Umgaqo Wokusebenza
Iisensa zeoksijini ezinyibilikisiweyo zePolarographic zisebenza ngokusekelwe kwimigaqo ye-electrochemical, ikakhulu zisebenzisa i-Clark electrode. Isensa ine-cathode yegolide, i-anode yesilivere, kunye ne-electrolyte ethile, zonke zivaliwe yi-membrane ekhethiweyo enokuwela.
Ngexesha lokulinganisa, ioksijini iyasasazeka nge-membrane iye kwi-sensor. Kwi-cathode (i-electrode yegolide), ioksijini iyancitshiswa, ngelixa kwi-anode (i-electrode yesilivere), kwenzeka i-oxidation. Le nkqubo ivelisa umsinga wokusasazwa ohambelana noxinzelelo lweoksijini enyibilikisiweyo kwisampuli, nto leyo eyenza ukuba kulinganiswe ngokuchanekileyo.
