzer for specific applications such as greenhouse gas monitoring

• MGA 3 - high-precision monitoring of up to three gases

• MGA 10-GP - table-top or 19-inch rack installation with touch-panel control

Key features:

• Laser-based detection with ppb to ppt precision

• Simultaneous multi-gas measurement (up to 10 gases on the MGA 10)

• Table-top or rack-mount installation flexibility

• Intuitive touch-panel control of most functions

Typical applications:

• Greenhouse gas monitoring

• Air pollutant measurement

• High-precision trace gas analysis

Bruker Optics offers a broad portfolio of FT-IR-based remote sensing systems that identify and quantify gases from a distance rather than requiring a sample to be brought to the instrument. The range spans open-path monitoring, passive and solar-absorption spectrometers, gas imaging and dedicated chemical-warfare-agent detection, so a system can be matched to the required range, mobility and gas type. The Open Path Spectrometer (OPS) automates real-time quantification of multiple gas compounds up to 500 metres away with extremely low detection limits, while the EM 27 is a mobile passive system with high optical throughput and low spectral noise for fast identification over long distances. The EM 27/SUN tracks the sun to quantify atmospheric gases such as greenhouse gases by solar absorption, SIGIS 2 automatically identifies and visualises dangerous gas compounds from a distance and is used by emergency response forces worldwide, and the HI 90 hyperspectral imager reconstructs 3D gas clouds tomographically for real-time visualisation.

Available systems:

• OPS Open Path Spectrometer - real-time multi-gas quantification up to 500 m

• EM 27 - mobile passive remote sensing, high throughput, low noise

• EM 27/SUN - solar-tracking absorption spectrometer for atmospheric gas quantification

• SIGIS 2 - scanning infrared gas imaging for hazardous gas identification, used by emergency responders

• HI 90 - hyperspectral imager with 3D gas cloud reconstruction

• RAPIDplus - military-proven, real-time chemical warfare agent and toxic industrial chemical detection

Typical applications:

• Long-distance gas leak detection and quantification

• Atmospheric and greenhouse gas monitoring

• Emergency response to hazardous gas releases

• Chemical warfare agent and toxic industrial chemical detection

Bruker OPUS GA is gas analysis software that controls MATRIX-MG and OMEGA 5 gas analyzers through an easy-to-use graphical interface, letting operators run fast, continuous, fully automated identification and quantification of gas compositions without spectroscopy expertise. Quantification relies on a non-linear fitting algorithm that matches a reference spectrum of the target compound to the measured spectrum, allowing accurate detection even when interfering gases are present at high concentration, since those interferences are accounted for in the fitting procedure. The analysis routine also compensates for varying gas temperature and pressure. For integration into a process control system, OPUS GA supports Modbus TCP/RTU, analog output and a web interface for transmitting results and measurement status.

Key features:

• Graphical interface controlling MATRIX-MG and OMEGA 5 analyzers

• Fully automated, continuous gas identification and quantification

• Non-linear fitting algorithm accounts for interfering gases

• Compensation for varying gas temperature and pressure

• Modbus TCP/RTU, analog output and web interface for process integration

Typical applications:

• Automated gas analysis with minimal operator training

• Continuous process monitoring integrated into control systems

• Accurate quantification in gas mixtures with interfering compounds
