SAEULENCHROMATOGRAPH UND VERFAHREN ZU DESSEN BETRIEB

摘要

A chromatography column is formed of a number of hollow segments (12) which are positioned one on top of the other through their flat-ground faces and are pressed together by a cap nut (4) disposed on the upper part of a steel housing (1). A base segment (9) is supported on a base by feet 10 and is provided with a solvent-permeable glass frit (11). The substance to be investigated is placed above the glass frit (11) in the base segment (9) and carried upwards into the stationary phase surrounded by the hollow segments (12) by the solvent entering between the feet (10). When the chromatographic separation is complete, the column formed by the hollow segments (12) is disassembled, and the substance components present in the individual hollow segments can be analyzed further. <IMAGE>
