NOTE The position of silica wool for being displayed fig. 12.2.1 is for injecting by Auto Injector for AOC-20i.
During manual injections, the needle often goes further int the insert than for injection by an auto injec-
tor. However, ther is no need to change the silica wool position for manual injections. By plasing a sep-
tum on the needle, the length of the needle can be shortened to approximately 40 mm. (Alternatively,
change the position of the silica wool for manual injections.)

Q Packing the silica wool
Pack silica wool flat and evenly without making it too densely pacleed or too fluffy.
Q Notes for servicing the injection unit or replacing columns
Changing the pressure on the inlet abruptly may move the silica wool to a different position.
Make sure not to replace the septum or remove the column when the inlet is under pressure.
