Abstract: Regenerable gas purifier materials are provided capable of reducing the level of contaminants such as oxygen and water in an inert, nonreactive or reactive gas stream to parts-per-billion levels or sub-parts-per-billion levels. The purifier materials of this invention comprise a thin layer of one or more reduced forms of a metal oxide coated on the surface of a nonreactive substrate. The thin layer may further contain the completely reduced form of the metal.

Abstract: Trace impurities such as organic compounds and carbon monoxide are reduced to sub-ppb levels in gases such as nitrogen, helium and argon, by gas purifying systems that contain an ultra-low emission (ULE) carbon material. Ultra-low emission (ULE) carbon materials is capable of removing impurities from a gas stream down to parts-per-billion (ppb) and sub-ppb levels without concurrently emitting other impurities such as moisture or carbon dioxide to the purified gas stream. The carbon material is superactivated by heating the carbon to temperatures between 300-800° C. in an ultra-dry, inert gas stream. The ultra-low emission (ULE) carbon material is handled and stored in an environment that minimizes contamination from moisture and other oxygenated species in order to maintain its ppb and sub-ppb impurity removal and low emission properties.

Abstract: Trace impurities such as organic compounds in an inert, non-reactive or reactive liquid such as ammonia, hydrogen chloride, hydrogen bromide, and chlorine are reduced by at least a factor of 5 using liquid purifying systems that contain an ultra-low emission (ULE) carbon. The moisture level of the purified reactive liquid is only slightly higher than that of the contaminated liquid.

Abstract: The present invention provides a supported catalyst for in situ remediation of soil and/or groundwater contaminated with a halogenated hydrocarbon comprising an adsorbent impregnated with zero valent iron, wherein the adsorbent is capable of adsorbing the halogenated hydrocarbon. This invention further provides a bioremediation composition for in situ bioremediation of soil and/or groundwater contaminated with hydrocarbons, comprising an adsorbent capable of adsorbing said hydrocarbons, a mixture of facultative anaerobes capable of metabolizing said hydrocarbons under sulfate-reduction conditions, a sulfate-containing compound that releases sulfate over a period of time, and a nutrient system for promoting growth of said anaerobes, wherein said nutrient system includes a sulfide scavenging agent.

Abstract: Gas purifier system containing a preconditioned ultra-low emission (P-ULE) carbon for reducing trace impurities such as organic compounds and carbon monoxide in reactive fluids such as ammonia, hydrogen chloride, hydrogen bromide, and chlorine to sub-ppb levels. P-ULE is capable of removing impurities from a reactive fluid down to parts-per-billion (ppb) and sub-ppb levels without concurrently emitting other impurities such as moisture or carbon dioxide into the purified reactive fluid. The P-ULE carbon is prepared by heating a carbon material to temperatures between about 300° C. to 800° C. in an ultra-dry, inert gas stream, to produce an ultra-low emission (ULE) carbon material, subjecting the ULE carbon to a second activation process under a reactive gas atmosphere to produce a P-ULE carbon and storing the P-ULE carbon in an environment that minimizes contamination of the P-ULE prior to its use in a gas purifier system.

Abstract: This invention includes both a one-column process and a two-column process for the preparation of compositions enriched for anthocyanins from a crude plant extract. Both processes include a novel column purification step using a brominated polystyrene resin. This invention also includes extracts enriched for anthocyanins.

Abstract: An apparatus is provided for performing an activated clotting time test on a sample of blood containing platelets, the apparatus comprising a plurality of test cells, said cells being adapted for receiving an aliquot portion of said sample, wherein each of said cells comprises an anticoagulant and a platelet inactivating agent, and wherein at least one of said cells further comprises a clotting activator, wherein a clotting time is determined for each of said aliquot portions, and wherein a relative clotting time for each of said aliquot portions comprising the clotting activator is determined as compared to a reference clotting time for said at least one cell containing no clotting activator, wherein said relative clotting times in said cells are determinative of the clotting activation of said clotting activator.
