Abstract: The present disclosure relates to a method performed in an interface system, the interface system comprising a reactor and a reaction-product-separator, the method comprising: (a) guiding a liquid containing analytes to and through the reactor and causing a component comprised by the analytes to react to a reaction product in the reactor, to thus create a post-reactor liquid comprising the reaction product, (b) guiding the post-reactor liquid from the reactor to the reaction-product-separator and through the reaction-product-separator, and separating the reaction product from the post-reactor liquid, to thus create a post-separator fluid, and (c) guiding at least one rinsing liquid through at least one of the reactor and the reaction-product-separator. The present invention also relates to an interface system, wherein the system is configured to perform the method, wherein the interface system comprises the reactor and the reaction-product-separator.

Abstract: A reactor for a liquid chromatography system comprises a first capillary cartridge, a second capillary cartridge, a first housing for accommodating the first capillary cartridge, and a second housing for accommodating the second capillary cartridge. The first housing comprises a heating element for heating the first capillary cartridge. The second housing can comprise a cooling element for cooling the second capillary cartridge.

Abstract: An interface for coupling a liquid chromatography device to a mass spectrometry device comprises a reactor for chemically converting analytes eluting from the liquid chromatography device and a housing for accommodating the reactor. The reactor is arranged on a tray in the housing, which tray is slidable in a substantially horizontal plane relative to the housing so as to facilitate access to the reactor.
