CAUSE

In the Tune page, the setting for desolvation temperature is different in positive and negative modes, causing problems when using positive/negative switching in the acquisition method.

FIX or WORKAROUND

  1. Open the Tune page and ensure that the desolvation temperature setting is the same for positive and negative modes. (Also verify that the source temperature and gas flow settings are the same in both modes.)
  2. Save the Tune page.
