<P>PROBLEM TO BE SOLVED: To improve detection sensitivity and detection accuracy as well as reproducibility in analysis based on light emission in plasma generated by electrical discharge in a sample solution. <P>SOLUTION: A flow channel 101 provided with a narrow part is filled with an electrically conductive sample solution. Plasma is generated in bubbles generated by applying an electric field in the flow channel. Regions in the flow channel other than the narrow part are regarded as regions of measurement interest to detect light emission. <P>COPYRIGHT: (C)2012,JPO&INPIT |
