The present invention relates to a method for effectively utilizing fructose raffinate obtained in the process for separating psicose conversion product with a high purity chromatography in the process for preparing psicose, and more specifically, it is utilized for preparation of fructose-containing raw material solution for preparing psicose by supplying the fructose raffinate obtained in the separation step of psicose preparation into the psicose conversion reaction.

The present disclosure relates to methods of modifying complex extracts such that components or mixtures of components are selectively removed or added, thus providing a complex mixture that does not naturally occur with a refined or a tuned therapeutic or nutraceutical effect. In various aspects, the complex extract can be an extract obtained from one or more plants, e.g., an extract obtained from green tea leaves. The present disclosure pertains to compositions obtained by the disclosed methods, nutraceutical compositions comprising same, pharmaceutical compositions comprising same, and methods of treating various conditions, including physiological dysfunctions associated with elevated reactive oxygen species and/or inflammatory molecule, e.g., TNFα, expression using same. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

In a method for processing successive fluidic sample portions provided by a sample source, sample reception volumes are filled successively temporarily with at least a respective one of the sample sections, and the sample sections are emptied successively out of the sample reception volumes in such a way, that, while emptying, it is avoided to bring two respective ones of the sample sections, which have not left the sample source directly adjacent to one another, in contact with one another.

A chromatography system for separation of a biopolymer is described, comprising at least one feed tank, at least one hold tank, at least one elution buffer tank, at least one eluate tank, at least two packed bed chromatography columns and at least one pump and at least one outlet detector both fluidically connected to said each packed bed chromatography column, wherein the feed tank, the hold tank(s), the elution buffer tank and the eluate tank are each fluidically connected to the packed bed chromatography columns via a system of valves.

A water purification apparatus includes a bottomed cylindrical container tank, a lid member for fluid-tightly closing an upper opening of the container tank, an upper filter which forms an upper space between the lid member and itself, a lower filter which forms a lower space between a bottom plate of the container tank and itself, a water passage pipe which passes through the upper and lower filters and which establishes a communication between the upper and lower spaces, and an ion-exchange resin loaded in a space defined by the container tank, the upper and lower filters and the water passage pipe. The lid member has a water supply pipe for supplying water to the upper space, and an overflow pipe which connects to the water passage pipe. A water conveyance pipe for discharging the pure water in the container tank to outside is connected to the lower space.

There is provided a system for separation of analytes in a solution. The system encompasses a disposable cartridge enclosing a sorbent for binding the analytes in a solution and a conduit establishing a fluid link to a valve having a holding-loop to achieve elution through the cartridge at low pressures. The valve is switchable to a position following the elution from the cartridge for emptying through an outlet port at high pressures such as those required for moving liquid through chromatographic columns.
