Split/Splitless Injector Maintenance
The S/SL (Split/Splitless) injector will normally be serviced by Thermo Fisher
Scientific authorized technical personnel.
In order to operate at peak performances, the injector requires maintenance from
the user. This maintenance includes:
•
the replacement of the septum
•
the cleaning or replacement of the liner
•
the replacement of the split line tubing
When replacing the septum
The septum should be replaced at least after every 100-200 injections, or every
time a problem related to septum damage or wear occurs (refer to Chapter 19
for more information). It is a good practice to change
the septum with a new one every time the liner is replaced.
CAUTION
The Injector temperature, when high, it makes a prematurely “aging” of the septum.
It is good practice to replace the septum of the S/SL injector every week
independently on the number of injections done.
When cleaning or replacing the liner
The liner must be replaced periodically, depending on the number of injections
performed and the characteristics of the samples injected. Typical symptoms will
indicate that the liner must be replaced (refer to Chapter 19
). The most common is the appearance of tailing peaks in the
chromatogram, particularly for polar compounds.
It is good practice to replace the septum every time the liner is replaced.
