7 yam yuav tsum ua thaum siv pH ua ke electrode kom raug
(1) Yuav tsum tsis muaj cua npuas nyob rau pem hauv ntej 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 Yaug cov electrode nrog cov tshuaj los 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 los tshem tawm. Lub kaum sab xis ntawm lub teeb los yog cov kua dej sib txuas thiab cov kev daws teeb meem yog qhov tsis zoo, yog li nws yuav tsum tau ua kom muaj zog thiab shaken kom tshem tawm cov npuas npuas.
(4) Tom qab kuaj hauv cov qauv khov, cov electrode yuav tsum tau muab yaug ob peb zaug nrog dej deionized kom tshem tawm cov qauv ua raws li cov iav membrane. Qee lub sij hawm nws yuav tsum tau ntxuav cov qauv nrog lwm cov reagents ua ntej, tom qab ntawd ntxuav nrog dej kom tshem tawm cov kuab tshuaj, thiab muab tso rau hauv cov kua dej kom ua kom muaj zog.
(5) 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.
(6) Tsis txhob siv rau hauv lub cev qhuav dej xws li ethanol thiab concentrated sulfuric acid, uas yuav ua rau cov hydrated gel txheej ntawm qhov muag teeb.
(7) Cov khoom siv plhaub ntawm cov ntaub ntawv yas pH composite electrode yog polycarbonate yas (PC). PC yas yuav yaj nyob rau hauv ib co kuab tshuaj, xws li carbon tetrachloride, trichlorethylene, tetrahydrofuran, thiab lwm yam Yog hais tias cov saum toj no cov kuab tshuaj muaj nyob rau hauv lub xeem, nws yuav Electrode casing, lub sij hawm no yuav tsum tau hloov mus rau ib tug pH compound electrode nrog ib tug iav casing.
