PH electrodes txawv nyob rau hauv ntau txoj kev;los ntawm lub taub hau, sib txuas, cov khoom siv thiab sau.Ib qho tseem ceeb sib txawv yog seb cov electrode muaj ib qho los yog ob qho kev sib tshuam.
Cov pH electrodes ua haujlwm li cas?
Kev sib xyaw pH electrodes ua haujlwm los ntawm kev muaj ib nrab ntawm tes (AgCl them nyiaj xaim) thiab siv ib nrab ntawm tes (Ag / AgCl siv electrode hlau), ob lub ntsiab lus no yuav tsum tau koom ua ke ua kom tiav ib lub voj voog nyob rau hauv thiaj li yuav tau txais lub meter. ib pH nyeem.Whilst qhov kev hnov ib nrab ntawm tes pom qhov hloov pauv hauv pH ntawm kev daws, qhov siv ib nrab ntawm tes yog qhov muaj peev xwm siv tau ruaj khov.Electrodes tuaj yeem ua kua lossis gel ntim.Ib qho kua hlws ris electrode tsim ib qho kev sib txuas nrog ib zaj duab xis nyias ntawm cov kua filling ntawm qhov kawg ntawm kev sojntsuam.Lawv feem ntau muaj lub twj tso kua mis tso cai rau koj los tsim kev sib tshuam tshiab rau txhua qhov kev siv.Lawv xav tau rov ua dua tsis tu ncua tab sis muab qhov ua tau zoo tshaj plaws ua rau lub neej nce ntxiv, raug thiab nrawm ntawm cov lus teb.Yog tias tswj tau cov kua dej sib txuas yuav muaj txiaj ntsig zoo nyob mus ib txhis.Qee cov electrodes siv cov gel electrolyte uas tsis tas yuav tsum tau sau los ntawm tus neeg siv.Qhov no ua rau lawv muaj kev xaiv ntau dua fuss dawb tab sis nws yuav txwv lub neej ntawm electrode mus rau kwv yees li 1 xyoo yog tias khaws cia kom raug.
Ob chav hlws ris - cov pH electrodes no muaj ib qho ntxiv ntsev choj los tiv thaiv kev cuam tshuam ntawm cov electrode sau cov tshuaj thiab koj cov qauv uas yuav ua rau muaj kev puas tsuaj rau cov electrode hlws ris.Lawv yuav tsum tau kuaj cov qauv uas muaj cov protein, hnyav hlau lossis sulfides
Ib qho kev sib tshuam - cov no yog rau kev siv dav dav rau cov qauv uas yuav tsis thaiv qhov kev sib tshuam.
Hom pH electrode kuv yuav tsum siv li cas?
Yog tias ib qho piv txwv muaj cov proteins, sulfites, cov hlau hnyav lossis TRIS buffers cov electrolyte tuaj yeem hnov mob nrog cov qauv thiab tsim cov khoom precipitate uas thaiv cov ntxeem tau ntawm cov electrode thiab nres nws ua haujlwm.Qhov no yog ib qho ntawm feem ntau ua rau "tuag electrode" uas peb pom lub sijhawm thiab sijhawm dua.
Rau cov qauv no koj xav tau ob chav sib txuas - qhov no muab kev tiv thaiv ntxiv rau qhov tshwm sim, yog li koj yuav tau txais lub neej zoo dua ntawm pH electrode.
