Standalone Preheater for High Temperature Separations

The Caloratherm standalone preheater reaches an upper temperature limit of 100°C and can be easily integrated with any laboratory's HPLC equipment. The preheater, which operates in the isothermal mode, is for existing HPLC users who wish to experiment with temperature as a parameter to achieve better peak shapes and results in their chromatographic separations. The device, which is compatible with existing ovens, efficiently heats the mobile phase using a novel technique that eliminates band broadening and misshaped peaks. To overcome thermal mismatch, the preheater design consists of a low mass, low volume device, which can be positioned in the column inlet tubing to ensure responsive heat transfer into the mobile phase before it enters the column. Heating of the mobile phase is thereby performed completely independently from the oven but calibrated to the desired temperature to reach accurate thermal profiling.
