G20 Portable TDLAS Methane Ethane Leak Detector with PPB Sensitivity

G20 Portable TDLAS Methane Ethane Leak Detector with PPB Sensitivity

Product Overview

The AiLF Instruments G20 Portable Laser Gas Detector is designed for sensitive natural gas leak detection and gas composition analysis. Combining advanced laser absorption spectroscopy technology with a compact, portable design, the G20 can detect methane, ethane, and water vapor in sampled air, helping operators identify potential gas leaks and distinguish natural gas leakage from other methane sources.

With ethane detection sensitivity reported as low as 0.5 ppb, the G20 provides rapid, high-sensitivity measurements for field inspections. By analyzing methane and ethane concentrations together, the instrument supports more reliable leak identification across natural gas distribution networks, industrial facilities, and environmental monitoring applications.

Key Features and Benefits

1. High-Sensitivity Ethane Detection

The G20 is designed for ppb-level ethane detection, with a reported detection capability as low as 0.5 ppb. This high sensitivity helps identify trace ethane concentrations that may indicate natural gas leakage, supporting early investigation of potential leaks.

2. Methane and Ethane Differentiation

The G20 measures both methane and ethane concentrations, allowing operators to assess gas composition and identify potential natural gas leaks. Comparing the relative concentrations of these gases can help distinguish natural gas emissions from methane sources that contain little or no ethane.

3. Advanced Laser Absorption Spectroscopy

Using advanced laser absorption spectroscopy technology, the G20 provides sensitive gas analysis in a portable instrument. Its optical detection approach supports rapid field measurements of methane and ethane, helping improve the efficiency of natural gas leak surveys.

4. Rapid Detection and Real-Time Monitoring

The G20 delivers timely concentration readings during inspections, enabling operators to investigate suspected leak locations and respond to changing gas levels. Fast measurement supports efficient field workflows and helps reduce unnecessary inspection time.

5. AI-Assisted False Alarm Filtering

The G20 incorporates an AI-based spatiotemporal model for false alarm filtering. By analyzing spatial and temporal patterns, the system is designed to reduce false alarms and improve the correlation between reported alerts and potential leak locations.

6. Portable and Vehicle-Mountable Design

The G20 can be used as a portable detector or mounted on compatible small, slow-moving vehicles, such as electric bicycles, when equipped with the V-Dock. This configuration supports efficient surveys in residential communities, courtyards, and other areas where access by larger inspection vehicles may be limited.

The main unit and docking station feature a snap-fastener connection for convenient assembly and separation, supporting both handheld operation and vehicle-mounted inspections.

7. Flexible Integration with Leak Inspection Systems

When configured with compatible equipment, the G20 can complement the AiLF A20 system for natural gas distribution network inspections. Its portability and gas differentiation capabilities make it useful for last-mile pipeline surveys and targeted leak investigations.

Applications

Natural Gas Pipeline Leak Detection
