Ultra Portable Analyzer for Field Gas Measurement
Measuring gases directly at the source can provide information that may be difficult to obtain from collected samples alone. An Ultraportable Gas Analyzer brings sensitive laser-based measurement into field environments, allowing researchers to investigate gas concentrations where emissions, exchanges or atmospheric changes occur.
The analyzer uses Off-Axis Integrated Cavity Output Spectroscopy (OA-ICOS). A laser passes through an optical cavity containing the gas sample, creating a long effective absorption path that enables selective measurement of target molecules across a broad concentration range.
The platform integrates its optical system, vacuum pump, computer and communication interfaces into a transportable enclosure. AC and DC power options make it suitable for stationary experiments as well as temporary and mobile measurement campaigns.
Different configurations are available according to the gases under investigation, including methane, carbon dioxide, water vapour, ethane and other atmospheric species.
Dutco Tennant LLC supplies gas analysis solutions for environmental research, atmospheric science, energy studies and industrial investigations.
High-Sensitivity Gas Measurement Outside the Laboratory
- OA-ICOS Technology – Uses cavity-enhanced laser absorption to identify and quantify selected gas molecules.
- Fast Gas Exchange – The standard internal pumping arrangement provides an approximately 8-second gas-flow response.
- Integrated Vacuum Pump – Eliminates the need to assemble a separate pumping system for standard measurements.
- Low Power Requirement – Current ultraportable configurations operate at less than 66 W.
- AC & DC Supply – Provides flexibility for laboratory, vehicle and temporary field installations.
- Digital Communication – Measurement and diagnostic information can be transferred to external data systems.
- Rugged Enclosure – Protects the analytical components during transport between measurement locations.
Select the Measurement Around the Target Gas
Rather than using one universal sensor for every application, the platform employs gas-specific optical configurations. This provides researchers with measurement capability matched to the molecules relevant to their study.
- Selective Laser Absorption – Individual molecular absorption characteristics are used to distinguish target gases.
- Broad Measurement Range – Supports studies involving background concentrations as well as elevated gas levels, depending on configuration.
- Water-Vapour Measurement – Selected analyzers measure H₂O alongside the principal target gases.
- Isotope Capability – Specialist configurations extend measurement from concentration to isotopic composition.
- Multi-Gas Options – Selected systems quantify several gases within the same measurement platform.
