Hiden Analytical has announced the availability of its Carbon Monoxide Analyzer, developed to provide continuous, quantitative carbon monoxide (CO) measurement in complex gas mixtures. Designed for integration with Hiden mass spectrometry systems, the analyzer supports researchers worldwide studying syngas, biogas, catalysis and related gas-conversion processes by measuring CO while other gaseous components are monitored simultaneously.

Dedicated CO measurement alongside mass spectrometry

The CO Analyzer integrates with Hiden HPR-20 and QGA 2.0 Gas Analysis systems. It provides dedicated CO measurement while the mass spectrometer monitors other components in the gas mixture.

This combined approach is particularly relevant when nitrogen, carbon dioxide, methane and other species are present and may complicate carbon monoxide analysis.

Demonstrated CO measurement in complex gas mixtures

Testing demonstrated the combined analytical approach using complex gas mixtures containing carbon dioxide (CO₂), argon (Ar), methane (CH₄) and hydrogen (H₂), alongside two different carbon monoxide concentrations.

For a prepared mixture containing a calculated CO concentration of 0.52 vol%, the CO Analyzer measured 0.51 vol%. In a second test containing a calculated 0.10 vol% CO, the analyzer measured 0.09 vol%.

In both tests, the measured CO concentration was within 0.01 percentage points of the calculated concentration in the prepared mixture. At the same time, the mass spectrometer monitored the other gas components.

These results show close agreement between the prepared and measured CO concentrations. They also illustrate how dedicated carbon monoxide analysis can complement multi-component mass spectrometry when researchers analyze complex gas streams.

Carbon monoxide measurement for syngas research

Carbon monoxide and hydrogen are key components in syngas research. Combining the CO Analyzer with mass spectrometry enables dedicated CO quantification alongside simultaneous monitoring of hydrogen, carbon dioxide, methane and other gaseous species.

This approach supports the study of gas composition and changes that occur under different reaction and process conditions.

Multi-species gas analysis for biogas research

The combined system can also support biogas and gas-conversion research, where multiple gaseous components may be present. When carbon monoxide is present or generated, the CO Analyzer provides dedicated CO measurement while the mass spectrometer delivers broader multi-species analysis.

Real-time CO monitoring for catalysis

Carbon monoxide can be an important reactant, intermediate or product in catalysis research. Combining dedicated CO analysis with real-time mass spectrometry allows researchers to monitor changes in gaseous reactants and products as experimental conditions change.

Continuous, integrated carbon monoxide analysis

The CO Analyzer is designed for continuous analysis and is available with measurement ranges from 0–2,000 ppm to 0–100% CO, depending on application requirements.

The instrument can be synchronized with Hiden mass spectrometer software, allowing CO measurements to be acquired and displayed alongside mass spectrometry data. By combining dedicated CO quantification with multi-component mass spectrometry, the analyzer expands the gas analysis options available for complex mixtures across syngas, biogas, catalysis and related applications.

Mass SpectrometryMass spectrometry (MS) is a powerful analytical technique used to identify and quantify molecules based on the mass-to-charge ratio of gas-phase ions. It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS).
