Abstract: The present disclosure relates to a system and regenerable molecular media for wastewater purification treatment and a preparation method thereof. The molecular filter media of the present invention are extremely high surface area filter granules and pellets that are either supplied loose or molded into blocks. The industry uses these for filtration in flow-through filter devices. The disclosed regenerants effectively break bonds and get the molecular filters ready for the next cycle of use.

Abstract: An apparatus is for the automated production of a daughter radionuclide from a parent radionuclide using a generator comprising a solid medium onto which the parent nuclide is fixed and whereby the daughter nuclide is formed by radioactive decay of the parent nuclide. The apparatus includes a fluid circuit including a chromatography column having a head port and a tail port, at least one connection port for connecting the generator to the fluid circuit, at least one inlet port for connecting fluid sources to the fluid circuit and at least one valve controlled by an electronic control unit for selectively connecting the chromatography column, the connection port and the at least one inlet port in various configurations. The various configurations include a first elution configuration for circulating an A1′ solution exiting the generator and containing the daughter radionuclide, through the chromatography column from the head port to the tail port for loading the chromatography column with the daughter radionuclide; a first washing configuration for circulating an A2 washing solution from a solution inlet through the chromatography column from the head port to the tail port; and a second washing configuration for circulating an A2′ washing solution from a solution inlet through the chromatography column from the tail port to the head port.

Abstract: A method for packing a chromatography column with chromatography media, comprising the steps of: providing a system comprising a column tube having a closed first end comprising an inlet/outlet, a media inlet adjacent a second end of the column tube and an adaptor positioned inside the column tube initially adjacent the second end of the column tube for sliding and sealing contact with an inner face of the column tube, the column tube and adaptor arranged initially such that they define an internal volume and such that the media inlet is in fluid connection with the internal volume; connecting a media slurry source to the media inlet; at least partially filling the internal volume with media slurry via the media inlet; forcing the adaptor towards the first end of the column tube to reduce the internal volume such that the media inlet is no longer in fluid connection with the reduced internal volume.

Abstract: A chromatography system has a cartridge adapter that is detachably attachable to enable a chromatography cartridge to be quickly interchanged. Chromatography cartridges are configured with threads for coupling to a corresponding interchangeable coupling component having matching threads. The interchangeable coupling component may be secured to the chromatography system by a coupling retainer. A coupling retainer may have a keyway that is configured for quick interchanging of the interchangeable coupling components. The interchangeable coupling component may have a pair of parallel sides that align with a slot of the keyway to secure the interchangeable coupling components to the coupling retainer. An inlet nipple of the chromatography cartridge may extend through an opening in the coupling components and couple to an inlet conduit for sample gas. Analyte gas may flow back to the chromatography system for detection and collection.

Abstract: A composition and method for the removal of water from a water-containing hydrocarbon stream, and a method for the production of a metal/water-soluble polymer composite are provided. The composite includes a water-soluble polymer, such as guar gum, and a metal salt, such as aluminum nitrate or copper sulfate. The ratio of the metal salt to the water-soluble polymer is in the range from about 1:1 to about 5:1 by mass. The water-soluble polymer and the metal salt form a crosslinked material. The method for producing the metal/water-soluble polymer composite includes mixing a non-crosslinked water-soluble polymer with a metal salt and water to form a paste. The paste is then dried.

Abstract: Disclosed is a method for identifying the accurate number of peaks which includes a peak extraction process of extracting a number of target peaks corresponding to a number of target components to be identified, among the multiple components from a group of peaks appearing on the chromatogram, a peak identification process that assigns names of the target components to the target peaks in descending or ascending order of first retention time, based on a standard sample timetable preloaded with a relationship between the names of the target components and the corresponding first retention times, which are retention times of the target components, is stored, and a standard sample timetable updating process that updates the first retention times in the standard sample timetable, with second retention times that are measured retention times of the target peaks.

Abstract: A method for producing a chromatography carrier, including providing a solid phase support, where the solid phase support provided is formed of porous particles on which a ligand has or has not been immobilized, and subjecting the solid phase support to sieve classification. A coefficient of variation of a volume particle size distribution of the porous particles when a ligand has been immobilized is adjusted to 1% to 22%, and a ratio (d1/d50) of volume cumulative 1% particle size d1 to volume cumulative 50% particle size d50 in terms of the porous particles is adjusted to 0.55 to 1.0.
