The solution provides a method for separating a Chinese traditional medicine composition. To explain a pharmacological effect mechanism of a medicine made of two or more components and scientific content in rules of compatibility among components of a compound medicine, systematic researches on the material basis is very necessary. Accordingly, deep researches are done on chemical components of the pharmaceutical composition in the solution, and eight compounds are separated, which are 10-O-(p-hydroxycinnamoyl)-adoxosidic acid, aloe-emodin-8-O-β-D-glucopyranoside, quercitrin, matairesinol-4′-O-glucoside, liquiritin apioside, epi-vogeloside, vogeloside and ethyl caffeate, which provides a new quality control method for the composition in the solution.

Efficient methods for capture and removal of fibrinogen from blood plasma fractions, especially cryoprecipitate, and Fraction II+III providing high yields of blood coagulation Factor VIII are disclosed. According to this disclosure, there is provided a method of separating plasma cryoprecipitate or Fraction II+III comprising a blood coagulation factor and fibrinogen into a first fraction comprising the blood coagulation factor and a second fraction containing the fibrinogen, the method comprising: (a) contacting he plasma cryoprecipitate with solid SiO.sub.2 or Al(OH).sub.3, thereby adsorbing the fibrinogen onto the solid SiO.sub.2 or Al(OH).sub.3; and (b) separating the fibrinogen adsorbed onto the solid SiO.sub.2 or Al(OH).sub.3 from the blood factor, thereby forming the first fraction and the second fraction.

This invention relates to a method for the preparation of lithium carbonate from lithium chloride containing brines. The method can include a silica removal step, capturing lithium chloride, recovering lithium chloride, supplying lithium chloride to an electrochemical cell and producing lithium hydroxide, contacting the lithium hydroxide with carbon dioxide to produce lithium carbonate.

The present invention also discloses liquid chromatography columns for screening and identifying polymers that are substantive to a particular material, methods of preparing such liquid chromatography columns, and kits that may be used to screen and identify polymers that are substantive to a particular material.

A process for the preparation of a carrier-free Ga-68 solution from an irradiated Zn target, systems comprising components used in the process, and compositions comprising Ga-68 prepared by the process. Purification of Ga-68 is carried out by feeding an irradiation target solution comprising Zn-68, Ga-68 and solid target assembly metals into a system comprising three chromatography columns in succession.

A chromatography device (201; 201′) comprising: – at least one chromatography material unit (203), wherein said chromatography material unit comprises a convection-based chromatography material and is of a substantially rectangular shape having a length (L) and a width (W); - at least one fluid distribution system (207) which is configured to distribute fluid into and out from the at least one chromatography material unit (203), wherein said fluid distribution system (207) comprises a distribution device (209a) and a collection device (209b) between which said chromatography material unit (203) is sandwiched, wherein said distribution device (209a) and said collection device (209b) each comprises a number of parallel grooves (255) for distribution and collection respectively of a fluid to be passed through the chromatography material unit (203), wherein said parallel grooves are reaching over substantially the whole length (L) of the chromatography material unit (203) and are distributed over substantially the whole width (W) of the chromatography material unit (203).

Chromatography devices contain chromatography media and methods of making and methods of using chromatography devices. Chromatography devices enable a more efficient, productive and/or environmentally friendly chromatographic operation due to one or more of the following advantages over conventional chromatographic operations: elimination of a device packing step by the user; elimination of clean-in-place (CIP) steps; elimination of clean-in-place (CIP) steps utilizing sodium hydroxide solution; elimination of any validation steps by the user; and use of a chromatography device comprising biodegradable material. The chromatography media includes porous inorganic particles having a functionalized surface and having a median pore size of at least about 300 Angstroms (A), or at least about 300 A up to about 3000 A. The inorganic particles may have a BET surface area of at least about 20 m2/g, or at least about 25 m2/g, or about 30 m2/g, up to about 2000 m2/g.

The invention relates to a method of separation by fractionalization of the antioxidant active ingredients of Rosemary plant, which are the diterpenes Carnosic acid and Camosol and the phenolic acid Rosmarinic Acid, through column chromatography method. The production process involves the passage of rosemary extract, which is obtained in/with a proper solvent, through a column packed with a suitable packing material, the separation of the part rich in carnosic acid and carnosol, and the obtainment of a deodorized product in powder form after drying. During the process, another extract containing rosmarinic acid with high antioxidant activity is also obtained. The invention thus allows the use of an extract rich in carnosic acid and carnosol and another extract containing rosmarinic acid—which are obtained at once with no need for additional processes like acidification, precipitation, membrane filtration or deodorization—in food, pharmaceutical and cosmetic sector applications.
