Puas muaj lub sijhawm txwv rau cov electrode rau hauv cov tshuaj thaum lub ph meter siv?
pH meter / acidometer electrode yuav tsum tau soaked ua ntej siv, vim hais tias pH meter / acidometer noob yog ib tug tshwj xeeb iav zaj duab xis, muaj ib tug nyias hydrated gel txheej nyob rau saum npoo ntawm cov iav zaj duab xis, uas tsuas tuaj yeem teb tau zoo rau H + ions hauv kev daws hauv qab. txaus ntub dej. Nyob rau tib lub sijhawm, iav electrode tom qab immersion, tuaj yeem ua rau lub peev xwm asymmetric txo qis thiab zoo li ruaj khov. pH meter / acidity meter iav electrode feem ntau tuaj yeem ua dej distilled lossis pH meter / acidity meter 4 tsis muaj kev daws teeb meem immersion. Feem ntau nws yog qhov zoo dua los siv pH meter / acidometer 4 buffer tov, thiab lub sij hawm ntub dej yog los ntawm 8 teev mus rau 24 teev lossis ntev dua, nyob ntawm qhov tuab ntawm cov iav iav zaj duab xis thiab qib ntawm kev laus ntawm electrode. Cov kua hlws ris ntawm cov ntaub ntawv siv electrode yuav tsum tau tsau. Vim tias lub peev xwm ntawm cov dej sib txuas yuav nce los yog tsis ruaj khov yog tias cov kua hleb dries tawm, cov kua dej ntawm cov khoom siv electrode yuav tsum yog tib yam li cov kev siv sab nraud ntawm cov khoom siv electrode, piv txwv li, 3.3 mol / L KCL tov los yog saturated. KCL tov, thiab lub sij hawm soaking feem ntau yog ob peb teev. Yog li ntawd, rau pH / acidometer ua ke electrodes, lawv yuav tsum tau muab tso rau hauv pH / acidometer 4 tsis muaj cov tshuaj uas muaj KCL thiaj li yuav muaj kev cuam tshuam ib txhij ntawm ob lub iav qhov muag thiab cov kua dej sib txuas. Kev saib xyuas tshwj xeeb yuav tsum tau them rau qhov tseeb tias nws tau ua raws li kev cai yav dhau los rau soak ib qho pH / acidometer iav electrodes hauv dej deionised los yog pH / acidometer 4 tsis muaj kev daws teeb meem, thiab tias txoj kev ntub dej no tseem siv thaum siv pH / acidometer compound. electrodes, thiab tseem yog misdirected nyob rau hauv cov lus qhia tsis raug rau kev siv pH / acidometer compound electrodes. Qhov txiaj ntsig ncaj qha ntawm txoj kev ntub dej tsis zoo no yog qhov ua tau zoo pH meter / acidometer electrode ua cov lus teb qeeb, tsis zoo electrode, thiab lub sij hawm ntub dej ntev dua, qhov ua tau zoo dua, vim tias tom qab lub sij hawm ntev ntawm soaking, KCL concentration. nyob rau hauv cov kua hlws ris (xws li, hauv cov xuab zeb core) tau txo qis heev, yog li cov kua hlws ris muaj peev xwm nce thiab tsis ruaj khov. Tau kawg, cov electrode yuav rov zoo dua yog tias nws rov qab los rau hauv cov kua dej kom raug rau ob peb teev.
Tsis tas li ntawd, pH meter / acidometer electrodes yuav tsum tsis txhob muab tso rau hauv nruab nrab lossis alkaline tsis daws teeb meem, vim tias qhov kev nkag mus ntev hauv cov kev daws teeb meem no yuav npub cov lus teb ntawm pH meter / acidometer iav membrane. Kev npaj ntawm qhov tseeb pH meter / acidity meter electrode soaking tov: coj pH meter / acidity meter 4. , tsim nyog cua sov, stirring kom txog thaum tag nrho yaj uas yog. Muaj cov raj mis electrode soaking tov muaj nyob rau hauv kev ua lag luam, nrog specifications ntawm 500 ml thiab 50 ml, cov soaking tov muaj preservatives, yuav tsis moldy thiab spoilage, txee lub neej ntawm ib xyoos.
Txhawm rau ua kom lub pH meter / acidometer electrode siv tau yooj yim dua, qee qhov txawv teb pH meter / acidometer electrode thiab qee qhov hluav taws xob hauv tsev, pH meter / acidometer electrode lub taub hau yog nruab nrog lub hnab yas kaw, ntim nrog electrode soaking kua, electrode taub hau rau ntev immersed nyob rau hauv uas, thaum siv los rub tawm lub ntxuav yuav ua tau, yooj yim heev. Txoj kev khaws cia no tsis yog yooj yim xwb, tab sis kuj tseem txuas ntxiv lub neej ntawm electrode kuj yog qhov zoo heev, tab sis cov yas vial ntawm cov kua dej ntub dej yuav tsum tsis txhob kis kab mob, xyuam xim rau kev hloov.
