ABSTRACT:
Various chemicals such as pharmaceuticals and petrochemicals are chromatographically separated in small quantities using an apparatus comprising a number of serially connected adsorbent-containing chambers. The chambers are linked together with valving necessary to simulate the continuous countercurrent flow of the adsorbent and liquid phases. The apparatus employs three three-port valves per chamber to direct liquid flow. Pressure pairing of the valves and the four major process streams protects product purity.
