Xov Xwm - Qhov txawv ntawm ib qho thiab ob chav pH electrode yog dab tsi?

Cov electrodes PH sib txawv ntawm ntau txoj kev; los ntawm cov duab ntawm lub hau, qhov sib txuas, cov khoom siv thiab qhov sau. Qhov sib txawv tseem ceeb yog seb lub electrode puas muaj ib qho lossis ob qhov sib txuas.

Cov pH electrodes ua haujlwm li cas?
Cov electrodes pH ua ke ua haujlwm los ntawm kev muaj ib nrab-cell sensing (AgCl npog hlau nyiaj) thiab ib nrab-cell siv (Ag/AgCl siv electrode hlau), ob lub Cheebtsam no yuav tsum tau koom ua ke kom ua tiav ib lub voj voog kom lub 'meter' tau txais kev nyeem pH. Thaum lub cell ib nrab sensing hnov qhov kev hloov pauv hauv pH ntawm cov kua, lub cell ib nrab siv yog lub peev xwm siv tau ruaj khov. Cov electrodes tuaj yeem yog kua lossis gel puv. Lub electrode sib txuas kua tsim ib qho sib txuas nrog ib zaj duab xis nyias ntawm cov kua sau ntawm qhov kawg ntawm lub probe. Lawv feem ntau muaj lub zog twj tso kua mis kom koj tsim ib qho sib txuas tshiab rau txhua qhov kev siv. Lawv xav tau kev rov ntim tsis tu ncua tab sis muab kev ua tau zoo tshaj plaws ua rau lub neej ntev dua, qhov tseeb thiab qhov ceev ntawm kev teb. Yog tias khaws cia, qhov sib txuas kua yuav muaj lub neej ntev mus ib txhis. Qee cov electrodes siv cov electrolyte gel uas tsis tas yuav tsum tau ntxiv los ntawm tus neeg siv. Qhov no ua rau lawv yog qhov kev xaiv yooj yim dua tab sis nws yuav txwv lub neej ntawm electrode rau kwv yees li 1 xyoos yog tias khaws cia kom raug.

Ob Chav Sib Txuas - cov electrodes pH no muaj ib lub choj ntsev ntxiv kom tiv thaiv kev sib xyaw ntawm cov kua electrode thiab koj cov qauv uas yuav ua rau puas tsuaj rau qhov sib txuas electrode. Lawv yuav tsum tau kuaj cov qauv uas muaj cov protein, cov hlau hnyav lossis cov sulfides.

Kev Sib Tshuam Ib Zaug - cov no yog rau cov ntawv thov dav dav rau cov qauv uas yuav tsis thaiv qhov kev sib txuas.

Kuv yuav tsum siv hom pH electrode twg?
Yog tias ib qho qauv muaj cov protein, sulphites, cov hlau hnyav lossis TRIS buffers, cov electrolyte tuaj yeem ua rau cov qauv thiab tsim cov khoom khov uas thaiv qhov sib txuas ntawm lub electrode thiab ua rau nws tsis ua haujlwm. Qhov no yog ib qho ntawm cov laj thawj feem ntau ntawm "lub electrode tuag" uas peb pom ntau zaus.

Rau cov qauv ntawd koj xav tau ob txoj kev sib txuas - qhov no muab kev tiv thaiv ntxiv rau qhov no tshwm sim, yog li koj yuav tau txais lub neej ntev dua ntawm lub pH electrode.
