An experimental setup for mobile chemical reaction interface is described. The unit is equipped with two constant current pumps for the continuous driving of catholyte and anolyte. Two electrodes connected to the logger are provided for measuring the voltage across the reaction tube. The device was tested with a mobile chemical reaction interface formed by 0.005 mol·L-1CoCl_2 and 0.01 mol·L-1 NaOH (containing 0.1 mol·L-1 background electrolyte KCl). The results show that: (1) the interference of hydrogen ions and hydroxyl ions generated during electrolysis can be well avoided; (2) multiple mobile chemical reaction interface experiments can be performed on a single gel column; (3) In the experiment or after the experiment can easily determine the length of the sedimentation zone; (4) can save a lot of catholyte and anolyte; (5) has good stability.
