Cleaning the HeS-S/SL Injector Body
256 TRACE 1600/1610 Hardware Manual
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.
Note Some of the cleaning procedures in this section require the use of methanol.
If methanol is unavailable or prohibited, substitute LCMS-grade or GC-grade ethanol
or isopropyl alcohol. Do not use denatured ethanol as it may contain impurities that
contaminate the GC-MS system.
 To clean the Instant Connect Helium Saver Injector Module injector body
Materials needed
Ultrasonic cleaning bath
Methanol/acetone mixture 1:1
GC-grade methanol
Methylene chloride
Hexane
T20 Torxhead screwdriver
Forceps or tweezers
1. Put the GC in standby condition.
2. Cool the GC oven, injector, transfer line, and ion source.
Note By pressing the Maintenance button, the GC cool down is automatically
carried out.
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
a. Unscrew the septum cap of the injector.
b. Unscrew the ring nut.
c. Remove the septum holder/liner cap with septum from the injector body head.
7. Remove the liner. See
a. Use tweezers to remove the liner with the liner seal from the injector.
8. Remove the analytical column.
