ABSTRACT:
An analyzer system for automatic column chromatography, and method for its use, includes an array of chromatograph columns and multi-cell cuvettes associated with each column. Chromatographic separation takes place under a constant, low fluid pressure. A pressure system distributes air to each column during chromatographic separation but prevents leakage of air if the column array is partially empty. The multi-cell cuvette collects and separates the eluates associated with a single column. The system provides for automatic removal of caps from the bottoms of the chromatograph columns and provides for automatic optical density reading.
