  • Page 6: Plumbing The Purge Gas

    Plumbing the Purge Gas Plumbing the Purge Gas Hydrogen is both a fire and explosion hazard when mixed with air. For this reason, WA R N I N G hydrogen must not be used as the purge gas. For new systems, plumbing is best done by ordering Option 885. The factory will then make the correct purge gas line installation.
  • Page 7 Plumbing the Purge Gas The insulation around the oven is made of refractory ceramic fibers. To avoid inhaling WA R N I N G fiber particles, we recommend the following safety procedures: ventilate your work area; wear long sleeves, gloves, safety glasses, and a disposable dust/mist respirator; dispose of insulation in a sealed plastic bag;...

Route the tubing along the side of the GC to the EPC module.

  • Page 11: Update Auxiliary Epc Controller Firmware

    Update Auxiliary EPC Controller Firmware Update Auxiliary EPC Controller Firmware On new systems, this step is not necessary if Option 885 was ordered (the firmware update N O T E was performed at the factory). However, the update can be repeated without harm. So if there is any uncertainty about the current firmware in the Aux EPC, or if the unit has been used for alternate applications, perform the following procedure.
  • Page 12 Update Auxiliary EPC Controller Firmware 7 Under Devices, select either 6890 or 6850 GC depending on you GC/MSD system.

See Figure a Select the appropriate Aux channel (default: AUX 5). b Select QuickSwap from the PID Settings drop down list. c Click Set to download the new PID constants into the auxiliary EPC module.

  • Page 15: Important Information

    Important Information Important Information The goal of the installation procedure is to prepare a new QuickSwap accessory to run one of the checkout methods on this CD. All of these methods use a 100-µm id restrictor. If you are changing an existing restrictor, or if you prefer to install a different id restrictor, or do not want to use one of the checkout methods supplied, most of the procedure still applies.

  • Page 17 Overview c If using an Aux EPC module, its firmware has been updated. d If necessary, the purge gas controller has been zeroed. e The purge gas supply tubing is routed into the left side of the oven and is terminated with a Swagelok union.

  • Page 18: Confirm That The Gc And Msd Are Ready For Quickswap

    Overview 1. Confirm that the GC and MSD are Ready for QuickSwap 1 Install the GC and the MSD on the laboratory bench and verify performance, as described in their respective manuals. Do not use hydrogen or any other flammable gas as the purge gas, regardless of the WA R N I N G carrier gas choice.

  • Page 19: Select And Install A Restrictor

    Overview 5 For users who plan to use a CI source (CI MSDs only), check the MSD ChemStation version. If using MSD ChemStation version D.01.xx or earlier, install the EI source. Agilent recommends using EI mode for easier installation and leak testing in this case.

  • Page 20: Attach Quickswap To The Msd Transfer Line

    Overview • If using one of the checkout methods provided, review it to verify the flow rate is compatible with your MSD. If not, see the instructions on modifying methods in the Reference Manual. Restrictors are not labeled individually because of their size and because they will be C A U T I O N exposed to high vacuum.
  • Page 21 Overview These fittings use soft metal ferrules and require much less tightening than Swagelok C A U T I O N fittings, with which you are probably more familiar. Follow the tightening instructions very carefully. The restrictors go inside the MSD transfer line and are under high vacuum when the C A U T I O N MSD is pumped down.
  • Page 22 Overview 3 Push Fitting 3 and the restrictor into the lock nut on the MSD transfer line. The fitting will fit inside the lock nut and onto the MSD transfer line. Rotate the plate clockwise. When you feel resistance (from Fitting 3 beginning to compress the soft metal ferrule), turn the plate about 15–30 degrees more.

  • Page 23: Connect The Quickswap Tubing To The Purge Gas Tubing

    Overview 4. Connect the QuickSwap Tubing to the Purge Gas Tubing Hydrogen is both a fire and explosion hazard when mixed with air. For this reason, WA R N I N G hydrogen must not be used as the purge gas. 1 Hold QuickSwap to prevent it from turning and gently unroll the stainless steel tubing enough to reach the end of the purge gas tubing.

