Ii-electrode ze-PH ziyahluka ngeendlela ezininzi;ukusuka kwimilo yencam, isiphambuka, imathiriyeli kunye nokuzaliswa.Umahluko ophambili kukuba ingaba i-electrode ine-junction eyodwa okanye kabini.
Zisebenza njani ii-electrode ze-pH?
Udibaniso lwe-pH electrode lusebenza ngokuba nesiqingatha seseli (i-AgCl egqunywe ngocingo lwesilivere) kunye nereferensi yesiqingatha seseli (Ag/AgCl ireferensi yocingo lwe-electrode), la macandelo mabini kufuneka adityaniswe kunye ukuze agqibezele isekethe ukuze imitha ifumaneke. ukufunda pH.Ngelixa isiqingatha seseli semvakalelo siva utshintsho kwi-pH yesisombululo, isiqingatha seseli yereferensi siseno esizinzileyo.I-Electrodes ingaba lulwelo okanye ijeli izaliswe.I-electrode ye-junction ye-liquid idala i-junction kunye nefilimu encinci yokuzalisa isisombululo kwi-tip ye-probe.Ngokuqhelekileyo banomsebenzi wempompo ukuvumela ukuba wenze i-junction entsha yokusetyenziswa ngakunye.Bafuna ukugcwaliswa kwakhona rhoqo kodwa banikezela ngeyona ndlela isebenzayo eyandisa ubomi babo bonke, ukuchaneka kunye nesantya sokuphendula.Ukuba sigcinwe isiphambuka solwelo siya kuba nobomi obungunaphakade obusebenzayo.Ezinye ii-electrode zisebenzisa ijeli ye-electrolyte ekungeyomfuneko ukuba igqitywe ngumsebenzisi.Oku kubenza babe lolona khetho lwasimahla ngakumbi kodwa luyakunciphisa ubomi be-electrode ukuya malunga nonyaka om-1 ukuba igcinwe ngokuchanekileyo.
I-Junction ephindwe kabini - ezi electrode ze-pH zinebhulorho yetyuwa eyongezelelweyo ukukhusela ukuphendula phakathi kwesisombululo sokuzalisa i-electrode kunye nesampuli yakho enokuthi ibangele umonakalo kwi-electrode junction.Kufuneka bavavanye iisampulu eziqulethe iiproteni, isinyithi esinzima okanye i-sulphides
ISingxulo esiNye – ezi zezenjongo jikelele yezicelo zeesampulu ezingayi kuvala isiphambuka.
Loluphi uhlobo lwe-pH electrode ekufuneka ndilusebenzisa?
Ukuba isampulu ineeprotheyini, iisulphites, isinyithi esinzima okanye i-TRIS buffers i-electrolyte inokusabela kunye nesampulu kwaye yenze i-precipitate eqinileyo evala ukudibana kwe-porous ye-electrode kwaye iyimise ukusebenza.Le yenye yezona zizathu zixhaphakileyo ze "electrode efileyo" esiyibonayo amaxesha ngamaxesha.
Kwezo sampuli ufuna ukuhlangana kabini - oku kubonelela ngokhuseleko olongezelelweyo kule nto yenzekayo, ke uya kufumana ubomi obungcono kakhulu ngaphandle kwe-pH electrode.
