This study demonstrates a photothermal image analysis for the capillary electrophoresis (CE). The Photothermal image analysis is a new detection method that combines the photothermal effect with the image analysis technique. The heat caused by the absorption of an excitation beam from the sample leads to the change in the aspect of a probe beam periodically. Since the probe beam is used as a reference indicating the signal of the photothermal effect due to the absorption of excitation energy at the sample, the detection of the signal is performed by observing the size or position changes of the probe beam. These changes are continuously monitored and analyzed in real time using a camera system and the signal amplitude is determined through FFT. It is possible to detect the changes of the probe beam by the heat generated from the sample flow in a capillary. A mixture of few different dye samples is separated in time by the CE and then detected by the photothermal image analysis. This new detection method is found to possess its advantage of wide applicability in various conditions with a high sensitivity.
