Koj paub ntau npaum li cas txog pH sib xyaw electrodes?
Ib qho hluav taws xob uas sib txuas nrog pH iav electrode thiab siv hluav taws xob siv hu ua pH electrode. Yog hais tias lub plhaub yog ua los ntawm yas, nws yog hu ua lub plhaub yas pH composite electrode. Cov uas muaj lub plhaub iav yog hu ua iav pH sib xyaw electrodes. Qhov zoo tshaj plaws ntawm cov hluav taws xob sib xyaw yog tias lawv tau ua ke rau hauv ib qho thiab yooj yim siv. Cov qauv ntawm cov khoom siv hluav taws xob pH feem ntau yog cov khoom siv hluav taws xob, lub iav txhawb nqa pas nrig, ib qho kev siv hluav taws xob sab hauv, cov tshuaj siv sab hauv, lub plhaub, cov khoom siv hluav taws xob sab nraud, cov khoom siv sab nraud, cov kua hlws ris, lub hau electrode, electrode lead, lub qhov (socket), thiab lwm yam.
⑴ Electrode noob: Nws yog yaj-tshuab los ntawm lithium iav nrog hydrogen muaj nuj nqi. Nws yog spherical nyob rau hauv cov duab, nrog ib tug zaj duab xis thickness txog 0.1 ~ 0.2mm thiab ib tug kuj nqi ntawm<250 megaohms (25°C).
⑵Glass support tube: Nws yog lub iav raj uas txhawb nqa lub teeb hluav taws xob. Nws yog ua los ntawm cov hlau lead iav nrog zoo heev hluav taws xob rwb thaiv tsev. Nws expansion coefficient yuav tsum tau raws li cov electrode noob iav.
⑶ Internal reference electrode: Nws yog nyiaj chloride electrode. Nws lub luag haujlwm tseem ceeb yog kos tawm lub peev xwm electrode. Nws yuav tsum tau hais tias nws lub peev xwm ruaj khov thiab nws qhov kub coefficient yog me me.
⑷ Internal reference solution: Cov tshuaj siv sab hauv nrog xoom lub peev xwm ntawm 7pH yog cov tshuaj sib xyaw ntawm nruab nrab phosphate thiab potassium chloride. Cov iav electrode thiab cov ntaub ntawv siv hluav taws xob tsim lub roj teeb los tsim cov pH tus nqi ntawm xoom lub peev xwm, uas feem ntau yog nyob ntawm pH ntawm kev siv tshuaj sab hauv. tus nqi thiab chloride ion concentration.
⑸ Electrode yas plhaub: Lub plhaub yas electrode yog lub plhaub uas txhawb cov iav electrode thiab cov kua dej sib txuas thiab tuav cov kev siv sab nraud. Nws yog molded los ntawm PPS.
⑹ Sab nrauv siv electrode: Nws yog nyiaj / nyiaj chloride electrode. Nws txoj haujlwm yog los muab thiab tuav lub peev xwm siv tau ruaj khov. Nws yuav tsum tau muaj peev xwm ruaj khov, zoo reproducibility, thiab me me kub coefficient.
⑺ Kev siv sab nraud: 3.3 mol / L potassium chloride gel electrolyte, uas tsis yooj yim rau poob thiab tsis tas yuav ntxiv.
⑻ Sand core kua hlws ris: Cov kua dej sib txuas yog cov khoom sib txuas uas txuas cov kev siv sab nraud thiab cov kev ntsuas ntsuas, thiab yuav tsum muaj kev nkag mus ruaj khov.
⑼ Electrode hlau: Nws yog cov hlau tsis tshua muaj suab nrov shielded hlau. Cov tub ntxhais sab hauv yog txuas nrog cov khoom siv hluav taws xob sab hauv, thiab cov txheej txheem tiv thaiv yog txuas nrog rau sab nraud siv electrode.
