Abstract
Described are an interface module for two-dimensional chromatography and a method of performing a chromatographic separation that may use the interface module. The interface module includes a valve module, a collection needle, a modifier module and a sample storage element. The valve module has a first port configured to receive an eluent from a first chromatography system, a second port configured to provide a fraction obtained from the eluent, a third port and a fourth port. The collection needle and the modifier module are in fluidic communication with the valve module at the third and fourth ports, respectively. The modifier module includes a source of a modifier solvent. The sample storage element is in fluidic communication with the valve module and is configured to receive a volume of the fraction for injection as a sample into a second chromatography system.
