Webba slurry tank when packing chromatography columns. The capability of the mixing system to keep the chromatography resin in suspension and the possibility to integrate the system in column packing were studied. Further, an evaluation of the effect of the integrated, disposable mixer bag impeller on chromatography resin particles was performed. WebbThere are many different causes to “fronting” or “tailing” peaks, but most can be easily remedied. For example, fronting peaks are often caused by column overload or overpacking. Similarly, tailing peaks can be caused by underpacking, or by having a sample that is too viscous.
