PURPOSE:To obtain a device which can make migration analysis under adequate migration conditions according to the detected condition of buffer solns. and has high analytical accuracy by providing means for detecting the development length of migration images and means for detecting the condition of the buffer solns. in migration vessels. CONSTITUTION:A conc. sensor, pH sensor and temp. sensor disposed in the migration box 1 are connected to a central control device 40 and the concn. pH value and temp. of each buffer soln. in each vessel of the box 1 made into two-vessel construction are inputted to the device 40. A colorimetric device 33 is connected to the device 40 and the development length of the fraction image of each specimen is inputted thereto. A memory 41 is connected to the device 40 and reference values, i.e., reference development length, reference buffer soln. concn., reference buffer soln. pH value and reference buffer soln. temp. as well as the relation between the change quantity thereof and the condition of the buffer solns. are preliminarily stored therein. The detected development length and reference development length are compared and the condition of the buffer soln. is confirmed in the device 40. The detected temp. and pH value of the buffer soln. 2 are considered and an instruction is given so as to make the adequate migration analysis in the box 1. |
