PROCEDURE

1. Open the "Components" tab on the Processing Method Editor screen.

ADDITIONAL INFORMATION

From Empower 3 FR2, it is possible to match components by relative retention time (RRT).
If there is a shift in the absolute retention time, you can save the trouble of manually correcting the retention time by setting the match criteria using RRT.
The RRT value is the value calculated by "Peak retention time / RT reference peak retention time".
