Abstract
A chromatography system includes a first chromatography column for receiving and separating a flow stream, a plurality of traps configured to trap a plurality of distinct flow segments exiting the first chromatography column during separation of the flow stream, and a second chromatography column operatively associated with the plurality of traps for receiving and separating the distinct flow segments. The system can include at-column dilution at trapping and separating stages thereof. A chromatography method for operating the chromatographic system includes measuring a plurality of time segments corresponding to a plurality of peaks of a fluid sample flowing through the first chromatographic column, and sequentially fluidly coupling the plurality of distinct flow segments with the corresponding plurality of traps during time segments corresponding to the plurality of peaks.
