PRODUCT COLLECTION
Gas Analyser & Gas Chromatography (GC)
Understand your gas quality, composition and energy content. Explore online monitoring and analytical systems for reliable measurement and informed process control.
Online Gas Analyser
Continuous, real-time gas quality monitoring

An online gas analyser continuously measures selected gas parameters, helping operators monitor fuel quality, identify process deviations and support safe combustion. The instrument is configured around the gases and operating conditions that matter to your process.
Key features
- Continuous monitoring with fast response
- High measurement accuracy and repeatability
- Low-maintenance options for continuous industrial operation
- Digital communication for SCADA and DCS integration
- Rugged industrial construction
Measured gases, response time and accuracy must be confirmed against the selected analyser model. The pictured instrument is a reference, not a specification for every listed parameter.
Parameters available by configuration
- Oxygen (O₂)
- Carbon dioxide (CO₂)
- Carbon monoxide (CO)
- Methane (CH₄)
- Hydrogen sulfide (H₂S)
- Moisture and other process gases
Applications
- Industrial manufacturing
- PRMS
- Boiler and furnace combustion monitoring
- Biogas and CNG plants
- Petrochemical and chemical industries
- Environmental and emissions monitoring
Gas Chromatograph (GC)
Gas composition analysis and calculated gas properties

A gas chromatograph separates and quantifies individual components of Natural Gas. The resulting composition data supports the calculation of energy content and gas properties used in custody transfer, fiscal metering, billing and process control.
Key features
- Automatic gas-composition analysis
- Calculation of energy content and gas properties
- Continuous online operation
- Configurations for fiscal and custody-transfer applications
- Integration with SCADA, PLC and flow computers, as configured
Component coverage and calculated properties depend on the instrument and configuration. Confirm the required analysis scope when selecting a system.
Typical components measured
- Methane (CH₄)
- Ethane (C₂H₆)
- Propane (C₃H₈)
- Iso-butane and normal butane
- Pentanes and higher hydrocarbons
- Nitrogen (N₂)
- Carbon dioxide (CO₂)
Calculated gas properties
- Higher Heating Value (HHV)
- Lower Heating Value (LHV)
- Gross Calorific Value (GCV)
- Relative density / specific gravity
- Compressibility factor (Z-factor)
- Molecular weight
- Wobbe Index
Applications
- City Gas Distribution (CGD)
- Natural gas transmission
- LNG and CNG facilities
- PRMS
- Custody-transfer stations
- Refineries and petrochemical plants
- Industrial fuel-gas monitoring
