Why is the "Old ID" field in processing method properties in Empower not always populated? - WKB14464

Article number: 14464


  • Empower 3 FR2 and later
  • Processing method properties
  • Old ID


The Old ID column will only be updated when certain fields are updated.

It does not get populated for all changes.

Changes to parameters which do not affect integration (such as components, impurity, peak ratios, default amounts/purity, named groups, timed groups and limits) will not populate the old ID column.

Changes which affect the integration (such as peak width, threshold, etc.) will  populate the old ID column.
