ISE Sensor Calcium Ion Dej Hardness Electrode CS6518A Calcium Ion Electrode

Kev Piav Qhia Luv:

Lub Electrode Xaiv Qhov Nyuaj (Calcium Ion) yog ib qho tseem ceeb analytical sensor tsim los rau kev ntsuas ncaj qha thiab sai ntawm calcium ion (Ca²⁺) kev ua haujlwm hauv cov kua dej. Txawm hais tias feem ntau hu ua "hardness" electrode, nws tshwj xeeb ntsuas cov calcium ions dawb, uas yog cov neeg tseem ceeb rau qhov nyuaj ntawm dej. Nws yog siv dav hauv kev saib xyuas ib puag ncig, kev kho dej hauv kev lag luam (piv txwv li, boiler thiab txias systems), kev tsim dej haus, thiab aquaculture, qhov twg kev tswj hwm calcium kom raug yog qhov tseem ceeb rau kev ua haujlwm zoo, kev tiv thaiv cov khoom siv scaling, thiab kev noj qab haus huv ntawm lub cev.
Lub sensor feem ntau siv cov kua lossis polymer membrane uas muaj cov ionophore xaiv, xws li ETH 1001 lossis lwm cov tshuaj sib xyaw, uas feem ntau sib xyaw nrog calcium ions. Qhov kev sib cuam tshuam no tsim qhov sib txawv ntawm lub membrane piv rau lub electrode sab hauv. Lub zog ntsuas tau ua raws li Nernst equation, muab cov lus teb logarithmic rau calcium ion kev ua haujlwm hauv ntau qhov concentration (feem ntau ntawm 10⁻⁵ txog 1 M). Cov qauv niaj hnub no muaj zog, feem ntau muaj cov qauv tsim khoom siv rau kev tshuaj xyuas hauv chaw kuaj mob thiab kev saib xyuas cov txheej txheem online tas mus li.
Ib qho txiaj ntsig tseem ceeb ntawm lub electrode no yog nws lub peev xwm los xa cov kev ntsuas tiag tiag yam tsis tas siv sijhawm ntau los ntsuas cov tshuaj lom neeg ntub dej, xws li kev ntsuas complexometric. Txawm li cas los xij, kev ntsuas kom zoo thiab kev kho cov qauv yog qhov tseem ceeb. Lub zog ionic thiab pH ntawm cov qauv yuav tsum tau kho feem ntau siv cov khoom siv kho lub zog ionic tshwj xeeb / buffer kom ruaj khov pH thiab npog cov ions cuam tshuam xws li magnesium (Mg²⁺), uas tuaj yeem cuam tshuam rau kev nyeem ntawv hauv qee qhov kev tsim. Thaum tswj hwm thiab ntsuas kom zoo, lub electrode calcium ion-selective muab txoj hauv kev txhim khu kev qha, ua haujlwm tau zoo, thiab pheej yig rau kev tswj hwm qhov nyuaj thiab kev tshuaj xyuas calcium thoob plaws ntau daim ntawv thov.
