Possible cause

Solution

Background not suppressed by suppressor

Verify that the suppressor is turned on and that the current is set to the correct value. For additional troubleshooting guidance, refer to the suppressor manual.

Sample concentration too high

Dilute the sample (see Dilute samples).

Wrong eluent

Check the column manual to verify that you are using the correct eluent for your application.

Background conductivity not offset from conductivity reading

Procedure

  1. Before making an injection, allow the background conductivity to equilibrate. Then, select Autozero on the Inuvion ePanel.
  2. If the problem persists, it may indicate a leak in the conductivity detector. Contact Thermo Fisher Scientific Technical Support for assistance.
