Abstract
The present technology uses one or more separating segments, i.e. chromatography columns, aligned in series along a flow path. The separating segments are divided by a plurality of heating elements or are heated directly. The heating elements heat the supercritical mobile phase and sample to replace heat lost due to axial expansion of the mobile phase along the mobile phase flow path.
