摘要： The present invention is for solving a problem, and the purpose of the present invention is to provide an analysis system capable of using an expensive commercial DNPH cartridge, replacing an HPLC that is complicated to operate, and separating and detecting aldehydes or ketones in a more economical and simpler manner. A rotary analysis system of the present invention comprises: a rotary unit including a rotary platform, and having a TLC plate on which the rotary motion of the rotary platform causes the movement of a fluid sample and an eluent to be controlled on the rotary platform and on which the aldehydes or ketones of the sample are separately developed with the eluent; a photographing unit for photographing the components of the sample separated by the rotary unit; a control unit for controlling the rotation conditions of the rotary unit and the photographing conditions of the photographing unit; and an analysis unit for analyzing an image captured by the photographing unit.
