Ph of 0.1% tfa
WebI used 0.1% FA before to desalt my peptides using the zip tip, and then both have a comparable pH (0.1% TFA =2.0, 0.1% FA = 2.7). I was wondering is this going to majorly affect my desalting/results? I also read 0.1% FA Is better to use for ESI MS Which our quantification method. 2 1 1 comment Best Add a Comment Pompster • 1 yr. ago You're … WebJun 5, 2015 · Typically, 0.1% trifluoroacetic acid (TFA) is added to both the water and and acetonitrile.
