Diagnostics (UltiMate 3000 Series)
Outlet Frit Test/Mixer Frit Test

Run this test to check the backpressure caused by the outlet frit/mixer frit of the pump. When the test is run, the backpressure is measured with the fluid components being disconnected.

 Note:

This test uses a very low backpressure, which may lead to a higher pulsation. However, this has no effect on the test result.

How to

  1.  On the first test page, click Next to proceed with the settings required for the test.

     Tip: 

    If the Next button is not active on the first test page, the pump is not connected in Chromeleon or is in Standby mode. Connect the pump to Chromeleon before you continue by selecting the Connected check box. If the pump is in Standby mode, also clear the Standby check box.

  2. Optional: Enter a descriptive text in the Comments field, e.g., the reason why the test is performed.

  3. Prepare the pump. (Grayed test steps can be ignored.)

    1. Reduce the flow rate to 0 ml/min by clicking Execute. This will automatically set the flow to the required value.

    2. Select the eluent channel that contains water.

    3. Purge the pump if required. Click Purge and select the required settings in the Pump Purge dialog box. Click Yes if you have already purged the pump.

    4. Disconnect the pump from other fluidics and close the purge screw. Confirm with Done. Please note: When disconnecting the pump liquid may leak from the outlet valve.

  4. Click Next to start the test.

  5. When the test is complete, reconnect the pump to other fluidics and confirm with Done. Click Next to go to the last wizard page that shows the test result.

  6. To view or print the report with details of the analysis, click Finish and Preview Report. Click Finish to quit the test panel without viewing the report. For information about troubleshooting, click Open Troubleshooting Guide.
