ABSTRACT:
Presented is a universally and quickly applicable mounting apparatus for high pressure liquid chromatography columns, providing for supporting and quickly connecting and disconnecting a chromatography column to a solvent line, with the capability of ensuring leak-proof seals at high pressures, and minimizing or reducing to zero the fluid "dead" volume in the connections. The quick-connect and quick-disconnect mounting apparatus works with either male or female column connection unions of both low dead volume and zero dead volume design, does not require the use of tools, and applies pressure uniformly to the upper and lower seals of the column. The apparatus also provides for mounting a sample injector in close proximity to the column inlet to minimize sample dilution and delay. Additionally, the apparatus provides for the quick mounting, and dismounting, without use of tools, of an auxiliary filter device of relatively low cost in comparison to the cost of the column, thus providing for increased longevity of the primary column at maximum efficiency.
