A community side-effect dataset, with its response rate and biases — setting out what I have, and where I think it stops being reliable.
Posting the method first, because I know what the first three replies will otherwise be.
- Column: C8, 4.6 x 150 mm, 3.5 um
- Mobile phase: 0.1% TFA in water / 0.1% TFA in acetonitrile
- Gradient: 12% to 53% organic over 19 minutes
- Detection: 280 nm
- Injection: 15 uL
- Sample: retatrutide, reconstituted to 0.5 mg/mL, injected within an hour
The main peak integrates at 98.6% of total area. There is a small feature on the trailing edge that I cannot decide is a shoulder or a baseline artefact, and that is what I am actually asking about.
