Claims9
A replaceable, radial-flow chromatographic diskette comprising at least two chromatographic beds, a first said bed and a second said bed:
- (a) wherein each of said beds has the shape of a right circular cylinder having a width substantially greater than its height;
- (b) wherein each of said beds comprises sorbent particles having a mean diameter less than 300 micron;
- (c) wherein the distribution of the particles within each of said beds is substantially uniform;
- (d) wherein each of said beds has a porosity less than thirty percent;
- e) wherein said diskette further comprises a plate in the shape of a right circular cylinder adjacent both the first said bed and the second said bed, which plate separates said first and second beds;
- f) wherein the axes of symmetry of the first said bed, the second said bed, and said plate are collinear;
- and
- g) wherein said diskette further comprises means for transporting a fluid from said first bed to said second bed, said transporting means comprising said plate, wherein said plate has grooves fluidly connecting said first and second beds.
