I-titrator enokwenzeka ngokuzenzekelayo ineendlela ezininzi zokulinganisa ezifana ne-dynamic titration, i-volume titration elinganayo, i-end point titration, i-PH yokulinganisa, njl njl. .
Okokuqala, thabatha i-ph electrode kwisisombululo samanzi se-kcl egcweleyo, uhlambe ngamanzi adibeneyo kwaye uyisule, uze ufake i-pipette emanzini adibeneyo, kwaye ufake i-burette kwibhotile yamanzi enkunkuma.Cofa "iiparamitha" kwi-interface yeprogram yokusebenza ukuseta iiparamitha, kwaye ulungiselele izicwangciso ngokwemfuno yakho yemeko ye-titration.Vula amandla omkhosi kunye ne-agitator ye-titrator enokwenzeka ngokuzenzekelayo, kwaye uqale inkqubo yokusebenza, emva koko ucofe iqhosha elithi "thumela" kwiphepha lokusebenza, faka ivolumu kwaye ucinezele "thumela" ukuzalisa umbhobho ngolwelo.Khangela ukuba akhona amaqamza, ukuba akhona, faka inaliti yeqamza kwiluphu ukufunxa igesi.Emva koko faka i-pipette kwisisombululo esiqhelekileyo, faka i-burette kwisisombululo sokuvavanya, ngexesha elifanayo, ubeke isisombululo sokuvavanya kwi-agitator kwaye ubeke phantsi i-bar bar, faka i-pH electrode ehlanjwe kwisisombululo sovavanyo, kwaye wenze i-electrode. ithiphu Gxila kulwelo.
Ngeli xesha, isixhobo sizoba ijika kwiscreen ngelixa sibhala ititrating.Emva kwe-titration, isixhobo sibala ngokuzenzekelayo umthamo we-endpoint, i-endpoint potential and concentration of the liquid to be measure.Emva kokuba umlinganiselo uphelile, khupha i-electrode, uyihlambulule kwaye uyibuyisele kwi-kcl egcweleyo yolwelo ukuze isetyenziswe kamva, cima i-titrator kunye namandla ekhompyutheni.Utyando lufikelela esiphelweni.
Xa usebenzisa i-titrator enokwenzeka ngokuzenzekelayo, kuyimfuneko kakhulu ukuqinisekisa ukuthembeka kwesisombululo se-buffer.Musa ukuxuba isisombululo se-buffer ngokungalunganga, kungenjalo umlinganiselo uya kuba ungachanekanga.Emva kokususa isigqubuthelo se-electrode, thintela ibhalbhu yeglasi ebuthathaka ye-electrode ekudibaneni nezinto eziqinileyo, kuba nawuphi na umonakalo okanye idlelo liya kubangela ukuba i-electrode ingaphumeleli.Ukubhekisela kwangaphandle kwe-electrode edibeneyo, kufuneka kuhlale kuqatshelwe ukuba isisombululo se-potassium chloride egcweleyo kunye ne-replenisher inokongezwa ukusuka kumngxuma omncinci phezulu kwe-electrode.I-electrode kufuneka igwenywe ukucwiliswa kwexesha elide emanzini adibeneyo, isisombululo seprotheni kunye nesisombululo se-acidic fluoride, kwaye i-electrode kufuneka igweme ukudibanisa neoli ye-silicone.
