Clean the
Glass Insert
Glass inserts must be clean and free from sample residue and particulate
matter (such as bits of septum rubber or graphite). Follow these steps to
clean the glass insert of the 1061 Injector.
1
Remove the glass insert. It is safest to cool the injector to 50°C
before removing the insert.
WA R N IN G :
B U R N H A ZA R D
Use care when removing inserts from the injector.
Inserts can be at high temperatures and are likely hot.
Place hot inserts on a clean glass or metal surface only.
2
To clean glass inserts, use one of the following procedures (the
choice of cleaning procedure depends upon the nature of samples
injected):
•
Rinsing the inserts with solvent or soaking the inserts in hot acid.
•
Heating them in a glass annealing oven (to 500°C) or passing
the inserts through the flame of a Bunsen burner.
•
Wash in a 1:1:1 mixture of methanol:methylene chloride:hexane
in an ultrasonic cleaner for 30-60 min, then dry the inserts in an
oven.
