For laboratory and scientific needs, hydrogen is used as an ultra high purity fuel and reducing agent. HOGEN® hydrogen generation systems are well-suited to provide ultra high purity hydrogen as a carrier gas with consistent composition and predictable low levels of oxygen and nitrogen. HOGEN® GC hydrogen generators are a simpler, less expensive, and less complex approach to supplying hydrogen for laboratory and scientific applications. For larger labs, HOGEN® S Series 20 and 40 hydrogen generation systems can supply carrier and fuel gas to up to 200 gas chromatographs.
