摘要:
A method of, and an apparatus for, conducting chromatographic separations of multi-component systems utilizing silica-coated, magnetically susceptible particles in an MSFB is disclosed. A support material comprised of beads having a magnetic core surrounded by a silica derivative porous coating is used.
摘要:
Disclosed is a method of conducting affinity chromatographic separations of biomaterials which comprises contacting the biomaterial with a solid support comprising a generally spherical bead having a generally central magnetic core and a surrounding exterior coat about the core comprising a material capable of binding with the biomaterial.

摘要:
A method and system for analyzing gas concentration by measuring the steady state pressure in a dual membrane cell. A first membrane is exposed to a test gas and a second membrane to a reference gas where the first and second membranes have differing permeabilities. The test gas and the reference gas continuously counterdiffuse through the membranes and the steady state pressure in the intermembrane space is directly proportional to the gas concentration of the test gas component.
