On the day they gave out brains, I was last in line.
Okay, literature gradient conditions say "30% 0.1% TFA/acetonitrile to 40%."
First I leave out the TFA part. (TFA = trifluoroacetic acid)
Then I put in the TFA part, but I put the TFA in acetonitrile. Wrooooooong.
Ok, put TFA into water, like it's supposed to be. Still getting no peaks. WTF.
Then I discovered:
It's 30% WATER/TFA as the starting conditions, not 30% ACETONITRILE
DUMB DUMB DUMBASS
NO WONDER MY PEAKS ARE ROCKETING OFF THE FUCKING COLUMN
dammit.
