An arrangement for performing chromatography with a mobile phase and a chromatographic bed having a stationary phase is provided. The arrangement includes a support assembly configured to support the stationary phase. The support assembly has a sealed cavity configured so that when the support assembly is supporting the stationary phase a portion of the chromatographic bed and the stationary phase extends into the sealed cavity. The arrangement further includes a bladder having a void defined therein. The bladder is positioned within the sealed cavity. The arrangement also includes a fluid positioned within the void of the bladder so that the bladder is urged toward the stationary phase within the sealed cavity. The arrangement further includes an anode positioned in contact with the mobile phase. The arrangement also includes a cathode positioned in contact with the stationary phase, wherein creating an electrical potential between the anode and the cathode causes the mobile phase to be advanced through the chromatographic bed positioned within the sealed cavity. An associated method is also provided.
提供了一种利用流动相和具有固定相的色谱床进行
色谱分析的装置。该装置包括一个支撑组件,用于支撑固定相。支撑组件具有一个密封腔,当支撑组件支撑固定相时,色谱床和固定相的一部分延伸到密封腔中。该装置还包括一个囊体,囊体上有一个空隙。膀胱位于密封腔内。该装置还包括一个位于膀胱空隙内的流体,使膀胱被推向密封腔内的固定相。该装置还包括一个与流动相接触的阳极。该装置还包括一个与固定相接触的阴极,在阳极和阴极之间产生电势,使流动相通过密封腔内的色谱床。还提供了一种相关的方法。
