電化學工作站分類

電化學工(gong)作站可根據其(qi)通(tong)道個數(shu)(shu)的不同分為(wei)單通(tong)道和(he)多通(tong)道兩種，其(qi)中(zhong)，單通(tong)道工(gong)作站在一定時(shi)間內只允(yun)許(xu)完成對(dui)一個樣品(pin)的參數(shu)(shu)測量，而(er)多通(tong)道工(gong)作站允(yun)許(xu)同時(shi)對(dui)多個樣品(pin)進(jin)行參數(shu)(shu)測量，大大提供了(le)其(qi)工(gong)作效率。

電化學工作站原理

電(dian)(dian)(dian)(dian)化學工(gong)(gong)(gong)作(zuo)(zuo)(zuo)站具有工(gong)(gong)(gong)作(zuo)(zuo)(zuo)電(dian)(dian)(dian)(dian)極(ji)(ji)、輔助電(dian)(dian)(dian)(dian)極(ji)(ji)、參比電(dian)(dian)(dian)(dian)極(ji)(ji)三個電(dian)(dian)(dian)(dian)極(ji)(ji)，其中(zhong)(zhong)，工(gong)(gong)(gong)作(zuo)(zuo)(zuo)電(dian)(dian)(dian)(dian)極(ji)(ji)需(xu)要(yao)被測量(liang)的(de)未知電(dian)(dian)(dian)(dian)極(ji)(ji)；輔助電(dian)(dian)(dian)(dian)極(ji)(ji)在(zai)對工(gong)(gong)(gong)作(zuo)(zuo)(zuo)電(dian)(dian)(dian)(dian)極(ji)(ji)的(de)測量(liang)過(guo)程(cheng)中(zhong)(zhong)起(qi)到(dao)輔助作(zuo)(zuo)(zuo)用，主要(yao)用于與工(gong)(gong)(gong)作(zuo)(zuo)(zuo)電(dian)(dian)(dian)(dian)極(ji)(ji)一起(qi)形(xing)成閉(bi)合回路(lu)；參比電(dian)(dian)(dian)(dian)極(ji)(ji)在(zai)對工(gong)(gong)(gong)作(zuo)(zuo)(zuo)電(dian)(dian)(dian)(dian)極(ji)(ji)的(de)測量(liang)過(guo)程(cheng)中(zhong)(zhong)起(qi)到(dao)參考的(de)作(zuo)(zuo)(zuo)用，其電(dian)(dian)(dian)(dian)勢是固(gu)定(ding)且已知的(de)，因此可通過(guo)對工(gong)(gong)(gong)作(zuo)(zuo)(zuo)電(dian)(dian)(dian)(dian)極(ji)(ji)與參比電(dian)(dian)(dian)(dian)極(ji)(ji)之間的(de)電(dian)(dian)(dian)(dian)勢差的(de)求解(jie)來得到(dao)工(gong)(gong)(gong)作(zuo)(zuo)(zuo)電(dian)(dian)(dian)(dian)極(ji)(ji)的(de)電(dian)(dian)(dian)(dian)勢。
