Agilent 5975 Mass Selective Detector - Hydrogen Safety

Version 1

    Hydrogen is a commonly used GC carrier gas. Hydrogen is potentially explosive and has other dangerous characteristics.

    • Hydrogen is combustible over a wide range of concentrations. At atmospheric pressure, hydrogen is combustible at concentrations from 4% to 74.2% by volume.

    • Hydrogen has the highest burning velocity of any gas.

    • Hydrogen has a very low ignition energy.

    • Hydrogen that is allowed to expand rapidly from high pressure can self-ignite.

    • Hydrogen burns with a nonluminous flame which can be invisible under bright light.
