Abstract
A liquid chromatography system and a method of utilizing the same, comprising a plurality of separated-component vessels for collecting components eluted in a separation column, a flowing system conduit for component extraction through which the components separated in the separation column are individually delivered to the separated-component vessels. The system further comprises a flowing system conduit for sample introduction through which any of the separated components collected in the plurality of separated-component vessels is selectively drawn from its vessel and introduced to the upstream side of the separation column. The present invention allows a plurality of components in a sample of a mixture to be individual collected, and also allows any of the collected components to be re-separated selectively and automatically.
