5 Installation Procedure WARNING This procedure explains how to install the transfer line interface accessory on the Agilent 9000 Gas Chromatograph (GC). Read the Agilent Intuvo 9000 Gas Chromatograph Safety Manual before using the GC. The Safety Manual describes precautions to follow when installing and using the GC, as well as important regulatory information. Before proceeding, turn off the column heater and other heated zones, and let them cool down. When they have cooled, turn off any inlet gases at their supply, then power down the GC as directed, and unplug the power cord. WARNING If an MS is installed on the GC, it must be cooled and vented prior to installation of the inlet. Refer to the Operation Manual for the MS for cooldown and venting procedures. WARNING If an MMI inlet is installed on the GC, high pressure or extremely cold gas may be present. Before replacing a cryo valve or connected inlet, run the GC maintenance method, and turn off the cryo line at the source. 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 Ensure you are properly grounded with an ESD wrist strap before continuing. Installation Instructions 5

9 Install the accessory on the GC CAUTION Avoid sharp bends when handling the septum purge tubing assembly. Failure to do so may result in damage to the hardware. 1 The accessory is shipped configured for installation on an S/SL inlet. If the accessory is being installed on an MMI inlet, do the following: a Use a T-20 Torx driver to remove the three screws securing the two spacer blocks to the accessory. See Figure 9. Screws Figure 9 Transfer line interface accessory spacer blocks Spacer blocks b Flip the spacer blocks over, and reinstall them by securing with the three screws. See Figure 10. Spacer blocks Figure 10 Transfer line interface accessory spacer blocks (oriented for MMI installation) Installation Instructions 9

10 2 Carefully unfurl the septum purge tubing to place the transfer line interface accessory into the GC, leaving the looped portion of the tubing coiled. Avoid making any sharp bends. See Figure 11. Turn top insert assembly Looped tubing Carrier gas line EPC module weldment Figure 11 Positioning the transfer line interface accessory in the GC 10 Installation Instructions

11 3 Place the turn top insert portion of the transfer line interface accessory on top of the inlet, taking care to keep it level. When properly positioned, the arm on the transfer line connector is roughly parallel to the front of the GC. A positioning pin on the GC inserts into the accessory heating block to align the accessory. See Figure 12 and Figure 13. Turn top handle Turn top insert assembly Transfer line connector arm Figure 12 Turn top inlet and transfer line heater block installation and alignment Positioning pin Inlet interface PCA Accessory heater cable connector Accessory heating block Figure 13 Uninstalled Installed Turn top inlet and transfer line heater block installation and alignment Installation Instructions 11

12 4 Rotate the yellow turn top handle on the turn top insert assembly to lock it in place. 5 Insert the accessory heater cable into the connector on the inlet interface PCA. The connector is keyed to prevent improper insertion. 6 Use a T-10 Torx driver to tighten the captive screw securing the EPC module weldment to EPC module. See Figure 6 on page 7. 7 Route the carrier gas line out of the rear of the GC. See Figure 11 on page Ensure that the vent tubing within the GC is properly oriented. The looped portion of tubing should reside near the split vent trap. 9 Install the EPC bracket to the GC and use a T-10 Torx driver to secure it with two captive screws. See Figure 5 on page Place a Swagelok fitting on the end of the carrier gas line, and connect it to the Carrier fitting on the back of the Agilent 7697A Headspace Sampler. See Figure 14. Carrier gas tubing Figure 14 Carrier gas connection at 7967A Headspace Sampler 12 Installation Instructions

13 Prepare the transfer line Materials are provided in the ship kit to make connections to 0.53-mm id columns and tubing. If you are using a different transfer line, use the appropriate ferrules (see Table 2). Ensure the flexible metal ferrule dimension matches the transfer line. Cut fused silica, and install the flexible metal ferrules and the transfer line. Table 2 Flexible metal ferrules Description Part number.25 mm flexible metal ferrules, inert G mm flexible metal ferrules, inert G mm flexible metal ferrules, inert G Before performing this procedure, ensure the transfer line is installed in the 6-port valve. Refer to the procedure To Install a Fused Silica Column into the Transfer Line in the Agilent 7697A Headspace Sampler Maintenance Manual. To prepare the GC interface end of the transfer line: 1 Pass the transfer line fused silica tubing through the XLSI transfer line nut, flexible metal ferrule, and ferrule pre-swage tool. See Figure 15. XLSI transfer line nut Flexible metal ferrule Transfer line fused silica tubing Ferrule pre-swage tool Figure 15 Threading the XLSI transfer line nut, ferrule, and ferrule pre-swage tool 2 With the XLSI transfer line nut tight against the transfer line, hold the nut with a 1/4-inch wrench, and thread the ferrule pre-swage tool onto the nut. Installation Instructions 13

14 CAUTION The flexible metal ferrules are delicate. They must not be overtightened. Failure to carefully follow the instructions in the following steps may cause the fused silica tubing to break. 3 Using the 1/4-inch wrench and ferrule pre-swage tool, tighten the nut a little at a time, occasionally checking to see if the ferrule is gripping the tube. 4 When the ferrule just starts to grip, notice the position of the nut and then tighten by turning 45 to 60 degrees of rotation, but no more than 60 degrees (one flat). If you can pull the column free, it is not tight enough. 5 Remove the ferrule pre-swage tool. 6 Using a ceramic column cutter, trim the tubing at the small end of the ferrule, leaving approximately 0.3 mm of tubing extending beyond the ferrule. NOTE The column tubing end cannot extend beyond 0.5 mm from the end of the ferrule. It is important that the ceramic column cutter has one side dedicated to only making contact with the column and the other side dedicated to riding on the edge of the flexible metal ferrule. This preserves the ceramic edge sharpness, which is necessary for making good column cuts. See Figure 16. Figure 16 Ceramic column cutter and ferrule 7 Check the end of the tube with a magnifier. The end of the tube need not be perfectly square, but should not have cracks extending under the ferrule. 14 Installation Instructions

15 Attach the transfer line to the accessory 1 Install the accessory GC top cover, without the accessory inlet cover installed, and secure it by using a T-20 Torx driver to tighten the five captive screws. See Figure 4 on page 6. 2 Unlatch and open the clamp on the transfer line interface accessory. See Figure 17. Transfer line end-cap Clamp XLSI transfer line nut Figure 17 Attaching the transfer line to the GC 3 Carefully place the transfer line end-cap into the clamp on the transfer line interface accessory. The end-cap should lie squarely against the bottom and back surface. 4 Partially latch the clamp, closing it enough to loosely secure the transfer line and end-cap. This provides strain relief, and aligns the end-cap to the heated block portion of the transfer line interface accessory. 5 Carefully thread the XLSI transfer line nut into the transfer line interface accessory fitting while keeping the transfer line end-cap aligned with the fitting. 6 Finger tighten the XLSI transfer line nut on the end of the transfer line, screwing it into the transfer line interface accessory fitting. 7 Completely latch the clamp. 8 Use a 1/4-inch wrench to tighten the XLSI transfer line nut by 1/2 a flat (30 degrees).
