An amino acid mixture consisting of lysine, leucine, and glutamic acid is to be separated ion exchange chromatography using a cation exchange resin at pH 3.5, with tee buffer at the same pH. Which of the amino acids will be retained on the column? What should be done to elute this amino acid from the column?

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
