The ProCeas® H₂ Purity is an advanced analytical system that leverages Optical Feedback Cavity Enhanced Absorption Spectroscopy (OFCEAS) - a patented technology developed by AP2e (part of DURAG GROUP) - housed in a compact, integrated cabinet. This laser-based technique offers high accuracy and short response time for trace gas analysis, enabling precise detection of critical impurities in hydrogen streams. The system precisely monitors multi-gas compounds with outstanding precision and long-term stability, without requiring carrier gases or consumables. It ensures compliance with ISO 14687 for PEM fuel cell applications and ISO 19880 for hydrogen quality at distribution and refueling sites. Designed for both on-line and off-line operation, it is perfectly suited for hydrogen production processes (electrolysis, SMR, pyrolysis), as well as research labs, analytical facilities, and fueling stations. Early and accurate detection of trace impurities is essential to protect fuel cell catalysts, maintain hydrogen system efficiency, and prevent long-term degradation of performance and reliability.
