Portable G20V TDLAS Methane Ethane Detector for Natural Gas Leak Inspection

G20V Portable Methane and Ethane Leak Detector

The G20V is a portable laser gas detection instrument designed for natural gas pipeline inspections and gas leak investigations. By analyzing methane and ethane, it provides additional gas composition information to help operators assess suspected natural gas leaks and distinguish them from other potential methane sources.

Combining TDLAS-based laser sensing with an integrated sampling pump, the G20V supports on-site gas analysis and targeted leak investigation. Its portable design makes it suitable for field technicians working across pipeline networks, gas facilities, and industrial environments.

Dual-Gas Analysis for Natural Gas Identification

Methane can originate from different sources, making it difficult to identify the origin of a suspected leak through methane measurements alone. The G20V analyzes both methane and ethane, providing additional information for evaluating gas composition.

Because ethane is commonly present in natural gas but may be absent or present at different proportions in other methane sources, comparing the two gas measurements can help operators assess whether a suspected emission may be associated with natural gas infrastructure.

This additional compositional information supports more informed leak investigations and helps inspection teams determine where further testing may be necessary.

Sensitive Ethane Detection for Field Investigations

The G20V is designed to detect trace ethane concentrations, supporting investigations where small differences in gas composition matter. Its laser-based measurement technology helps operators identify ethane in sampled gas and review the results alongside methane measurements.

This capability is particularly useful when investigating suspected leaks around gas pipelines, connections, storage facilities, and other natural gas infrastructure where identifying the likely source of an emission is important.

Integrated Pump for Convenient Gas Sampling

The G20V features a built-in gas sampling pump to draw samples into the detection system for analysis. This integrated configuration supports field inspections without requiring a separate external sampling pump for routine operation.

Portable sampling enables technicians to investigate selected locations and collect gas measurements as part of pipeline maintenance, suspected leak checks, and industrial inspection procedures.

TDLAS Technology for Selective Gas Measurement

The G20V uses Tunable Diode Laser Absorption Spectroscopy (TDLAS) to detect target gases through their characteristic optical absorption properties. The system analyzes laser absorption signals to determine the concentrations of the gases being measured.

This selective measurement approach supports methane and ethane analysis and provides useful compositional information for natural gas leak investigations. Combined with its integrated sampling system, the G20V offers a practical solution for on-site gas assessment.

Real-Time Analysis for Faster Inspection Decisions

The G20V provides measurement feedback during gas analysis, allowing operators to review methane and ethane readings during field investigations. Access to both measurements helps inspection teams compare gas composition and prioritize locations requiring further evaluation.

By bringing gas analysis directly to the inspection site, the instrument supports efficient field workflows and reduces reliance on sending every sample away for separate laboratory analysis.

Applications

Natural Gas Pipeline Inspection

Investigate suspected leaks along gas pipelines, service connections, valves, and other associated infrastructure. Methane and ethane analysis provides additional evidence for evaluating potential natural gas leakage.

Gas Storage and Distribution Facilities

Assess gas composition around suitable storage installations, distribution equipment, and pipeline connections during routine inspection and maintenance.

Industrial Leak Investigation

Support gas leak assessments at refineries, chemical plants, gas processing facilities, and other industrial sites where methane and ethane measurements may help identify the source of an emission.

Environmental Methane Monitoring

Assist with investigations at landfill sites, biogas facilities, and other locations where methane emissions may originate from different sources.

Field Gas Composition Analysis

Provide portable, on-site gas measurements for inspection teams evaluating suspected emissions and determining whether additional verification is required.

A Smarter Approach to Natural Gas Leak Identification

The G20V combines portable operation, integrated gas sampling, and methane–ethane analysis in one laser-based detection instrument. By adding gas composition information to conventional methane inspection, it helps operators investigate suspected leaks more effectively and make better-informed decisions about pipeline maintenance and follow-up testing.
