Taw qhia rau txoj kev siv pH meter composite electrode kom raug
⑴ Yuav tsum tsis muaj cua npuas nyob rau pem hauv ntej kawg ntawm lub teeb, yog tias muaj cua npuas, lawv yuav tsum muab pov tseg nrog quab yuam.
(2) Tom qab cov electrode raug tshem tawm ntawm lub raj mis, nws yuav tsum tau shaken hauv dej deionized thiab qhuav. Tsis txhob so lub teeb nrog ib daim ntawv phuam, txwv tsis pub lub sij hawm rau lub peev xwm stabilization yuav ntev vim lub electrostatic induction ntawm nqi hloov mus rau lub iav membrane. Ib txoj hauv kev zoo dua yog siv Yaug cov electrodes nrog cov tshuaj ntsuas.
(3) Tom qab cov pH sib xyaw electrode tau muab tso rau hauv cov tshuaj yuav tsum tau kuaj, nws yuav tsum tau nplawm thiab shaken rau ob peb zaug thiab muab tso rau statically, uas yuav ua kom cov lus teb ntawm electrode. Tshwj xeeb tshaj yog thaum siv lub plhaub yas pH sib xyaw electrode, qhov nplawm thiab tshee yog qhov hnyav dua, vim tias yuav muaj kab noj me me ntawm lub teeb thiab lub plhaub yas, thiab tom qab cov electrode tau muab tso rau hauv cov tshuaj, qee zaum cov roj hauv cov kab noj hniav yuav tsim npuas yog tias nws lig dhau lawm kom tshem tawm nws, ua rau lub pob npuas lossis cov kua dej sib txuas tsis zoo nrog kev daws teeb meem, yog li kev nplawm thiab tshee yog qhov tsim nyog kom tshem tawm cov npuas npuas.
(4) Tom qab kuaj hauv cov qauv viscous, cov electrodes yuav tsum tau muab yaug dua nrog dej deionized ob peb zaug kom tshem tawm cov qauv ua raws li cov iav membrane. Qee lub sij hawm nws yog ib qho tsim nyog los ntxuav cov qauv nrog lwm cov kev daws ua ntej, tom qab ntawd ntxuav nrog dej kom tshem tawm cov kuab tshuaj, thiab tom qab ntawd muab tso rau hauv cov kua dej kom ua kom muaj zog.
⑸ Tsis txhob sib cuag nrog cov kua qaub thiab alkali muaj zog 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.
⑹ Tsis txhob siv nws 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.
⑺ Cov khoom siv ntawm lub plhaub yas pH compound electrode yog PPS. Yog tias lub plhaub plhaub nruab nrab puas lawm, pH compound electrode nrog lub iav plhaub yuav tsum tau siv los hloov.
