Xalalka qiyaasida pH ee caadiga ah
Qalabaynta soo noqnoqda ayaa ah caadada ugu fiican ee lagu ilaalinayo saxnaanta cabbiraadda dareeraha pH/koontaroolaha, sababtoo ah cabbiriddu waxay ka dhigi kartaa akhrintaada mid sax ah oo la isku halayn karo.Dareemayaasha oo dhan waxay ku saleysan yihiin jiirada iyo dhimista ( isla'egta Nernst ).Si kastaba ha ahaatee, dhammaan dareemayaasha ayaa isbeddeli doona sida da'da.Xalka hagaajinta pH wuxuu sidoo kale kuu sheegi karaa haddii dareemehu dhaawacmo oo u baahan yahay in la beddelo.
Xalalka cabbiraadda pH ee caadiga ah waxay leeyihiin saxnaanta +/- 0.01 pH at 25°C (77°F).Sinomeasure waxay ku siin kartaa kaydiyeyaasha ugu caansan uguna badan ee la isticmaalo (4.00, 7.00, 10.00 iyo 4.00, 6.86, 9.18) oo lagu rinjiyeeyay midabyo kala duwan si si fudud loo aqoonsan karo markaad mashquul ku tahay shaqada.
Sinomeasure heerka cabbirka pH wuxuu ku habboon yahay ku dhawaad codsi kasta iyo inta badan aaladaha cabbira pH.Haddii aad isticmaalayso noocyo kala duwan oo ah kontaroolayaasha iyo dareemayaasha Sinomeasure pH, ama aad isticmaalayso mitirka pH ee benchtop ee deegaanka shaybaadhka ee noocyada kale, ama mitirka pH ee gacanta lagu qabto, pH buffers ayaa laga yaabaa inay kugu habboonaato.
Xusay: Haddii aad ku cabbirayso pH muunad ka baxsan 25°C (77°F) cabbir sax ah, tixraac jaantuska dhinaca baakadka ku yaal cabbirka pH ee heerkulkaas.
