Ngwa nyocha nitrogen Kjeldahl akpaakaọrụ ọrụ:
Arụ ọrụ arụrụ n'ime ihe nlele ule ngwá ọrụ bụ ndị a: dilution, mgbakwunye reagent, distillation, titration, mkpofu mmiri, ngụkọta nsonaazụ, mbipụta.
Dilution: gbanye ihe nlele gbazere na tube digestive na mmiri distilled.
Tinye reagents: gụnyere lye, ngwọta absorption boric acid, titrating acid.
Distillation: Nyefee ihe nlele na tube mgbari n'ime uzuoku ọkụ iji kpochapu gas amonia n'ime ihe nlele.
Titration: Titration nke ngwọta etinye uche n'oge ma ọ bụ mgbe distillation gasịrị.
Wepu mmiri mmiri: kpochapu mmiri mkpofu na tube digestive na iko nnata.
Gbakọọ na bipụta: gbakọọ ma bipụta nsonaazụ dịka ọrụ siri dị.
Usoro nnwale nlele:
(1) Wụnye ngwá ọrụ ma jikọọ pipeline.
(2) Mepee condensate, tinye tube digestive na-adịghị efu, mepee ngwa ikuku mbụ maka 5 ~ 10min, hichaa pipeline, ka mmiri na-asọba na-agbasi ike.
(3) Debe tube digestive nwere mmiri digestive ma tọọ paramita na ọrụ kwekọrọ tupu ịmalite ule ahụ.Agbanyere ọrụ nchọpụta oge n'otu oge.Tinye ngwọta absorption boric acid, gbanye mmiri na lye n'ime ngwa Kjeldahl akpaka;Amonia na-emepụta site na uzuoku distillation na-etinye obi gị dum site na condensation na boric acid wee tinye ya na acid ọkọlọtọ.
(4) Nnwale ahụ agwụla ma gosipụta nsonaazụ ya.Ọ nwere ike ibipụta, wepụ ihe mkpofu ma hichaa ozugbo.Egosiri ihuenyo ntinye paramita mbụ.
