ABSTRACT:
This invention relates to high pressure liquid chromatography and to chromatographic columns employed therein. These columns may be modularly modified as to length and/or internal diameter and may contain other components in the modular system, for example, column sections, adapters and cone adapters, for joining column sections of different internal diameters, and end plate units for funnelling in or discharging out fluids; said end caps or lids, with or without funnel shaped means, for facilitating the liquid entrance or exit; and porous frits, with or without handles, all used in conjunction with the column sections to facilitate their usage for performance of specific chromatographic functions. The column sections have terminal flange-like means for accommodating the joining together for formations of a system suitable for high pressure liquid chromatography of the preparative or semi-preparative type.
