    • The present invention provides an apparatus and a method wherein the movement of analytes on a chromatographic separation column is controlled by the manipulation of isocratic and gradient flow. Such manipulation allows for a distinct set of analytes to be eluted from the chromatography column and delivered downstream for further separation and/or processing while the remainder of the sample remains in a “holding pattern” on the chromatography column. As such, the present invention allows for a small portion of the sample to be processed downstream of the column while substantially eliminating undesirable isocratic elution from the column during such downstream processing. Once the downstream processing has been completed, the column of the present invention elutes a second distinct analyte and the remainder of the sample is maintained in a holding pattern. The process may be repeated until the entire sample has been eluted from the chromatography column.
    • 本发明提供了一种装置和方法,其中分析物在色谱分离柱上的移动通过等度梯度流的操纵来控制。 这样的操作允许从色谱柱洗脱出一组不同的分析物,并在下游进行进一步分离和/或处理,同时样品的其余部分保留在色谱柱上的“保持模式”中。 因此,本发明允许样品的一小部分在柱下游进行处理,同时基本上消除了在这种下游处理期间从柱中不期望的等度洗脱。 一旦下游处理已经完成,本发明的色谱柱洗脱第二种不同的分析物,并且样品的其余部分保持在保持图案中。 可以重复该过程,直到整个样品已经从色谱柱洗脱出来。
