Abstract: This invention relates to advanced composite filtration media comprising (i) a functional filtration component and (ii) a matrix component, wherein said matrix component has a softening point temperature less than the softening point temperature of said functional filtration component, and wherein said functional filtration component is intimately bound to said matrix component; and methods for preparing and using same. More particularly, this invention pertains to advanced composite filter media and advanced composite filter media products comprised of a functional filtration component, such as a biogenic silica product (e.g., diatomite) or a natural glass product (e.g., expanded perlite) which bears a distinguishing porous and intricate structure suitable for filtration, which is thermally sintered to a matrix component, such as an engineering polymer (e.g., glasses, crystalline minerals, thermoplastics, and metals) that has a softening temperature below that of the functional filtration component. The advanced composite filtration media of the present invention offer unique properties such as increased permeability, low centrifuged wet density, low cristobalite content, and uniquely shaped particles (e.g., fibers).

Abstract: A silica glass filter comprises a porous support body composed of amorphous silica particles as a porous sintered body and having a purity of 99.9% or more and containing 150 ppm or less in total of impurities including alkali, alkali metal, heavy metal and/or elements of III B group, and a filtration layer formed on the support body. The filtration layer is composed of amorphous silica particles as a porous sintered body in a fine mode and has substantially the same purity as that of the support body.

Abstract: A device and method for permitting the separation of plasma or serum from whole blood. The device comprises a matrix of hydrophilic sintered porous material to which at least one red blood cell agglutinating agent has been applied. According to a first method of using the device, a sample of whole blood is applied to a first end of the matrix and the red blood cells within the sample come in contact with the agglutinating agents present in the matrix. The blood cells agglutinate, and are entrapped in the interstices of the matrix, while substantially blood-cell-free serum or plasma accumulates near the outlet of the device. A filter means in liquid receiving relationship with the matrix functions to wick the serum or plasma from the matrix.According to an alternative aspect of the invention, a filter means in liquid receiving relationship with the outlet of the matrix functions to retain any blood cells which pass through the matrix is the filter means wicks the plasma or serum from the matrix. Additional agglutinating agents may be incorporated within the filter means to facilitate retention of blood cells which pass through the matrix.
