PH electrode ya PH itandukanye muburyo butandukanye;uhereye kumiterere, guhuza, ibikoresho no kuzuza.Itandukaniro ryibanze ni ukumenya niba electrode ifite ihuriro rimwe cyangwa kabiri.
Nigute amashanyarazi ya pH akora?
Gukomatanya pH electrode ikora mugukora igice cya selile (AgCl itwikiriye umugozi wa feza) hamwe na kimwe cya kabiri (Ag / AgCl reference electrode wire), ibyo bice byombi bigomba guhuzwa hamwe kugirango birangize umuzenguruko kugirango metero ibone gusoma pH.Mugihe igice cya selile cyumva impinduka muri pH yumuti, icyerekezo igice cyakagari nikintu gihamye gishobora gukoreshwa.Electrode irashobora kuba amazi cyangwa gel yuzuye.Ihuriro ryamazi ya electrode ikora ihuriro hamwe na firime yoroheje yo kuzuza igisubizo kumutwe wa probe.Mubisanzwe bafite pompe yimikorere kugirango igushoboze gukora ihuriro rishya kuri buri mikoreshereze.Bakeneye kuzuza buri gihe ariko batanga imikorere myiza yongerera ubuzima, ubunyangamugayo nihuta ryibisubizo.Nibigumya guhuza amazi bizagira ubuzima bwiteka.Electrode zimwe zikoresha gel electrolyte idakenera kuzuzwa numukoresha.Ibi bituma bahitamo byinshi byubusa ariko bizagabanya ubuzima bwa electrode kugeza kumwaka 1 niba bibitswe neza.
Ihuriro Rikubye kabiri - izi electrode ya pH ifite ikiraro cyumunyu winyongera kugirango wirinde reaction hagati yumuti wuzuye wa electrode hamwe nicyitegererezo cyawe cyaba cyangiza kwangiza electrode.Barasabwa gupima ingero zirimo proteyine, ibyuma biremereye cyangwa sulfide
Ihuriro rimwe - ibi nibikorwa rusange bigenewe ingero zitazahagarika ihuriro.
Ni ubuhe bwoko bwa pH electrode nkwiye gukoresha?
Niba icyitegererezo gifite poroteyine, sulphite, ibyuma biremereye cyangwa TRIS buffers electrolyte irashobora kwitwara hamwe nicyitegererezo hanyuma igakora imvura ihamye ihagarika ihuriro rinini rya electrode ikayihagarika gukora.Iyi ni imwe mu mpamvu zitera "electrode yapfuye" tubona inshuro nyinshi.
Kuri izo ngero ukeneye guhuza kabiri - ibi bitanga uburinzi bwinyongera kubibaho, bityo uzabona ubuzima bwiza cyane muri pH electrode.
