    Abstract: PROBLEM TO BE SOLVED: To accurately position a sample introduced to a reaction flow path. SOLUTION: The sample 3 is continuously introduced together with an oil component from a sample inlet 6 in a reaction flow path 4 so as to give a multiphase liquid of liquid phase 5a-sample 3-oil phase 5b. A light measurement part 14 is equipped with a light source part for emitting a light and a light detector for detecting a light, the reaction flow path 4 is irradiated with a light from the light measurement part through a window 17, a reflected light, transmitted light or scattered light at the time of the operation is measured by the light detector to detect an optical change inside the reaction flow path 4. When the multiphase liquid composed of the oil phases and the sample is moved so as to be passed through a photoirradiation position from the light source part of the light measurement part 14, a change in optical characteristics at an interface between the oil phases and the sample occurs due to difference in optical characteristics between the oil phases and the sample, the optical change is detected so that the positions of the interfaces between the oil phases and the sample can be detected and the position of the sample 3 can be detected.
