Lub ntsuas ntshav qabzib, tseem hu ua ntshav ntsuas ntshav, yog cov cuab yeej hluav taws xob siv los ntsuas cov ntshav qabzib. Cov ntshav ntsuas ntshav tau muab faib ua ob hom raws li lawv txoj haujlwm ua haujlwm: photoelectric thiab electrode-raws li. Electrode-raws li cov ntshav qabzib ntsuas muaj cov qauv ntsuas kev tshawb fawb ntau dua, thiab cov electrodes tuaj yeem ua ke nrog hauv.
Kev ntsuas ntshav qabzib feem ntau siv peb -electrode system los ntawm electrochemical tsom xam. Peb -electrode system, uas tsis yog ib txwm siv ob-electrode system, suav nrog cov khoom siv hluav taws xob ua haujlwm (WE), cov khoom siv hluav taws xob (RE), thiab lub txee electrode (CE). Cov ntaub ntawv siv electrode yog siv los txiav txim qhov zero point. Tam sim no ntws los ntawm kev ua hauj lwm electrode thiab cov ntaub ntawv siv electrode, tsim ib qho system nrog me me los yog tsis muaj tam sim no ntws. Kev ruaj ntseg ntawm cov khoom siv hluav taws xob siv hluav taws xob yog siv los ntsuas lub peev xwm electrode ntawm kev ua haujlwm electrode.
Cov electrode ua hauj lwm thiab cov auxiliary electrode tsim ib qho tam sim no -flowing system, siv los ntsuas qhov tam sim no ntws los ntawm kev ua hauj lwm electrode. Qhov peb -electrode ntsuas qhov system tso cai rau kev kawm ib txhij ntawm kev sib raug zoo ntawm lub peev xwm thiab tam sim no ntawm cov electrode ua haujlwm.
