Abstract: A filter includes a porous molding, the porous molding being a sintered product of mixed powder containing dry gel powder including an ion exchange resin and thermoplastic resin powder, or a swelled body of the sintered product. When water having an electric resistivity value of 18 MΩ·cm or more is allowed to pass through a space velocity of 1200 hr−1, the electric resistivity value of water after passage is 15 MΩ·cm or more.
To provide a filter that can efficiently remove metal ions in a solution to be treated, and easily acquire a solution having an extremely low content of metal ions.

Abstract: The invention relates to a method for obtaining an N-acetylglucosamine containing neutral oligosaccharide from a fermentation broth, wherein said oligosaccharide is produced by culturing a genetically modified microorganism capable of producing said oligosaccharide from an internalized carbohydrate precursor, comprising the steps of: i) ultrafiltration (UF), preferably to separate biomass from the broth, ii) nanofiltration (NF), preferably to concentrate said oligosaccharide in the broth and/or reduce an inorganic salt content of the broth, and iii) treating the broth with an ion exchange resin, preferably to remove charged materials, and/or subjecting the broth to chromatography, preferably to remove hydrophobic impurities.

Abstract: A method for the manufacture of highly purified 68Ge material for radiopharmaceutical purposes. The invention particularly concerns the production of 68Ge-API (API=Active Pharmaceutical Ingredient) solution complying with the Guidelines for good manufacturing practices (GMP). Starting material for the method of the present invention can be a 68Ge stock solution of commercial or other origin as raw material. Such 68Ge containing raw solutions are purified from potential metal and organic impurities originating from production processes. The radiochemical method disclosed is based on a twofold separation of 68Ge from organic and metallic impurities with two different adsorbent materials. During the first separation phase 68Ge is purified from both organic and metallic impurities by adsorption in germanium tetrachloride form, after which hydrolyzed 68Ge is purified from remaining metallic impurities by cation exchange. The final 68Ge-API-product e.g. fulfills the regulatory requirements for specifications of the GMP production of 68Ge/68Ga generators.

Abstract: A polysulfone membrane is modified so that monomers are grafted onto the surface of the membrane. The polysulfone membranes can be grafted by contacting the membrane with a grafting solution and exposing the membrane to electromagnetic radiation, typically within the ultraviolet portion of the spectrum. The monomers that are grafted are typically anionic or cationic. The grafted membranes can be used for filtering impurities, such as positively and negatively charged particles, from a liquid. Anionic membranes provide improved filtration of negatively charged impurities, while cationic membranes provide improved filtration of positively charged impurities.

Abstract: A polysulfone membrane is modified so that monomers are wafted onto the surface of the membrane. The polysulfone membranes can be grafted by contacting the membrane with a grafting solution and exposing the membrane to electromagnetic radiation, typically within the ultraviolet portion of the spectrum.
