Clean or Replace the Liner
12. Using tweezers, remove the liner from the bath
and dry it with compressed clean air.
NOTE For trace analysis, you should pre-
treat the liner with a suitable
silylating reagent prior to re-
inserting it into the injector.
PRECAUTIONS
13. Holding the new (or cleaned) liner with
tweezers, place a graphite seal over the liner,
making sure to leave a distance of about 10 mm
between the seal and the liner end.
14. Using tweezers, insert the liner into the injector
and push it gently towards the bottom fitting.
CAUTION Make sure you insert the
bevelled end of the liner
towards the bottom of the
injector.
CAUTION Be careful not to damage the
graphite seal or allow graphite
to entering the liner. Should this
occur, clean the liner with an
inert gas.
