Abstract
The present invention relates to a device for preventing band broadening and remixing of separated fractions, and associated method, comprising a chromatographic column coupled to a flow selector, such as a rotary valve, wherein said flow selector is connected to the distal end of said column such that the sum of post-column swept volume and post-column dead volume is less than 10 μL. Preferably, the column is directly plugged into the inlet port of the rotary valve and the sample is fractionated at the outlet port.
