WARNING
Detector disassembly and/or cleaning procedures other than thermal should be performed
only by personnel trained and licensed appropriately to handle radioactive materials. Trace
amounts of radioactive
63
Ni may be removed during other procedures, causing possible
hazardous exposure to b- and x-radiation.
CAUTION
To prevent possible hazardous contamination of the area with radioactive material, the
detector exhaust vent always must be connected to a fume hood or otherwise vented in
compliance with the latest revision of 10 CFR Part 20, or with state regulations with which the
Nuclear Regulatory Commission has entered into an agreement (USA only). For other
countries, consult with the appropriate agency for equivalent requirements.
1 Gather the following:
• Column nut and no-hole ferrule, see “Consumables and Parts for the ECD” on page 174.
• Blanking nut with any column ferrule
2 With the detector oven at normal operating temperatures, show the detector output signal
in Status. Note the value of the Output for later comparison.
a Go to Home > Status listing > +Add.
b
c Select Signal Value for the ECD from the drop-down list.
d Touch Add.
WARNING
Be careful! The oven and/or detector may be hot enough to cause burns. If the detector is
hot, wear gloves to protect your hands.
WARNING
Wear safety glasses to protect your eyes from flying particles while handling, cutting, or
installing glass or fused silica capillary columns. Use care in handling these columns to
prevent puncture wounds.
3 If the column maximum temperature is < 250 °C, remove the column from the detector.
4 If the column is uninstalled, plug the detector connection with the column nut and no-hole
ferrule.
Maintain inert carrier gas flow through the column, or remove the column from the GC.
5 Set the ECD temperature to 350 to 375 °C, the makeup gas flow to 60 mL/min, and the
oven temperature to 250 °C. If the column is uninstalled, leave the oven off to protect the
column.
6 If the column is installed in the ECD, set the oven temperature to 250 °C. If the column is
uninstalled, leave the oven off to protect the column.
7 Allow thermal cleaning to continue for several hours and then cool the system to normal
operating temperatures. The figure below shows detector output during a typical cleaning
cycle.
