Fluoride Ion-Selective Electrode (ISE) wani firikwensin lantarki ne mai ƙwarewa kuma abin dogaro wanda aka ƙera don auna aikin fluoride ion (F⁻) kai tsaye a cikin ruwan da ke cikinsa. Ya shahara saboda zaɓinsa na musamman kuma kayan aiki ne na yau da kullun a fannin nazarin sinadarai, sa ido kan muhalli, kula da tsarin masana'antu, da lafiyar jama'a, musamman don inganta fluoride a cikin ruwan sha.
Tushen lantarki wani membrane ne mai ƙarfi wanda yawanci ya ƙunshi lu'ulu'u ɗaya na lanthanum fluoride (LaF₃). Idan aka haɗu da wani magani, ions na fluoride daga samfurin suna hulɗa da layin lu'ulu'u, suna samar da ƙarfin lantarki mai aunawa a fadin membrane. Wannan ƙarfin, wanda aka auna akan electrode na ciki, yana da daidaiton logarithmically ga aikin ion na fluoride bisa ga lissafin Nernst. Muhimmin sharadin don aunawa daidai shine ƙara Cikakken Tsarin Daidaita Ƙarfin Ionic (TISAB). Wannan maganin yana aiki da ayyuka uku masu mahimmanci: yana kula da pH mai ɗorewa (yawanci kusan 5-6), yana gyara asalin ionic don hana tasirin matrix, kuma yana ɗauke da sinadarai masu rikitarwa don 'yantar da ions na fluoride waɗanda cations suka ɗaure kamar aluminum (Al³⁺) ko ƙarfe (Fe³⁺).
Babban fa'idodin fluoride electrode sune kyakkyawan zaɓinsa akan sauran anions na yau da kullun, kewayon motsi mai faɗi (yawanci daga 10⁻⁶ M zuwa mafita mai cikewa), amsawa mai sauri, tsawon rai, da ƙarancin kuɗin aiki. Yana ba da damar yin bincike cikin sauri ba tare da shirye-shiryen samfuri masu rikitarwa ko reagents masu launi ba. Ko ana amfani da shi a cikin mitoci masu ɗaukuwa don gwajin filin, masu nazarin benchtop na dakin gwaje-gwaje, ko kuma an haɗa shi cikin tsarin sa ido ta kan layi, fluoride ISE ya kasance hanyar da aka fi so don ƙididdige fluoride daidai, inganci, da ci gaba.
