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