Bob, here is an easy method that I use.
Dissolve the peptide in 100 mM HCl. Wait ~1 minute. Freeze in liquid N2. Vacuum Dry. >95% TFA is removed.

Hi,
I know that removing TFA from peptide has been discussed before but I
cannot find my file. I need a good and convenient method for removing TFAfrom peptide after c-18 column. Thanks.
Bob
