The present invention pertains to apparatus and methods for measuring elastic modulus (Young's modulus) of non-solid materials, including honeycomb ceramic materials used in the filtration and/or treatment of exhaust gasses, through a range of temperatures.

Methods and apparatus for measuring elastic modulus of non-solid ceramic materials by resonance

An improved magnetic stirring apparatus capable of suspending solids in a liquid medium comprising: a vessel for containing fluids and solids, having walls, a bottom, and an opening; a stirrer having a magnetic impeller and a shaft, a means for rotating the magnetic impeller; and a closure; wherein the improvement is characterized by:

Magnetic stirring apparatus

Solid-phase immunoassay procedures employing magnetic glass or crystal-containing material, or a superparamagnetic material formed of magnetic particles dispersed in a non-magnetic matrix, as particulate carrier.

Solid-phase immunoassays using magnetic glass

Method of determining the concentration of a substance in a solution which comprises the steps of incubating the solution with a known amount of radioactively labelled substance and a suspendable composite consisting of anti-substance antibody coupled chemically through an intermediate silane coupling agent to an inorganic carrier, the incubation period being for a time sufficient to form immunochemical complexes, separating the complexes from the solution, determining the radioactivity of either the separated complexes or the remaining solution, and relating that determination to a standard curve. Specific assays for digoxin, insulin, and estriol are disclosed.
