ʻElekoda ʻIona Potasiuma CS6512W-SE

Wehewehe Pōkole:

Nā kikoʻī:
ʻAno: ʻElekoda koho-ion membrane PVC Pae ana: 0.04–39000 mg/L Pae mahana: 0–50 °C Ke ahonui i ke kaomi: ʻAʻole kū i ke kaomi Mea ʻike mahana: ʻAʻohe ʻAno electrode: ʻElekoda ana hoʻokahi (hoʻohana ʻia me kahi electrode kuhikuhi kūlike) Mea hale: PVC Kaula hoʻohui: PG13.5 Lōʻihi o ke kaula: 5 m a i ʻole e like me ka ʻaelike Hoʻopau kaula: I loko o ka pahu a i ʻole e like me ka ʻaelike.
ʻO ke kikowaena o kahi ISE potassium hou he membrane wai i hoʻokumu ʻia i ka polymer a i ʻole ka membrane PVC i hoʻokumu ʻia i ka valinomycin. ʻO Valinomycin, kahi ionophore kūlohelohe, hōʻike i ke koho kūikawā no nā ion potassium ma luna o nā cation maʻamau ʻē aʻe e like me ka sodium (Na⁺), he mea koʻikoʻi no nā ana pololei i nā matrices paʻakikī e like me ke koko a i ʻole nā ​​​​​​mea i unuhi ʻia e ka lepo. Hana ka electrode ma ke kumumanaʻo potentiometric: i ka wā e hoʻokomo ʻia ai i loko o kahi laʻana, ʻo ka hoʻopaʻa koho ʻana o nā ion K⁺ ma ka interface membrane-solution e hoʻopuka i kahi ʻokoʻa hiki ke ana ʻia. ʻO kēia hiki, i ana ʻia e kūʻē i kahi electrode kuhikuhi paʻa, e hahai ana i ka hoʻohālikelike Nernst a ua logarithmically proportional i ka hana ion potassium.
