Ultra-Pure gases and Hydrogen Production and Storage

Ultra-pure gases such as e.g. N2(99.9999%) or Ar(99.9999%) are essential in microelectronics production and other high-end applications. While these gases seem to be very clean, they still can contain some traces of e.g. water, hydrocarbons or even VOC’s traces from e.g. sealing materials or other leftover impurities from cryogenic systems.

Through various EU-funded projects we have developed state-of-the-art measurements capabilities for trace components measurements in ultra-pure gases. The technique has later been extended to industrial hydrogen process production chain such as e.g. steam methane reforming where hydrogen purity and impurities on-line measurements are in focus for the end user (e.g. for fuel cells applications or e-CH4 synthesis).
