This gas analyzer detects traces of H2 in gas mixtures

The ProCeas H2 trace analyzer is said to be the world’s first device capable of measuring H2 via infrared (IR) radiation using optical resonance laser spectroscopy. The system enables direct, continuous measurements of low H2 concentrations (up to 3 parts per million) in Cl2 or other gas mixtures in realtime for control of industrial processes. The system is based on the company’s patented OFCEAS (optical feedback cavity enhanced absorption spectroscopy) technology and low-pressure sampling techniques. OFCEAS is said to be extremely precise for both simple and complex gas mixtures. The optimized optical resonance system produces a very long optical path — 10 km instead of 10 m achieved in conventional Fourier-transform IR and non-dispersive IR technologies — thus enabling sub parts-per-billion detection. — AP2E, Aix-en-Provence, France
