The working principle of the new automatic potentiometric titrator
The automatic potentiometric titrator adopts the plunger titration method, and the single-chip microcomputer controls the plunger titration process to collect the dynamic signal of the electrode. use The CBS-1D automatic potentiometric titrator is suitable for volume analysis with potential as the detection index, and can be used as a special instrument for penicillin detection. Detection principle During the titration process, the solution in the titration cell produces different potential changes. When the potential change of △ E / △ V is greater than the threshold value, it is the equivalent point value. When the set conditions are met, the instrument goes to the stop procedure, stops the titration and gives Out the measurement result working principle The working principle of the automatic potentiometric titrator (hereinafter referred to as titrator) is to measure the ion concentration by measuring the change in electrode potential. First select the appropriate indicator electrode and reference electrode to form a working battery with the measured solution, then add the titrant. During the titration process, due to the chemical reaction, the concentration of the measured ions changes continuously, so the potential of the indicator electrode changes accordingly. Near the end of the titration, the concentration of the measured ions changes abruptly, causing a sudden jump in the electrode potential. Therefore, the end point of the titration can be determined according to the sudden jump in the electrode potential, and the measurement result is given. Instrument characteristics ⑴ Titration results are more accurate The signal collected during the titration is 0.1 mV, and the minimum titration feed can reach 0.0025 ml, which is about 10 times higher than the feed of other ordinary titrators. ⑵ Full Chinese display, easy operation and higher degree of automation The instrument is displayed in Chinese, the parameter setting is convenient and clear, the instrument automatically titrates, automatically alarms at the end point, and can print out the test report results. ⑶ With dynamic feed and quantitative feed The dynamic feed titration method automatically adjusts the feed amount as the potential changes. This method is more effective for the titration of penicillin degradation products. ⑷ Can distinguish multiple equivalence points The instrument has the same precise function as the similar foreign potentiometric titration instruments. It can be set to 1 ~ 9 equivalent points, with two stop modes: equivalent point stop and volume stop. The main function According to the type of titration chemical reaction: acid-base titration, redox titration, complex titration and precipitation titration. According to different points of titration solvent: aqueous solution titration and non-aqueous titration. According to different titration methods: chemical titration, penicillin content determination, penicillin calibration and penicillin degradation product measurement.
