The GAS Battery Swelling Gas Analyser provides a fast and highly detailed analytical solution for monitoring gases generated inside lithium-ion batteries during charge and discharge cycles. Gas evolution within a battery can indicate degradation mechanisms, electrolyte decomposition, safety hazards, and changes in electrochemical performance. By accurately characterising these gases, manufacturers and researchers can gain valuable insights into battery health, lifespan, and failure modes.
The analyser utilizes a three-channel gas chromatography configuration consisting of two Thermal Conductivity Detector (TCD) channels for permanent gases and one Flame Ionisation Detector (FID) channel for hydrocarbon analysis. The FID channel operates with a programmable oven, enabling detailed separation and identification of hydrocarbons from C₁ to C₆, with optional extension up to C₁₀. This configuration provides a comprehensive gas profile covering both permanent gases and volatile organic compounds generated during battery operation.
To address the challenge of limited gas volumes available from battery swelling tests, the analyser incorporates an advanced vacuum sampling system. The sample loop is evacuated before sampling, allowing direct gas extraction from battery cells or syringe injection while minimizing sample consumption and preventing cross-contamination. As a result, only 1–2 ml of gas sample is required for a complete analysis.
The system is available with manual syringe injection or an optional syringe autosampler for automated high-throughput testing environments. Combined with Chromeleon CDS software, programmable temperature control, and robust diaphragm valve technology, the analyser delivers reliable, repeatable, and efficient operation for battery research laboratories, quality assurance facilities, and manufacturing environments.