  • Page 24: Set And Apply The Purge Gas Pressure

    Overview If not using one of the methods provided, create a new QuickSwap method from the closest checkout method provided, or from an appropriate direct-connection method. In this case, Agilent recommends that you read the Reference Manual and its discussions of methods, restrictor selection, flows and pressures, and temperatures before continuing.

  • Page 25: Prepare The Quickswap End Of The Column

    Overview 9. Prepare the QuickSwap End of the Column Prepare the end of the column fitting with a SilTite fitting. SilTite ferrules are soft metal. These ferrules are less forgiving than capillary column C A U T I O N fittings using graphite/Vespel ferrules, with which you are probably more familiar.
  • Page 26 Overview 3 Find the appropriate SilTite metal ferrule and internal nut from Table Table 2 Available metal ferrule and nut packages Part number Ferrule description Quantity Column id, µm 5188-5361 0.4-mm id pkg of 10 100, 250 5188-5362 0.5-mm id pkg of 10 5188-5383 0.8-mm id...
  • Page 27 Overview 5 Tighten the two nuts together a little at a time until the column is gripped by the ferrule. When the ferrule just begins to grip, notice the position of the nut and then tighten the nuts by turning no more than 60 degrees (one flat).

  • Page 28: Connect The Column To The Inlet And Quickswap

    Overview 10. Connect the Column to the Inlet and QuickSwap Inlet end See the instructions for the inlet you are using in your GC documentation. Much of this manual assumes that you will use a split/splitless inlet. This is the most popular choice. QuickSwap end 1 Insert the end of the column with the swaged ferrule into Fitting 2 on QuickSwap (see...

  • Page 29: Set And Apply The Column Flow

    Overview The MSD ChemStation will not accept an outlet pressure entry greater than 4.0 psig. This does not mean that higher pressures cannot be set for QuickSwap; it is merely a current limitation of the algorithm used to calculate column flow rate. If running in constant flow mode, it is imperative that QuickSwap pressure and column outlet pressure are ≤4.0 psig for accurate flow control.

  • Page 30: Recheck The Quickswap Pressure

    Overview 13. Recheck the QuickSwap Pressure Hydrogen is both a fire and explosion hazard when mixed with air. For this reason, WA R N I N G hydrogen must not be used as the purge gas. With both inlet (carrier) and purge gas pressures on, compare the QuickSwap actual and setpoint pressures.

  • Page 31: Perform Final Leak Test Using The Msd Manual Tune Screen

    Overview 16. Perform Final Leak Test using the MSD Manual Tune Screen The final leak test depends on the type of source installed in the MSD. This leak test consists of spraying the fittings with Freon 134a, a fluorocarbon refrigerant with a prominent fragment at m/z 83, while monitoring selected masses with the MSD.
  • Page 32 Overview Final leak test procedure for EI sources This procedure applies to MSDs with an EI source. For MSDs with a CI source installed, see “Final leak test procedure for CI sources” on page 35. 1 From the Instrument Control screen, select Instrument, then Edit Tune Parameters.
  • Page 33 Overview 3 Select MoreParams, then Tune Params to display the Tune & Display Parameters screen (Figure 14). Figure 14 Tune & Display Parameters 4 Enter the target Masses in the Mass 1, Mass 2, and Mass 3 fields. Use m/z 28 and 32 to monitor air and m/z 83 for a fragment ion of Freon 134a.
  • Page 34 Overview 8 Spray the outside of QuickSwap Fitting 3 (QuickSwap to transfer line) with the Freon 134a spray and observe the screen. If a peak appears at m/z 83 (Figure 15) and then subsides, the fitting is leaking. Tighten QuickSwap slightly and repeat the process until the fittings are leak free.
  • Page 35 Overview Final leak test procedure for CI sources This procedure applies for all MSDs with a CI source installed. This procedure: • Is similar to the procedure used for an EI source (see “Final leak test procedure for EI sources” on page 32) •...
  • Page 36 Overview 5 With the recent, successful CI tune file loaded, select Tune > Create EI Tune File for CI Source. Upon completion, notice that the loaded tune file is now EI-CIsource.u. 6 The manual tune dialog should appear. If not appear, select Parameters > Manual Tune.

  • Page 37: Retune The Msd
