A CHROMATOGRAPHY DEVICE

A chromatography device (1; 101) comprising: —at least one chromatography material unit (3), wherein said chromatography material unit comprises a convection-based chromatography material; —at least one fluid distribution system (7) which is configured to distribute fluid into and out from the at least one chromatography material unit (3); —an inlet (15); —at least one inlet fluid channel (17a, 17b) connecting the inlet (15) with each chromatography material unit (3) via the fluid distribution system (7); —an outlet (19); and —at least one outlet fluid channel (21) connecting the outlet (19) with each chromatography material unit (3) via the fluid distribution system (7), wherein at least some parts of said chromatography device (1; 101) are overmolded and sealed together by plastic or elastomer leaving at least the inlet (15) and the outlet (19) open.

Method for separating eighteen components in traditional Chinese medicine composition

The disclosure provides a method for separating eighteen components in a traditional Chinese medicine composition, including: (1) preparing the traditional Chinese medicine composition into a total extract of the traditional Chinese medicine composition, separating by resin through sequentially eluting with water, 10% ethanol and 30% ethanol, and collecting the 30% ethanol eluate to obtain a 30% ethanol extract; (2) adding the 30% ethanol extract to a reverse phase silica gel ODS-AQ-HG, and separating in a medium pressure separation column to obtain differently numbered elution dry pastes; (3) dissolving the differently numbered elution dry paste with 30% methanol as a solvent, and passing the solution through a 0.45 μm microporous membrane, carrying out a primary separation by high performance liquid chromatography and collecting chromatographic peaks with different retention times, and further purifying by high performance liquid chromatography; finally obtaining the components of eighteen components.

LIQUID PHASE SEPARATION OF 2G SUGARS BY ADSORPTION ON A FAU ZEOLITE HAVING A SI/AL ATOMIC RATIO GREATER THAN 1.5

The invention relates to a process for the liquid-phase separation of glucose from a mixture of C5 and C6 sugars comprising at least xylose and glucose, by adsorption of glucose on a zeolitic adsorbent based on FAU-type zeolite crystals having an Si/Al atomic ratio strictly greater than 1.5 comprising barium, wherein: said mixture is brought into contact with said adsorbent, by liquid chromatography, to obtain a xylose-enriched liquid phase and a glucose-enriched adsorbed phase; on the one hand, said xylose-enriched liquid phase is recovered and said phase adsorbed on said adsorbent is desorbed by means of a desorption solvent in order to recover the glucose on the other hand.

Reduced leaching of a ligand
11458236 · 2022-10-04 · ·

A column for removal of a component from a fluid is disclosed. The column has a compartment with a cross sectional area. The compartment contains beads having a diameter. A ligand selected to bind to the component is coupled to the beads. The cross-sectional area and bead diameter are selected to maintain a flow velocity of the fluid within the compartment below a first threshold, thereby reducing leaching of the ligand into the fluid. Also described herein is an adsorbent comprising a ligand that is attached to a substrate by an amine bond, wherein the ligand is resistant to dissociation from the substrate.
