Abstract
An improved liquid chromatography column having a horizontal flow of the liquid through the separating medium utilizing an improved fluid distribution system is disclosed. The improved fluid distribution system includes a screen or mesh arrangement, and a thin layer, plate or wafer-like separation medium. The screen or mesh type distribution system enables uniform distribution of the sample or eluting fluid radially over 360.degree. around the periphery of the separating medium bed, thus eliminating the high machining costs and other problems associated with systems employing grooves or passageways type distribution systems. The improved column as a whole may be fabricated so as to be disposable or may be constructed to have an even more simplified fluid distribution arrangement.
