How to use peak labeling options in Review and the Report Method - WKB50372

Article number: 50372

OBJECTIVE or GOAL

Have you ever had the need to label your peaks with something other than peak name and retention time?

  • Prior to Empower 3 FR3, the choices for labeling peaks were:
  • Peak name or library match name (if you were doing PDA or MS Library searching);
  • Retention time or scan number (if you were working with MS data);
  • Or you could opt for labeling the peaks with peak labels as defined in the processing method.
  • Working with Empower 3 FR3, we can label each peak with up to three different fields including custom fields and assigned mass if we are working with the ACQUITY QDa Detector.

ENVIRONMENT

  • Empower
