WARNING
EXPLOSION HAZARD! Always use non-flammable liquids, for
example 20% ethanol, to pack the column, to flush solvents out of
the column, and to fill an empty column before filling it with sol-
vents. Otherwise, air might enter the flow path and create an
explosive atmosphere when being mixed with vaporized solvent.
The user is responsible for preparing procedures to make sure that
only nonflammable liquids, for example 20% ethanol, are used for
flushing the column or for filling an empty column before filling it
with solvents.
