A zearalenone functionalized graphene surface molecularly imprinted material, a preparation method therefor and the use thereof, which belong to the technical field of molecularly imprinted materials. The zearalenone functionalized graphene surface molecularly imprinted material is prepared by using RGO as a carrier, CDHB as a template molecule, 1-ALPP as a functional monomer, TRIM as a cross-linking agent, AIBN as an initiator, and acetonitrile as a pore-forming agent.

The present disclosure provides chromatography columns and methods of chromatographic separation using the same. In particular, the disclosure provides modified columns where the cross-sectional area of the column increases in an area near the end of the column in a flared manner. The modified columns can be used in Expanded Bed Absorption (EBA) systems.

A valve block includes a fluid-transfer plate with multiple inlet bores connecting to a common inlet channel, and multiple outlet bores connecting to a common outlet channel. The inlet bores and the outlet bores are arranged in a curved shape. The valve block also includes a pressure plate and diaphragm aligned and connected to the fluid-transfer plate in a way that allows pressurized material in the pressure plate to control the state of the channels formed by the inlet and outlet bores.

The invention provides metal liquid chromatography components with uniformly coated internal surfaces and methods for achieving the same. The invention addresses the problem of corrosion or interference of metal components in the flow path for LC analyses in which the sample interacts with metal ions or surfaces. The invention also alleviates the difficulties in coating very long metal tubes and very small metal channels with an inert, continuous coating that adheres well to metal surfaces. The metal flow path is rendered inert by the coating, and thus compatible with bioanalytical separations, for example, by using a vapor phase deposition process to coat the inner surfaces with a coating that continuously covers all metal surfaces in the flow path.
