Claims12
A chromatograph comprising:
- (a) a bed, wherein said bed:
- (i) has the shape of a right circular cylinder;
- (ii) is comprised of sorbent particles, wherein the mean diameter of said particles is less than 300 micron, and wherein the distribution of said particles within said bed is substantially uniform;
- and
- (iii) has a porosity less than thirty percent;
- wherein the gaps and dead volume in said bed are substantially less than are the gaps and dead volume in a comparable bed formed from the same type of particles, where the comparable bed is formed by dry-packing the particles as a powder;
- and
- (b) means for radially driving a fluid through said bed, said radial driving being substantially uniform.
