摘要: The possibility to separate charged and uncharged oligomer-like test compounds by high-performance liquid chromatography was investigated, using mixed-mode (reversed-phase/anion-exchange) stationary phases. In order examine this possibility, several columns were evaluated for their reversed-phase, anion-exchange properties neutral model compounds. OmniPac PAX-500, the PRP-X100 mixed-phase PLRP-S/PL-SAX showed promising results separation of real samples.
