Abstract
A system and process for chromatography that uses a chromatography column to separate components from a sample received into the column in a mobile phase flowstream and places a second chromatography column between a detector and a collection system that compensates the timing of fraction collection for a delay caused by processing the collection signals generated by the detector. The device and process of the preferred and alternative embodiments add a delay into the flowstream of a chromatographic system, such as LC, HPLC, and SFC. Sample fractions are collected from sample component concentration peaks based upon the chromatographic elution of the sample components.
