Cap LC

  1. Click [Configure Ignition Sequence] on the Startup Pane toolbar, and then select [User Tune]. Also turn on [Set as Global Tune] in the User Tune Pane toolbar.
  2. Setup a No Gas tune mode in User tune. Tune it as usual, using peripump as a sample introduction system. 
  3. Select No Gas mode as the Set Base Tune for Startup. For an s-model, select <None> as the Base Cool Tune Mode.
  4. Run EM parameter adjustment, and then run the P/A factor adjustment.
  5. Turn Plasma Off to change the sample introduction system.

    Setup a dedicated nebulizer and spray chamber on the ICP-MS.

  6. Connect Cap LC tubing, and remote cable to ICP-MS. Select [Agilent LC] as the Sample Introduction.
  7. Do not connect the Cap LC column, instead connect the tubing directly to the ICP-MS. Introduce 10ppb tune solution (Li, Co, Y, Ce, Tl ) instead of a moving phase solution. Wait until the solution has been completely substituted.
  8. Ignite the plasma.
  9. Make the following settings in User tune task.

    RF:1550W

    Nebulizer Gas (also called carrier gas): 0.80 l/min

    Dilution gas: 0.25 l/min

  10. Run Custom tune in User tune task.
  11. Adjust the Dilution gas flow rate to maximize the signal.
  12. Click [Startup Configuration] from the [Startup] group in the Task Navigator, and then run Startup tasks except for EM and P/A factors.
  13. Introduce a moving phase to Cap LC. Wait until The solution is completely substituted, and then connect the column.
  14. Create or open a Batch for data acquisition, and then start data acquisition.

 

The above is the tuning procedure for the first use of a Cap-LC connection. From the second time, perform steps 7, 8, 12, 13, and 14. And instead of 12 you can choose to execute Startup tasks at the time of ignition 8. When you need to adjust the EM and P/A factors, you need to perform all of the steps.
