摘要:
Devices and associated processes suitable for small and large scale purification of molecules in a fluid, and provides embodiments that overcome the difficulties of transitioning purification from research stages to production scale-up. The invention relates to the formation and characteristics of substantially uniform, continuous, and homogeneous porous separation matrices. The matrices are in the form of a polymeric layer with substantially uniform thickness and porosity. The polymeric layer is formed for the purpose of providing convective flow through the separation matrix.

An object of the present invention is to provide a method capable of measuring stable hemoglobin A1c using liquid chromatography in a short time with good reproducibility. The present invention is a method for measuring stable hemoglobin A1c using liquid chromatography, installing on a flow path of a liquid chromatograph a filter whose surface is treated with a solution containing 1 to 50% by weight of a silicone oil or a solution containing 1 to 50% by weight of a silicone resin,; and setting a pressure value generated in a measurement system of the liquid chromatograph to 9.8 × 10 3 Pa or more and 19.6 × 10 5 Pa or less.

The invention relates to miniaturized separating columns whose separating means are formed from an individual porous hollow fibrous membrane which has undergone a derivatization with separation effectors. In addition, the separating columns are provided with connections for admitting and discharging eluting agents.
摘要:
A column for concentrating a component in a sample is used for high performance liquid chromatography and comprises a membrane for diffusing an object component and a membrane for absorbing an object component. The column is useful especially for microcolumn liquid chromatography.
摘要:
The invention relates to an apparatus useful for the separation of at least one preselected ligate present in a fluid. The invention also features an easily scaled-up membrane affinity separation process which is highly reliable, highly selective, provides a high yield of product, and is further characterized by a high volumetric throughput. The invention utilizes a substantially isotropic porous membrane, to which is associated a preselected ligand, which provides an optimum loading capacity and low dead volume while allowing high filtrate flow rates. Methods for isolating macromolecules having therapeutic value are described.
摘要:
A device for capturing a component present in a fluid comprises a pipette tip having a rearward end 15 adapted to be fitted on a micro-pipette, and a forward end 12 with a membrane 17, adapted to bind the component, extending across the pipette tip.
