Separate the MS from the GC
If using an 8890 or 7890 GC see “Separate the MS and the 8890 or 7890 GC” below.
If using a 9000 GC see “Separate the MS and the 9000 GC” on page 5.
Separate the MS and the 8890 or 7890 GC
Materials needed
•T-20 Torx drivers
•Ferrule, blank (5181-3308)
•Interface column nut (05988-20066)
•Wrench, open-end, 1/4-inch × 5/16-inch (8710-0510)
•Gloves, clean, lint-free (Large 8650-0030) (Small 8650-0029)
Procedure
1Vent the MS. Refer to the Agilent 7000/7010 Series TQ GC/MS Operating Manual.
2Turn off the GC and MS and remove their power cables from the building supply mains.
Remove the capillary column from the GC/MS interface.
3Place a column nut with a blank ferrule on the end of the interface. This will help keep
contamination out of the MS. The foreline pump may be located on the floor or on the lab
table next to or behind the MS,. Move it as needed to provide slack in the tubing and cables.
4Move the MS away from the GC until you have access to the GC/MS interface cable. See
Figure 2 on page 5.
WARNING Ensure the GC/MS interface and the analyzer zones are cool (below 100 °C) before you
vent the MS. A temperature of 100 °C is hot enough to burn skin; always wear cloth gloves
when handling analyzer parts.
WARNING Ensure the GC/MS interface and GC oven have cooled before you remove the column.
WARNING If you are using hydrogen as a carrier gas or for a system with JetClean installed, the
carrier gas flow and JetClean hydrogen supply shutoff valves must be closed before
turning off the MS power. If the foreline pump is off, hydrogen will accumulate in the MS
and an explosion may occur. Before operating the MS with hydrogen carrier gas read the
hydrogen safety information. (See Hydrogen Safety on page 16.)
CAUTION Ensure the GC oven and the GC/MS interface are cool before turning off carrier gas flow.

G7050A - Reference Compound Introduction Valve 5
5Disconnect the GC/MS interface cable. If the MS needs to be moved a significant distance
from the GC, also disconnect the APG cable and the LVDS cable if used.
Separate the MS and the 9000 GC
Materials needed
•Screwdriver, T-20 Torx
•Ferrule, blank (5181-3308)
•MS transfer line plug (G4590-60250)
•Gloves, white, nylon, clean, lint-free (Large 8650-0030) (Small 8650-0029)
Figure 2. Separating/connecting the MS and 8890/7890 GC
WARNING Ensure the GC/MS interface and the analyzer zones are cool (below 100 °C) before you
vent the MS and remove the 9000 GC/MS Tail. A temperature of 100 °C is hot enough to
burn skin; always wear cloth gloves when handling analyzer parts.
WARNING If you are using hydrogen as a carrier gas or for a system with JetClean installed, the
carrier gas flow and JetClean hydrogen supply shutoff valves must be closed before
turning off the MS power. If the foreline pump is off, hydrogen will accumulate in the MS
and an explosion may occur. Before operating the MS with hydrogen carrier gas read the
hydrogen safety information.
CAUTION Ensure the GC oven and the GC/MS interface are cool before turning off carrier gas flow.

6 G7050A - Reference Compound Introduction Valve
Procedure
1Vent the MS. Refer to the Agilent 7000/7010 Series TQ GC/MS Operating Manual.
2Remove the 9000 GC/MS Tail. Refer to the Agilent 7000/7010 Series TQ GC/MS
Operating Manual.
3Verify that the GC and MS are turned off and that their power cables are unplugged from
the building supply mains.
4Using a T-20 Torx screwdriver, loosen the lock plate by turning the lock plate screw
clockwise.
5The foreline pump may be located on the floor, on the lab bench next to or behind the MS.
Move it as needed to provide slack in the tubing and cables.
6Slide the MS backwards, and then away from the GC until you have access to the GC/MS
cables. (See Figure 3 on page 6.)
7Disconnect the GC/MS interface cables. Disconnecting the cable with the GC on can cause
a fault condition. If the MS needs to be moved a significant distance from the GC, also
disconnect the APG cable and the LVDS cable if used.
8Install an MS transfer line plug and blank ferrule on the end of the GC/MS interface. This
will help keep contamination out of the MS.

Materials needed
•Voltage divider board (Figure 1 item 6)
•Aluminum mounting block for voltage divider board (Figure 1 item 5)
•Two screws (Figure 1 item 4)
Procedure
1Use a T-20 screwdriver to remove the one or two screws, depending on MS model,
attaching the sheet metal baffle to the e-module.
2If your MS model includes a LED, remove the LED cable from the plastic holder.
Figure 7. Remove screws from the metal baffle

3Use a screwdriver to pry out the top right corner of the sheet metal baffle and remove it
from the MS.
4Align the screw holes in the PCA voltage divider board (Figure 1 item 6) and Aluminum
mounting block (Figure 1 item 5), with the tapped screw holes in the front electronics
module frame. Use a T20 driver to attach this PCA board and mounting block using two
screws (Figure 1 item 4) threaded into the frame (arrows).

Install the Reference Compound Valve
Materials needed
•Screwdriver, Torx T-20, Flathead
•Reference compound solenoid valve (Figure 1, item 3)
•Two T-20 screws for mounting reference valve (Figure 1, item 9)
•Dual Adapter Assembly (Figure 1, item 8)
Procedure
1Use a T-20 screwdriver to remove the CAL valve from the analyzer housing. Keep the valve
attached to its control wiring.
2Fill the reference valve vial with PFTBA (Table 1, item 10). See “Maintenance” on page 34.
3Replace the valve O-ring in the Analyzer manifold with a new one (Figure 1, item 7).
4Install two O-rings (Figure 1, item 7) into the Dual Adapter Assembly (Figure 1, item 8).
5Position the Dual Adapter Assembly as shown, with the through holes positioned over the
original CAL valve screw holes on the analyzer.
Figure 11. Remove the CAL valve
Figure 12. Position the Dual Adapter Assembly over the original CAL valve screw holes

12 G7050A - Reference Compound Introduction Valve
6Position the Reference Compound Valve (Figure 1, Item 3) over the rear Dual Adapter
Assembly and drop the two long screws (Figure 1, item 9) through the Reference
Compound Valve and Dual Adapter Assembly into the threaded holes in the Analyzer
manifold.
7Use a T-20 driver to secure the Dual Adapter Assembly and Reference Compound Valve to
the analyzer chamber using the two screws.
8Use a T-20 screwdriver to attach the original CAL valve to the front inlet position of the Dual
Adapter Assembly using the two original screws removed in step 1.
If the CAL valve can’t reach its new mounting location due to the length of its control wire,
you must reposition this wiring run so that the CAL valve can be mounted.If equipped, you
must remove the CI or JetClean Flow control system cover to access this CAL valve wiring.
Use a T-20 driver to remove the screw on the rear of this cover and then lift the cover off.
9If you removed the Flow control system cover, replace it after rerouting the CAL valve
wiring and mounting the CAL valve.
10 Route the Reference Compound Valve wiring through the opening slot shown down to the
base of the MS. Route the wiring so that it does not touch the GCMS interface heated zone
cover.
