The present invention relates to a polymer molecular weight measuring device and a measuring method. The polymer molecular weight measuring device is located in the reaction unit, the reaction unit containing the reaction solution containing the redox species and the polymer sample, the electrode unit including the counter electrode, the reference electrode and the working electrode, and the surface of the working electrode of the electrode unit to include a measuring unit for measuring the intensity of current generated when the redox species collide or adsorb. According to the present invention, even with a small amount of polymer sample, it is possible to quickly and accurately measure the molecular weight and the degree of synthesis of the polymer through the electrochemical method. |
