Dual heated getter technology

It’s well-known in the field that traditional heated getter purifiers release trace amounts of H2 due to both hydrocarbon cracking and the metal being processed at high temperatures. Our proprietary dual-stage purification design unlocks a better purification process and superior performance. With a second vessel operating at a lower temperature, the H2 released by the first vessel is reduced to below 1 ppb.

  • < 1 ppb purity
  • No H2 release


End-of-life detection technology

Based on a pulse discharge optical feedback detector (PDOFD), our purifier’s innovative end of-life technology boasts the dual use of a feedback system comprising a low-cost optical measurement device and pulse discharge generator. The result is a unique detector that monitors gas quality and provides diagnostics and alarms, all in real time.
