<p>New fixing arrangement for chromatography columns, this arrangement showing first retaining means (13, 14) of the column (1) designed to allow the column's manually quick change without the help of any special tools and facilitating the reuse of the input and output nipples of the column(1); and second means (2b) designed to fix and hermetically sealing the connecting nipple (7) of the capillary. The special setting of the column retaining means allows that a pre-column cartridge (10) is included or not, the fucntion of the cartridge being to extend further the column useful life. The pre-column cartridge coupling arrangement also removes the formation of any dead volumes, which presence is critical to any chromatographic separation, all that happening because of the suppression of the coupling fittings between both components. <IMAGE></p> |
