  • Oxygen and toxic gas sensors for medical gas - Nenvitech

    Medical laboratories and hospitals use a range of gases such as enriched oxygen (O2), nitrous oxide (N2O), helium (He), nitrogen (N2) and carbon dioxide (CO2). Many gases used in laboratories have no taste, color or smell, which makes it hard to tell if there is

  • sf6 gas o2 Vacuum Charging - rvcarcare.nl

    sf6 gas o2 Vacuum Charging. Three different gases/gas mixtures were investigated: pure SF6, SF6/O2, and SF6/CHF3. For the first time, a systematic investigation of the etch rate and process anisotropy was performed. It was found that in all cases, the etch rate through the PAA mask was 2 to 3 times lower than that on non-masked areas. [email protected]
