WARNING
Inspect the column before start and replace any damaged parts,
e.g. tubing, connectors or O-rings.
CAUTION
Remove any spillage on the floor immediately to minimize the risk
for slipping accidents.
CAUTION
Thoroughly check the glass column tube to ensure that it is not
cracked or has been severely scratched. Pay extra attention to the
end parts of the column tube.
Perform a leakage test at the start of the process. This will make it possible to
detect leakage at an early stage with minimized consequences and the risk
for potential leakage of hazardous liquids is diminished.
Before packing the column, pump 1.0 M NaOH through the column, empty the
column, and then pump, for example purified water through the column to
make sure that all inner surfaces are clean.
The adapter rod attachment to the adapter may loosen after a period of use.
The tightness shall be checked at regular intervals and be retightened when
appropriate (Servicing the adapter rod, adapter tubing and top plate (stainless
steel bed support), on page 119).
