Performing Injectors Routine Maintenance
Maintaining a Split/Splitless Injector with Backflush (SSLBKF)
Thermo Scientific TRACE 1300 and TRACE 1310 Hardware Manual 93
When replacing or removing a glass liner, it might break inside the injector. In this case
the broken parts of the liner must be removed from the injector, including the glass
splinters that might fall into the lower part of the vaporization chamber.
See “Replacing a SSLBKF Broken Liner” on page 97 .
• Replacing the active carbon filters on the carrier gas line and split line
The active carbon filters must be replaced depending on the volume of solvent injected in
the time.
See “Replacing the SSLBKF Carrier and Split Lines Filters” on page 99 .
• Replacing the body head o-rings
The internal (carrier line) and external (purge line) o-rings of the body head must be
replaced when in presence of leaks.
See “Replacing the SSLBKF Body Head O-Rings” on page 100 .
Before maintaining the injector, read the following warning:
Tip It is good practice to replace the septum every time you replace the glass liner.
WARNING The injector fittings could be hot. Carry out all the operations at low
temperature to avoid burns. Therefore, before beginning the sequence, the injector must
be cooled to room temperature.
CAUTION When handling organic solvents you must take precautions to avoid health
hazards.
