Preparative LC strategies include gathering fractionated eluent into discrete sample containers to isolate a number of analytes so that you can purify major elements or isolate impurities for more investigations.
Resolute® BioSC Pilot is actually a multi-phase chromatography system that could repeatedly run three chromatography separations (in batch or multi-column method), like viral inactivation and in-line buffer preparing. The chaining of multiple device operations together results in a compact and intensified procedure.
