Hydrogen Purity Analyzers

HEMS - Hydrogen Purity Analyzer
The Power+Energy HEMS™ series of Hydrogen Purity Analyzers are full spectrum instruments with limits of detection per impurity of < 1 ppt*. The analyzer is self-calibrating and, with a short analytical cycle time, can be used as an on-line impurity monitor. The compact package and automatic operation make it easy to use for quick sample verification at multiple points.

The HEMS (hydrogen elimination mass spectrometer) analyzer uses P+E’s patented palladium diffusion technology combined with advanced quadrupole mass spectrometry to achieve parts-per-trillion resolution.

Compared to other analyzers, HEMS offers detection of the broadest range of impurities in a compact enclosure with automated operation at an affordable cost.  We offer two versions of hydrogen analyzers:

  • HEMS-T with part-per-trillion detection levels
  • HEMS-M with sub-part-per-million detection levels
