Abstract: A blood purifier includes a porous molded body; exhibits an excellent blood compatibility wherein platelet adherence is inhibited and exhibits a good cytokine adsorption capacity and a low pressure loss before and after blood treatment; and can be safely used. A blood purifier includes a main vessel and a porous molded body housed in the main vessel. The porous molded body contains a hydrophobic polymer and a hydrophilic polymer. The amount of low-melting-point water per 1 g of dry weight of the porous molded body is 0.12 g to 2.00 g. The contact change ratio for the porous molded body is 0% to 0.2%. The ratio L/D is 1.00 to 2.30 where, for the region taken up by the porous molded body in the main vessel, L is the length in the flow direction and D is the circle-equivalent diameter of the cross section in the direction perpendicular to the flow direction.

Abstract: A system for solventless calibration of volatile or semi-volatile compounds and methods thereof. The system includes a fluid path having a first end configured to be operably coupled to a fluid source and a second end configured to be operably coupled to the analytical instrument. A solid sorbent is disposed along the fluid path and is configured to absorb an analyte. The flow of fluid along the fluid path from the first end to the second end causes absorbed analyte to be desorbed from the solid sorbent at a desired concentration to the instrument.

Abstract: The disclosure provides an agarose-cellulose nanocomposite porous gel microsphere, a preparation method, and an application. In the disclosure, agarose and nanocellulose are compounded to form a unique network structure by using an industrially scalable method, that is, a reversed-phase emulsification method. The maximum flow rate and pressure resistance of the porous gel microsphere are significantly improved. In addition, after the composite porous gel microsphere is modified with a specific ligand, the dynamic binding capacity of the separation target is improved, and the modified composite porous gel microsphere can be used for large-scale separation and purification of biological macromolecules. The disclosure adapts to the development trend of high rigidity, high flow rate, and high loading capacity of the chromatography medium, and is expected to be used as the next-generation chromatography medium with this performance.

Abstract: The present invention relates to a process for the manufacture of microporous carbon materials to perform selective separations of nitrogen in gas mixtures such as hydrogen sulfide, carbon dioxide, methane and C2, C3 and C4+ hydrocarbons, with high efficiency, shaped of microspheres or cylinders from copolymers of poly (vinylidene chloride-co-methyl acrylate) with density of 1.3 to 1.85 g/cm·sup·3 or poly (vinylidene chloride-co-vinyl chloride) with density of 1.3 to 1.85 g/cm.sup.3, using two stages. The first stage consists of a surface passivation of the material by chemical attack in a highly alkaline alcohol solution, with the aim of effecting a precarbonization on the surface of the copolymer that during the pyrolysis process is not deformed and gradually develops microporosity. The material of the first stage presents, in the layer, percentages between 55% to 85% carbon, between 5% to 20% oxygen, and between 10% to 40% chlorine. The interior of the material presents lower percentages of carbon, between 30% to 65%, oxygen in the amount of between 2% to 6%, and chlorine in the amount of between 30% to 60%. The second stage consists of the gradual pyrolysis of the passivated copolymer, with the aim of developing microporosity and high surface area values; as well as during the melting and gas dehydrohalogenation stages thereof, the deformation of the material is avoided. The morphology of the copolymers are microspheres of 125 to 225 micrometers, or cylinders of 4 mm in height and 3 mm in diameter, which after pyrolysis reduce its size by 35% with respect to the initial one. The material of the second stage, which is already microporous carbon material, presents in the layer percentages between 90% to 100% carbon and between 10% to 0% oxygen.
