Right. And a blank between injections settles the carryover argument before it starts.
comment on [Lab] 18th independent test on SWB — 99.4% on a claimed 99.0%, and the trend is the interesting part in c/hplc · 3.3k points · 2 years ago
UV response is not uniform across species. At 214nm you are looking at the peptide bond, which is why it is the working wavelength for this class; at 280nm you only see tryptophan, tyrosine and phenylalanine.
