Ts'ebetso ea ts'ebetso ea sesebelisoa sa ho etsa qeto ea naetrojene ea Kjeldahl:
Ts'ebetso ea ts'ebetso e entsoeng sampoleng ea tlhahlobo ea sesebelisoa ke e latelang: ho hlapolla, ho eketsoa ha reagent, distillation, titration, effluent discharge, lipalo tsa sephetho, khatiso.
Ho hlapolla: hlapolla sampole e chekiloeng ka har'a tube ea tšilo ka metsi a hloekisitsoeng.
Eketsa li-reagents: ho kenyelletsa le lye, tharollo ea ho monya asiti ea boric, asiti ea titrating.
Distillation: Fetisa sampole ka har'a phapu ea tšilo ea lijo ka har'a mouoane o chesang ho ntša khase ea ammonia ka har'a sampole.
Titration: Titration ea mokelikeli o monyelitsoeng nakong kapa ka mor'a ho hloekisoa.
Hlakola metsi: ntša metsi a litšila ka har'a phaephe ea ho sila lijo le kopi e amohelang.
Bala le ho hatisa: bala le ho hatisa sephetho ho latela tshebetso.
Mokhoa oa ho lekola mohlala:
(1) Kenya sesebelisoa ebe u hokahanya phaephe.
(2) Bula condensate, beha tube e se nang letho ea tšilo ea lijo, bula sesebelisoa pele mouoane oa moea bakeng sa 5 ~ 10min, hloekisa phala, e le hore phallo ea mouoane oa metsi e tsitsitse.
(3) Beha tube ea tšilo ea lijo e nang le mokelikeli oa tšilo 'me u behe li-parameter le mesebetsi e tsamaellanang pele u qala tlhahlobo. Mosebetsi oa ho lemoha nako ea sebele o lumelloa ka nako e le 'ngoe. Eketsa tharollo ea boric acid absorption, hlapolla metsi le lye ka har'a lisebelisoa tsa othomathike tsa Kjeldahl; Ammonia e hlahisoang ke ho tšeloa ka mouoane e monngoa ke condensation ka boric acid ebe e tšeloa ka acid e tloaelehileng.
(4) Teko e felile 'me liphello lia bontšoa. E ka hatisa, ea lahla litšila 'me ea hloekisa ka bo eona. Skrine ea ho kenya parametha ea pele e ea hlaha.
