3. Remove the GC detector cover, the electronics compartment top and right
side covers, the top back cover and metal RFI shield beneath it, and the back
metal cover. (See the Agilent 6890 Series Gas Chromatograph Operating
Manual.)
4. If a detector is already in the desired detector port for the PFPD, allow the
installed detector to cool; turn off and disconnect all associated gas lines, GC
columns, and electronics; and remove the detector according to the proper
procedure described in the detector’s operating manual.
5. If no detector was previously installed in the preferred detector port, remove
the plastic cutout to the right of the selected port (see Figure 4.1).
6. Remove the circular, metal detector port cover and the circular insulation plug
from the desired mounting position in the GC’s detector area (Figure 4.1). Set
the insulation plug aside for later use.
7. Cut a hole in the top right GC cover as in Figure 4.2.
8. Place a paper towel or tissue paper on the floor of the GC oven. From inside
the oven, cut away the oven insulation covering the detector port. The oven
insulation covering to be cut away is visible though the opening in the metal
oven lining that corresponds to the detector port. After cutting away the
insulation, carefully remove all the insulation material debris and the paper
towel.
9. Cut a hole approximately 1" (25 mm) in diameter in the center of the previ-
ously removed insulation plug in such a way that the center of the hole lines
up with the center of the detection port. After cutting out this hole, replace the
insulation plug in its original position in the detector port.
