An unexpected observation concerning the effect of anionic additives on the retention behavior of basic drugs and peptides in reversed-phase liquid chromatography.
Wang X, Carr PW. Wang X, et al. J Chromatogr A. 2007 Jun 22;1154(1-2):165-73. doi: 10.1016/j.chroma.2007.03.057. Epub 2007 Mar 21. J Chromatogr A. 2007. PMID: 17448482 Free PMC article.
In this work, we measured the magnitude of the retention increase of basic drugs and peptides upon addition of strong inorganic ion pairing anions (e.g. perchlorate) as a function of the volume fraction of modifier in acidic water-acetonitrile mobile phases on two differen …
