  • Page 21: Hydrogen Safety

    Introduction Hydrogen Safety Hydrogen Safety The use of hydrogen as a GC carrier gas, detector fuel gas, or in the optional WAR N IN G JetClean system, is potentially dangerous. When using hydrogen (H ) as the carrier gas or fuel gas, be aware that WAR N IN G hydrogen gas can flow into the GC oven and create an explosion hazard.

  • Page 22: Hydrogen Accumulation In An Ms

    Introduction Hydrogen accumulation in an MS • Accumulation of hydrogen in the GC oven and subsequent combustion. See your GC documentation and the label on the top edge of the GC oven door. • Accumulation of hydrogen in the MS and subsequent combustion Hydrogen accumulation in an MS The MS cannot detect leaks in inlet or detector gas streams.

  • Page 23: Precautions

    Introduction Precautions Once hydrogen has accumulated in a MS, extreme caution must be used when WAR N IN G removing it. Incorrect startup of a MS filled with hydrogen can cause an explosion. After a power failure, the MS may start up and begin the pumpdown process WAR N IN G by itself.

  • Page 24: Safety And Regulatory Certifications

    Introduction Safety and Regulatory Certifications Operating precautions • Turn off the hydrogen at its source every time you shut down the GC or MS. • Do not use hydrogen as a CC gas. • Turn off the hydrogen at its source every time you vent the MS.
