APPARATUS FOR CONDUCTING HIGH-TEMPERATURE LIQUID CHROMATOGRAPHY ANALYSIS

摘要

A system (Fig 8) for conducting high-temperature liquid chromatographic analysis includes a mobile phase transport tube (202) configured to operably convey mobile phase from a source to respective chromatographic instruments (206) in the system, a pre-heater (212) apparatus operably coupled to the mobile phase transport tube for heating the mobile phase to a desired temperature, a chromatographic column (206) operably coupled to the pre-heater apparatus, and including temperature-maintaining means (204) for maintaining the column at a pre-determined temperature and a counter-flow heat exchanger (212) operably exchanging heat from outlet mobile phase to inlet mobile phase trough conductive heat transfer means. In a particular embodiment, the mobile phase passing through the chromatographic column is maintained in a substantially adiabatic environment.
