PROBLEM TO BE SOLVED: To efficiently determine and mix a sample solution and a reagent solution. SOLUTION: An analyzer comprises a first segment inlet and liquid feed section 1, having a first injector 9a and a first pump 7a for introducing a first segment; a second segment inlet and liquid feed section 3, having a second injector 9b and a second pump 7b; a microchip 11 having a Y-shaped microchannel consisting of a first channel 13a, a second channel 13b, and a detection channel 15; and a detector 19. Laminar flow is formed in the detection channel 15; the first segment with a predetermined amount that is introduced by the first injector 9a and the second segment with a predetermined amount that is introduced by the second injector 9b are converged at a junction 17; the first segment and the second segment are diffused in the detection channel 15, in a direction perpendicular to the interface between the first segment and the second segment, and the first segment and the second segment are mixed instantaneously and react.
