Abstract
Methods and devices are disclosed for a separation device including a sintered polymeric monolith having polymeric microparticulate solids with a pore size from about 0.5 to about 8 microns, a porosity between about 50 percent to about 80 percent and a chromatographic uniformity characterized by an HETP (height equivalent of a theoretical plate) less than about 100 microns.
Claims14
A monolithic chromatographic microporous substrate comprising a sintered microparticulate solid forming the monolithic chromatographic substrate having an average pore diameter from about 0.5 μm to about 10 μm, a porosity of about 50 percent to about 80 percent and a thickness greater than 1.0 mm;
- and
- wherein the monolithic microporous substrate has a compressive modulus greater than about 50 psi (0.345 MPa).
