ABSTRACT:
An apparatus and method for separating and collecting chromatographic samples in which three separate chromatographic columns are cycled through an elution mode, an elevated temperature back-flush mode, and a cooling back-flush mode in continuous repetition so that at any one time one of the columns is in an elution mode, another of the columns is in elevated temperature back-flush mode, and the remaining column is in cooling back-flush mode.
