In one aspect, the present invention provides a chromatographic stationary phase material for various different modes of chromatography represented by Formula 1: [X](W).sub.a(Q).sub.b(T).sub.c (Formula 1). X can be a high purity chromatographic core composition having a surface comprising a silica core material, metal oxide core material, an inorganic-organic hybrid material or a group of block copolymers thereof. W can be absent and/or can include hydrogen and/or can include a hydroxyl on the surface of X. Q can be a functional group that minimizes retention variation over time (drift) under chromatographic conditions utilizing low water concentrations. T can include one or more hydrophilic, polar, ionizable, and/or charged functional groups that chromatographically interact with the analyte. Additionally, b and c can be positive numbers, with the ratio 0.05≤(b/c)≤100, and a≥0.

Methods and systems directed to the separation of tritium from an aqueous stream are described. The separation method is a multi-stage method that includes a first stage during which tritium of a tritium-contaminated aqueous stream is adsorbed onto a separation phase, a second stage during which the adsorbed tritium is exchanged with hydrogen in a gaseous stream to provide a gaseous stream with a high tritium concentration, and a third stage during which the tritium of the gaseous stream is separated from the gaseous stream as a gaseous tritium product.

The present invention relates to a method and production system for dealcoholization of beverages such as beers and wines.

Embodiments of the present disclosure describe functionalized polymeric membranes including one or more dithiol compounds that extend from a nanoparticle provided on or near a surface and/or pores of a polymer material, wherein at least one thiol of the dithiol compound binds to the nanoparticle and at least one thiol of the dithiol compound is a free thiol. Embodiments of the present disclosure further describe methods of separating and/or recovering a purified antibody comprising contacting a feed stream containing an antibody and other biomolecules with a functionalized polymeric membrane to separate the antibody from the feed stream; and applying a reducing agent to release the antibody from the membrane and recover a purified antibody; wherein the functionalized polymeric membrane includes a plurality of free thiols selective to binding the antibody.

A separation column for expanded bed adsorption comprises a column tube (2), a base (15) carrying an inlet rotor structure (6) for pumping in process liquid, and a top cap (3). The top cap (3) is conical in form, and has a peripheral flange 31 by which it is rigidly fixed to the top edge flange (22) of the column tube (2). The angle of the convergent interior surface (35) of the conical top cap (3) may be between 10 and 25°. A vortex-inhibitor component (8) projects down below the outlet structure (4) at the top of the cap, projecting into the operating space (15) of the column to inhibit rotation of liquid in the column interior. An expanded bed adsorption process is done with upward flow of liquid in the column through a bed of media particles.

The present invention relates to a type of aryl benzofuran amidated derivatives, the medical use thereof, and the preparation method; said derivatives have antioxidation activity, and xanthine oxidase inhibitory activity, and can be used for antioxidation and for preparing compositions, drugs and health products and treating gout and hyperuricemia.

The present invention provides a method for manufacturing antibodies or a fragment thereof with reduced levels of antibody reduction related impurities.

A method of fabricating an oleophilic foam includes providing a foam comprising a base material. The base material is coated with an inorganic material using at least one of an atomic layer deposition (ALD), a molecular layer deposition (MLD) or sequential infiltration synthesis (SIS) process. The SIS process includes at least one cycle of exposing the foam to a first metal precursor for a first predetermined time and a first partial pressure. The first metal precursor infiltrates at least a portion of the base material and binds with the base material. The foam is exposed to a second co-reactant precursor for a second predetermined time and a second partial pressure. The second co-reactant precursor reacts with the first metal precursor, thereby forming the inorganic material on the base material. The inorganic material infiltrating at least the portion of the base material. The inorganic material is functionalized with an oleophilic material.
