Agilent 5975 Mass Selective Detector - Hydrogen Safety

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.
