An apparatus for reaction chromatography comprising: a chromatography column, the column having a fluid outlet for an eluate flow, wherein the fluid outlet is configured with two or more fluid ports, the two or more fluid ports comprising one or more reactant ports, wherein each reactant port is for connecting a reactant flow into the eluate flow to react with the eluate flow, and one or more product ports for receiving the reacted eluate flow; one or more reactant sources in fluid communication with the one or more reactant ports to provide the reactant flow; and one or more processing units in fluid communication with the one or more product ports to process the reacted eluate flow.

Method and apparatus for reaction chromatography

An apparatus and a method are provided for column chromatography which provide improvements in separation resolution and detection sensitivity, comprising a chromatography column, the column having an inlet and an outlet, wherein the outlet is configured to split a flow of eluate as it leaves the column through the outlet into at least two separate portions, wherein the apparatus is configured to separately process the portions, for example to separately detect a portion or separately collect fractions of a portion with improved resolution. A split frit assembly is preferably configured to split the flow of eluate. The portions preferably emanate from different radial regions of the column. An end fitting for the column outlet may be provided having multiple ports to separately convey the portions.

Method and apparatus for improved resolution chromatography

An apparatus and a method are provided for column chromatography, which provide improvements in separation resolution and detection sensitivity, comprising a chromatography column having an inlet and an outlet, wherein the inlet is configured to introduce a flow of mobile phase into the column carrying a sample, wherein the inlet is further configured to introduce the flow of mobile phase into the column in at least two separate portions which are independently controllable, and to introduce the portions into different radial regions of the column, such that the portions flow longitudinally through the column in different radial regions. The sample preferably is contained in one of the portions, especially a central portion, in a higher concentration than in the other portion(s). Preferably the flow velocities of the portions are independently controllable.
