High-Precision Electrolyser Gas Analysis
Electrolyser systems require accurate and continuous monitoring of gas purity to ensure safe, efficient hydrogen production. The GAS Electrolyser Gas Analyser provides fast, reliable quantification of O₂ in bulk H₂ and H₂ in bulk O₂, supporting both anode and cathode gas monitoring. Using proven GC technology with Thermal Conductivity Detection (TCD), the analyser delivers ppm–% level accuracy with exceptional stability.
Designed for modern hydrogen production environments, the system ensures dependable performance, minimal maintenance, and compliance with ASTM 2504. With an analysis time of under one minute, the analyser supports real-time quality control and high-throughput electrolyser operation.
Applications
- Electrolyser Gas Purity Monitoring
Measure trace oxygen in hydrogen and trace hydrogen in oxygen to ensure safe and efficient electrolyser operation. - Anode and Cathode Stream Analysis
Independently monitor both gas streams or combine them via a shared inlet to assess overall system performance. - Safety Compliance & Leak Detection
Detect ppm-level cross-contamination between H₂ and O₂ streams to prevent hazardous conditions and support safe operation. - Hydrogen Production Quality Assurance
Verify gas purity for downstream industrial, mobility, or energy applications requiring high-grade hydrogen. - Process Optimisation & Performance Tracking
Use fast, repeatable gas measurements to fine-tune electrolyser efficiency and maintain consistent output quality.
Benefits
- Fast Sub-Minute Analysis
<1 minute runtime enables near-real-time monitoring of hydrogen and oxygen purity. - Low ppm Detection Limits
Achieve sensitive detection of impurities using TCD; optional PDD extends performance down to ppb levels. - Robust 24/7 Operation; can handle water
Diaphragm valves and a backflush configuration ensure long-term durability and minimal downtime—ideal for continuous systems and samples saturated with water vapour. - Flexible Configuration Options
Add analysis for nitrogen, argon, water or other components, plus stream selectors or calibration gas inlets. - Fully ASTM-Compliant
Designed according to ASTM 2504 for electrolyser gas purity testing.
