a warm transit can put a visible degradant peak

can you tell a dimer from the chromatogram alone

if the number you are staring at is a third of what you expected, do the charge state arithmetic before you panic

do you trust an area percent from a shallow gradient

update from 8 months ago: switched to asking for the chromatogram rather than the number and it changed everything

show me the spectrum

214nm sees the amide backbone so it sees everything. 280 only sees aromatics

how would a truncation sequence show up

integration choices move the number by a few tenths easily. that is most of your inter-lab variance

a shoulder on a peak is information, and usually bad information
