Abstract
A method of separating a liquid sample containing viral vectors includes flowing the liquid sample into an anion exchange column. A first viral vector contains a targeted genetic material and a second viral vector contains essentially no genetic material or a non-targeted genetic material, wherein the targeted genetic material is different than the non-targeted genetic material. A mobile phase can be flowed into the anion exchange column, wherein the mobile phase includes a buffer solution A and a buffer solution B. The buffer solutions A and B both include volatile buffer salts. The first viral vector and the second viral vector can be separated so that the first viral vector and the second viral vector elute off the anion exchange column at different times and then be detected.
