I need a procedure for measuring isoelectric point of polymer by potentiometric titration method.
thanks
Dear Esmaeil Hasani, you may find various procedures with respect to the polyampholyte in question. Other thing to mention is that 'capillary isoelectric focusing (CIEF)' is widely used for such a purpose. Please check the attached files. My Regards
