Yuav siv cov pH meter composite electrode li cas
1. Yuav tsum tsis muaj npuas nyob rau pem hauv ntej ntawm lub teeb. Yog tias muaj npuas, lawv yuav tsum tau muab pov tseg nrog lub zog.
2. Tom qab cov electrode raug tshem tawm ntawm lub raj mis soaking, nws yuav tsum tau shaken hauv dej deionized thiab shaken qhuav. Tsis txhob so lub teeb nrog cov ntaub so ntswg. Txwv tsis pub, tus nqi electrostatic induction yuav raug xa mus rau iav zaj duab xis, uas yuav ua rau lub sijhawm ruaj khov ntawm lub peev xwm. Ib txoj hauv kev zoo dua yog siv Yaug cov electrode nrog cov tshuaj ntsuas.
3. Tom qab muab cov pH sib xyaw electrode rau hauv cov tshuaj uas yuav tsum tau ntsuas, do thiab co nws ob peb zaug ua ntej tso nws. Qhov no yuav ua kom cov lus teb ntawm electrode. Tshwj xeeb tshaj yog thaum siv lub plhaub yas pH sib xyaw electrode, lub nplawm thiab tuav yuav tsum muaj zog dua, vim tias yuav muaj kab noj me me ntawm lub teeb thiab lub plhaub yas. Tom qab cov electrode tau muab tso rau hauv qhov kev daws teeb meem, qee zaum cov roj hauv cov kab noj hniav yuav tsis raug tso tawm hauv lub sijhawm, ua rau cov npuas tsim, ua rau lub pob ua npuas lossis cov kua dej sib txuas tsis zoo nrog cov tshuaj, yog li muaj zog nplawm thiab co. yuav tsum tau tshem tawm cov npuas npuas.
4. Tom qab kuaj nyob rau hauv ib tug viscous qauv, lub electrode yuav tsum tau rinsed dua nrog deionized dej ob peb zaug kom tshem tawm cov qauv adhered rau lub iav zaj duab xis. Qee zaum nws yuav tsum tau ntxuav cov qauv nrog lwm cov kev daws ua ntej, tom qab ntawd ntxuav cov kuab tshuaj nrog dej, thiab tom qab ntawd muab tso rau hauv cov kua dej kom ua kom muaj zog.
5. Tsis txhob sib cuag nrog cov kua qaub uas muaj zog, alkalis lossis corrosive daws. Yog tias koj sim cov kev daws teeb meem zoo li no, koj yuav tsum txo lub sijhawm immersion thiab ntxuav lawv kom zoo tom qab siv.
6. Tsis txhob siv rau hauv lub cev qhuav dej xws li ethanol thiab cov concentrated sulfuric acid, uas yuav ua rau cov hydrated gel txheej ntawm qhov muag teeb.
7. Cov khoom siv plhaub ntawm lub plhaub yas pH sib xyaw electrode yog PPS. Yog hais tias lub plhaub nruab nrab ntawm electrode puas lawm, lub iav plhaub pH puas electrode yuav tsum tau siv los hloov.
