How to determine unretained compound from chromatogram
« on: October 19, 2012, 11:26:52 AM »
From reading my text and the web I'm not 100% clear on how to see what compound is unretained from looking at a chromatogram. Is it always the peak with the smallest retention time?

I'll see images like the one below and that's what I'm led to believe...

Not necessarily.  But this is a good picture that you've found.  Have you learned anything else from it?  What do V0 and T0 stand for?  And more important than the name, what do they mean?
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.
