Chromatographic device for simultaneous collection and evaporation of sequential volatile non-aqueous eluates

摘要

The present disclosure relates to a chromatographic device for the simultaneous collection and evaporation of sequential volatile non- aqueous eluates. The device integrates collection and evaporation steps by continuously feeding the collected eluate directly to an evaporation vessel via a column delivery tube. As the solvent is evaporated from the evaporation vessel, eluate is continuously fed to said vessel, thereby eliminating the need for manual transfer and reducing the chances of contamination. The device increases the surface area available for evaporation, allows for the evaporation of volumes of solvent greater than the capacity of the evaporation vessel and allows for as much as a 5- fold reduction in the time necessary to carry out the chromatography and evaporation procedure.
