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.

La présente invention concerne un système (Fig. 8) utilisé pour l'analyse chromatographique en phase liquide à haute température. Il comporte un tube de transport de phase mobile (202) chargé de transporter, de par sa configuration, la phase mobile depuis une source jusqu'aux différents instruments de chromatographie (206) du système. Le système comporte également un réchauffeur (212) qui de par son couplage au tube de transport de phase mobile, servant à amener à la phase mobile la température voulue. La colonne de chromatographie (206), qui est fonctionnellement couplée au réchauffeur, est équipée d'un dispositif thermostatique (204) assurant le maintien de la colonne à une température définie. En outre, un échangeur thermique monté à contre-courant (212) est chargé de l'échange de chaleur de la phase mobile sortante vers la phase mobile entrante via des structures de transfert thermoconductrices. Selon un mode de réalisation particulier, la phase mobile transitant par la colonne de chromatographie est maintenue sensiblement en adiabatisme.
