A method for preparing a crude oil solution for analysis, including adding water to a porous adsorbent to obtain a supported water substrate, having a plurality of water monolayers disposed on the porous adsorbent. The method further includes exposing the crude oil solution to the supported water substrate for a period of time; separating the supported water substrate from the crude oil solution; washing the supported water substrate with a water immiscible solvent to remove at least one hydrocarbon; displacing water from the plurality of water monolayers and the at least one interfacially active compound from the porous adsorbent with an alcohol and a co-solvent to obtain a displaced phase. The displaced phase can include the water, the at least one interfacially active compound, the alcohol, and the co-solvent. Finally, the method can include drying the displaced phase to isolate the at least one interfacially active compound.

The present invention describes a process for separating xylenes in simulated counter-current (simulated moving bed, SMB) for the treatment of feeds including oxygen-containing aromatic impurities of the phenol type and/or derivatives thereof, by controlled injection of water in the ingoing streams.

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

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.

An artificial, extracorporeal system for liver replacement and/or assistance, comprises a liver dialysis device for conducting hemodialysis on a patient suffering from liver failure. The liver dialysis device comprises a first standard hollow fiber membrane dialyzer which does not allow passage of an essential amount of albumin over the membrane wall and which is perfused with the patient's blood, and a second hollow fiber membrane dialyzer which allows the passage of essential but defined amounts of albumin over the membrane wall and which receives the blood of the first standard hemodialyzer. The filtrate space is closed off from the lumen space of the hollow fibers and is populated by adsorbent material which may comprise one or more different adsorbents.

The present invention is generally related to the analysis of chemical compositions of hydrocarbons and hydrocarbon blends. This method applies specifically to the problem of analyzing extremely complex hydrocarbon-containing mixtures when the number and diversity of molecules makes it impossible to realistically identify and quantify them individually in a reasonable timeframe and cost. The advantage to this method over prior art is the ability to separate and identify chemical constituents and solvent fractions based on their solvent-solubility characteristics, their high performance liquid chromatographic (HPLC) adsorption and desorption behaviors, and their interactions with stationary phases; and subsequently identify and quantify them at least partially using various combinations of non-destructive HPLC, destructive HPLC, and stand-alone detectors presently not routinely used for HPLC but reconfigured to obtain spectra on the fly. This analytical method is especially useful for, but not limited to, asphalt binders and asphalt binder blends, modified asphalts, asphalt modifiers, asphalt additives, polymer-modified asphalts, asphalts containing rejuvenators and softening agents, asphalts containing recycled products, aged asphalts, and air-blown asphalts, which may contain wide varieties of different types of additives and chemistries, and forensic applications, and environmental pollutant identification.
