pH Electrode Cov lus nug nquag nug
1. Lub neej ua haujlwm ntawm pH electrode yog dab tsi?
Lub neej ntawm kev siv thiab tswj pH electrode yuav tsum yog li ntawm ib mus rau peb xyoos. Cov yam ntxwv uas tuaj yeem ua rau lub neej luv luv ntawm cov electrode muaj xws li qhov kub thiab txias thiab ntsuas ntawm huab cua pH, uas tuaj yeem ua rau lub neej luv luv txawm tias muaj cov khoom siv hluav taws xob zoo thiab khaws cia. Yog tias qhov ua tau zoo ntawm electrode pib deteriorate, pH rhiab iav daim nyias nyias tuaj yeem rov tsim dua tshiab thiab cov khoom siv hluav taws xob tuaj yeem rov qab mus rau nws qib qub.
2. Kuv yuav xaiv txoj cai pH electrode li cas?
Txhawm rau kom ntseeg tau tias qhov ntsuas pH zoo tshaj plaws, nws yog ib qho tseem ceeb uas yuav tsum xaiv cov pH electrode kom raug rau txhua daim ntawv thov. Cov qauv tseem ceeb tshaj plaws yog: tshuaj muaj pes tsawg leeg, homogeneity, kub, txheej txheem siab, pH ntau thiab cov hlab ntsha loj (ntev thiab dav txwv). Kev xaiv ntawm electrode yog ib qho tseem ceeb tshwj xeeb rau cov tsis muaj dej, tsis tshua muaj hluav taws xob, muaj protein ntau thiab viscous ntsuas xov xwm, qhov twg cov iav electrodes feem ntau cuam tshuam rau ntau qhov kev cuam tshuam sib txawv uas tuaj yeem ua rau kev ntsuas yuam kev. Lub sij hawm teb thiab qhov tseeb ntawm electrode nyob ntawm ntau yam. Kev ntsuas ntawm pH qhov tseem ceeb thiab qhov kub thiab txias lossis qis conductivity muaj lub sij hawm teb ntev dua li kev ntsuas ntawm chav tsev kub rau qhov nruab nrab pH qhov tseem ceeb hauv cov tshuaj aqueous.
3. Kuv yuav ua li cas tuav / ntxuav cov electrode?
Kev saib xyuas niaj hnub yog ib qho tseem ceeb los txuas lub neej ntawm pH electrode. Electrolyte-fillable electrodes yuav tsum tau rov ua dua nrog cov electrolyte thaum qib yuav poob qis dua qib ntawm cov qauv tshuaj. Kev saib xyuas tiv thaiv tus qauv los ntawm ntws rov qab rau hauv electrode. Tag nrho cov ntaub ntawv siv electrolyte yuav tsum tau hloov ntawm lub sijhawm tsis tu ncua (kwv yees li ib hlis ib zaug). Qhov no ua kom cov electrolyte tshiab thiab tsis crystallize thaum lub sij hawm ntsuas vim evaporation los ntawm qhib qhov chaw nres nkoj. Nws yog ib qho tseem ceeb los xyuas kom meej tias cov pa npuas tsis tsim nyob rau hauv lub electrode, tshwj xeeb tshaj yog nyob ze ntawm cov kua complex. Yog tias qhov no tshwm sim, qhov ntsuas ntsuas yuav tsis ruaj khov. Txhawm rau tshem tawm cov npuas npuas, maj mam co lub electrode zoo ib yam li koj xav tau tus pas ntsuas kub.
Txhawm rau ntxuav cov electrodes, yaug lawv nrog dej deionised tom qab txhua qhov ntsuas, tab sis tsis txhob so nrog cov ntaub so ntswg. Qhov saum npoo ntawm daim ntawv phuam tuaj yeem khawb thiab ua rau cov pH rhiab iav daim nyias nyias, tshem tawm cov gel txheej, thiab tsim kom muaj qhov zoo li qub ntawm cov electrode. Cov nqi hluav taws xob no tuaj yeem ua rau lub ntsuas ntsuas ntsuas tsis ruaj khov. Kev ua haujlwm tu tshwj xeeb yuav tsum tau ua tom qab kis tau qee yam qauv.
