- USP tailing is missing for a peak with shoulder on right-hand side
- Peak code is S06
- Empower 3
S06 code means there is a problem calculating peak width at 5% height (which is needed for USP tailing factor).
FIX or WORKAROUND
1. Try exponential and tangential non-classic front skim.
2. If that does not work, optimize the method for better separation.
