Qaphelas ukusetshenziswa kwe-chloride ion electrode
1. Ngaphambi kokusetshenziswa, cwilisa ku-10-3M isixazululo se-sodium chloride sokusebenza ihora elingu-1. Bese ugeza ngamanzi enziwe i-deionized kuze kube yilapho inani elingenalutho lingaba ngu-+300mV.
2. I-electrode eyireferensi iwuhlobo lwe-Ag/AgCl oluphindwe kabiliuxhumano lwe-liquidireferensi. Ibhuloho likasawoti eliphezulu ligcwele 3.3I-MKCI (ri-einforcement silver chloride saturation) kanye nebhuloho eliphansi likasawoti ligcwele i-0.1M sodium nitrate. Ukuze uvimbele isisombululo sereferensi ekuvuzeni ngokushesha okukhulu, sicela uvale imbobo yokugcwalisa nge-adhesive tape ngemva kokungeza isisombululo isikhathi ngasinye.
3. I-electrode izovimbela i-diaphragm kusuka ukuklwejwaor ongcolile. It akufanele isetshenziswe isikhathi eside kusisombululo se-ion ye-chloride ephezulu ukugwema ukugqwala kwe-electrode membrane. Uma indawo yefilimu ebucayi igqokile noma ingcolisiwe, izopholishwa emshinini wokupholisha ukuze ibuyekeze indawo ebucayi.
4. Ngemuva kokusetshenziswa, kufanele ihlanzwe ibe yinani elingaba khona elingenalutho, yomiswe ngephepha lokuhlunga futhi igcinwe kude nokukhanya.
5. Ikhondakta kufanele igcinwe yomile.
