comment on [Question] is 94.2% actually fine or am I being sold a rounding error in c/hplc · 51 points · 2 years ago
Correction: that is a tailing factor, not a plate count. Different diagnostics for different problems.
comment on chromatogram is the most under-discussed thing on this board in c/hplc · 32 points · 2 years ago

Minimum order and lead time — did they quote both up front?

Push back: a longer run is not automatically better resolution. You are trading peak width for time and the ratio is what matters.

A shoulder that does not baseline-resolve cannot be quantified honestly. You can report it as an unresolved shoulder, which is useful information, or you can develop the method until it resolves.
