WARNING

If you are using hydrogen as a carrier gas, the carrier gas flow must be off

before turning off the MSD power. If the foreline pump is off, hydrogen will

accumulate in the MSD and an explosion may occur. Read “Hydrogen

Safety” on page 19 before operating the MSD with hydrogen carrier gas.

CAUTION

Be sure the GC oven and the GC/MSD interface are cool before turning off

carrier gas flow to prevent damage to the column.
