Cleaning the HeS-S/SL Injector Body
Over time, contamination of the Instant Connect Helium Saver Injector Module
will occur
due to the deposition of cored septum particles or other material not captured by the glass
wool of the injection port liner. In this case, the injector insert should be removed and cleaned
according to the following procedure.
To clean the Instant Connect Helium Saver Injector Module injector body
1. Put the GC in standby condition.
2. Cool the GC oven, injector, transfer line, and ion source.
3. Vent the mass spectrometer and set the inlet flow rate (nitrogen) to
Off
. Keep the helium
enabled and pressurized as usual.
4. Put the autosampler away if present.
5. Open the module flap covers.
6. Remove the top parts of the injector. See
