Cleaning or Replacing the FID Collecting Electrode

Thermo Scientific
Note For maintaining or replacing any other component not listed in this section, see
Chapter 7, "Detectors Advanced Maintenance."
• "Removing/Replacing a Detector Module"
• "Cleaning or Replacing the FID Jet"
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 or replace the collecting electrode
1. Put the GC in standby condition.
2. Turn the flame off. The fuel gases, hydrogen and air, are automatically closed.
3. Cool the detector to room temperature.
4. Turn the make-up gas off.
Note By pressing the Maintenance button, the GC cool down is automatically
carried out.
5. Power off the GC.
a. Push down the power switch (breaker), located at the back of the instrument, to the
position O.
b. Unplug the power cable from the AC Input connector into the back of the GC and
from the wall outlet.
6. If external modules are present, unplug the power cable from the AC Input connector of
each module, and from the wall outlet.
7. Open the module flap cover.
8. Disconnect the signal, glow-plug, and polarizing cables from their contacts on the cell.
