Installation Instructions
5
Installation Procedure
This procedure explains how to install the Side-Mounted Electron Capture
Detector (
μ
ECD) accessory on the Agilent 7890B Gas Chromatograph (GC).
Prepare the GC
1
If the GC is connected to a mass spectrometer (MS), vent the MS and shut it
down. Refer to the MS Operation manual.
2
If a headspace sampler (HS) is installed to a GC inlet, disconnect it. Refer to
the HS documentation.
3
Set the GC oven temperature to 40 °C. Turn off the inlet, detector, valve
box, and other heaters.
4
When the oven cools, turn off the GC and unplug the power cord.
5
Allow time for the detector(s) and other heated zones to cool.
6
Remove the pneumatics cover. Two large buttons on each side of the GC
secure the cover to the detector frame. Press both buttons and lift the cover
off.
WARNING
Refer to the Safety Manual that came with your Agilent 7890B Gas
Chromatograph for hazards that may exist when maintaining your instrument.
WARNING
All versions of µECD cells contain radioactive material. Exposure to radioactive
material is hazardous to human health. Under no circumstances should an µECD
cell be disassembled, as this is in violation of the General License agreement.
µECDs must be returned to a licensed facility. Agilent will accept only µECDs
manufactured by either Hewlett-Packard or Agilent Technologies, Inc.
WARNING
Before proceeding, turn off the column heater and other heated zones and let
them cool down. When they have cooled, turn off any detector gases at their
supply, then turn off the main power switch and unplug the power cord.
CAUTION
Always allow time for the column heater and other heated zones, to cool before
turning off the gas supplies. Failure to allow cooling may damage the flow path.
CAUTION
Make sure you are properly grounded with an ESD wrist strap before continuing.
