Abstract
A chromatography detection system can handle the flow from a chromatography column. The chromatography detection system has an injection valve and a detector for detecting emissions from a flowing sample. The injection valve has at least one loop and is adapted to connect to the chromatography column. The valve can (a) load the at least one loop independently of the chromatography column in a first mode, and (b) serially connect the least one loop between the chromatography column and the detector in a second mode. Thus, flow from the at least one loop to the detector is driven by eluate from the chromatography column.
