On-line coupling between capillary electrophoresis and microscale thermophoresis (CE-MST); the proof-of-concept.

We demonstrate that microscale thermophoresis can be easily coupled with capillary electrophoresis in an on-line flow system (CE-MST), offering new potential possibilities. It takes advantage of sample separation and miniaturization prior to thermo-optical/MST analysis. No instrument modification is required. The future perspective is discussed.
