Ama-electrode e-PH ahluka ngezindlela eziningi;kusukela ku-tip shape, ukuhlangana, impahla kanye nokugcwaliswa.Umehluko oyinhloko ukuthi i-electrode ine-junction eyodwa noma kabili.
Asebenza kanjani ama-pH electrode?
Ama-electrode e-pH ahlanganisiwe asebenza ngokuba ne-half-cell (i-AgCl embozwe intambo yesiliva) kanye nereferensi yeseli (i-Ag/AgCl yereferensi yocingo lwe-electrode), lezi zingxenye ezimbili kufanele zihlanganiswe ndawonye ukuze kuqedelwe isekethe ukuze imitha ithole. ukufunda pH.Ngenkathi iseli elinguhhafu lizwa ushintsho ku-pH yesixazululo, uhhafu weseli oyinkomba unamandla okubhekisela ezinzile.Ama-Electrodes angaba uketshezi noma ijeli egcwele.I-electrode ye-liquid junction idala ukuhlangana ngefilimu encane yesisombululo sokugcwalisa ekugcineni kwe-probe.Ngokuvamile banomsebenzi wepompo wokukuvumela ukuthi udale ukuhlangana okusha kukho konke ukusetshenziswa.Badinga ukugcwaliswa kabusha njalo kodwa banikeze ukusebenza okungcono kakhulu okwandisa impilo yonke, ukunemba kanye nesivinini sokuphendula.Uma kugcinwa ukuhlangana okuwuketshezi kuzoba nempilo yaphakade esebenzayo.Amanye ama-electrode asebenzisa i-electrolyte yejeli okungadingeki ukuthi igcwaliswe ngumuntu oyisebenzisayo.Lokhu kubenza babe inketho yamahhala kodwa kuzokhawulela isikhathi sokuphila se-electrode cishe unyaka ongu-1 uma igcinwe ngendlela efanele.
I-Double Junction - lawa ma-electrode e-pH anebhuloho likasawoti elengeziwe ukuvimbela ukusabela phakathi kwesisombululo sokugcwalisa i-electrode kanye nesampula yakho ebingadala umonakalo ekuhlanganeni kwe-electrode.Kudingeka ukuhlola amasampula aqukethe amaprotheni, izinsimbi ezisindayo noma ama-sulphide
I-Single Junction - lezi ezezinjongo ezijwayelekile zezicelo zamasampuli angeke avimbe ukuhlangana.
Hlobo luni lwe-pH electrode okufanele ngilusebenzise?
Uma isampula inamaprotheni, ama-sulphite, izinsimbi ezisindayo noma amabhafa e-TRIS i-electrolyte ingasabela ngesampula futhi yakhe imvula eqinile evimba ukuhlangana okuyizimbotshana kwe-electrode futhi iyimise ukusebenza.Lesi esinye sezimbangela ezivame kakhulu ze "electrode efile" esiyibona kaninginingi.
Kulawo masampuli udinga ukuhlangana okukabili - lokhu kunikeza isivikelo esengeziwe kulokhu okwenzekayo, ngakho uzothola impilo engcono kakhulu nge-pH electrode.
