Nhazi na ngwa nke Kjeldahl Nitrogen Analyzer

I. Nhazi nke Ngwa Nchọpụta Nitrogen

Ngwa Nitrogen Determination Instrument bụ ụdị nnwale eji achọpụta ọdịnaya nitrogen dị n'ime ihe ndị a na-ejikarị eme ihe n'ọtụtụ mpaghara dịka kemistri, bayoloji, ugbo, nri na ihe ndị ọzọ. Dịka ụkpụrụ ọrụ dị iche iche na ọnọdụ ngwa ngwa si dị, Nitrogen Determination Instrument nwere ike kewaa n'ụdị dị iche iche.

1. Ngwa Nchọpụta Nitrogen Kjeldahl:

Ngwa Kjeldahl Nitrogen Determination Instrument bụ usoro oge gboo nke mkpebi nitrogen, dabere na ụkpụrụ nke mmeghachi omume Kjeldahl (usoro Kjeldahl). Ọ na-agbakọ ọdịnaya nitrogen dị na nlele ahụ site n'ịgbanwe nitrogen organic dị na nlele ahụ ka ọ bụrụ nitrogen amoniacal, wee na-etinye amonia na acid ka ọ bụrụ nnu ammonium, na n'ikpeazụ chọpụta ọdịnaya nnu ammonium site na ọkọlọtọ acid titration. Kjeldahl Nitrogen Determination Instrument nwere njirimara nke ọrụ dị mfe, nsonaazụ ziri ezi na nke a pụrụ ịdabere na ya, ma usoro nyocha ahụ dị ogologo, na usoro nke iji sulfuric acid, alkali siri ike na ndị ọzọ reagents dị mfe ime ka mmetọ na gburugburu ebe obibi.

2. Ngwa Nchọpụta Nitrogen Dumas:

Ngwa Dumas Nitrogen Determination Instrument na-eji usoro mgba ọkụ dị elu (usoro Dumas) iji chọpụta ọdịnaya nitrogen dị na nlele. A na-ere ihe nlele ahụ ọkụ na okpomọkụ dị elu na gburugburu ikuku oxygen, nke a na-agbanwe nitrogen organic na nitrogen, mgbe ahụ, a na-achọpụta ọdịnaya nitrogen site na chromatography gas na usoro ndị ọzọ, iji gbakọọ ọdịnaya nitrogen dị na nlele ahụ. Mkpebi Dumas Nitrogen na-eme ngwa ngwa na nyocha ma bụrụ enyi na gburugburu ebe obibi n'ihi na ọ chọghị iji reagents na-egbu egbu na nke dị ize ndụ. Otú ọ dị, ọnụ ahịa ngwá ọrụ dị elu, na ihe ndị a chọrọ maka pretreatment sample dị elu.

3. Ultraviolet spectrophotometric nitrogen nyocha:

UV spectrophotometric nitrogen analyzer dabeere na ultraviolet spectral teknụzụ nke mkpebi nitrogen. Nitrogen dị na nlele ahụ na-emeghachi omume na reagents kpọmkwem iji mepụta ogige ndị nwere agba, na ọdịnaya nitrogen dị na nlele ahụ nwere ike gbakọọ site na ịlele nnabata nke ultraviolet nke ogige ahụ. Ụdị ihe nyocha nitrogen a dị mfe iji rụọ ọrụ na ngwa ngwa iji nyochaa, mana enwere ike itinye ya na ihe ndị ọzọ dị na nlele ahụ, na-emetụta izi ezi nke nsonaazụ ya.
4. Ngwa Nchọpụta Nitrogen akpaaka:
Ihe nchọpụta nitrogen akpaaka na-ejikọta uru dị iche iche nke usoro ikpebi nitrogen iji nweta mkpebi ọdịnaya nitrogen akpaghị aka na nke nwere ọgụgụ isi. Site na njikwa kọmputa, ọ na-emecha usoro nke nlele nlele, mgbakwunye nlele, mmeghachi omume na nchọpụta, nke na-eme ka arụmọrụ nyocha dịkwuo mma. N'otu oge ahụ, onye nyocha nitrogen na-akpaghị aka nwekwara ọrụ nke nchekwa data, akụkọ mbipụta, wdg, nke dị mma maka ndị ọrụ iji mepụta njikwa data na nyocha nsonaazụ.

II. Ngwa nke Nitrogen Determination Instrument

Ihe nchọpụta nitrogen nwere ọtụtụ ngwa n'ọtụtụ mpaghara, ndị a bụ mpaghara ngwa ngwa ya:

1. Nnwale nchekwa nchekwa nri: Enwere ike iji Ngwa Nchọpụta Nitrogen mee ihe maka ikpebi ọdịnaya protein na nri. Site na mkpebi nke ọdịnaya nitrogen na nri, enwere ike ịgbakọ ọdịnaya protein na-apụtaghị ìhè, na-enye ntụaka dị mkpa maka nyocha nchekwa nri. Na mgbakwunye, enwere ike iji ihe nyocha nitrogen chọpụta ihe mgbakwunye na nri, ihe mkpofu pesticide na ihe ndị ọzọ na-emerụ ahụ, iji hụ na nchekwa nri.

2. Nchọpụta ọrụ ugbo: Na nyocha ọrụ ugbo, enwere ike iji mita nitrogen chọpụta ọdịnaya nitrogen dị na ala na anụ ahụ osisi. Site n'ịghọta ọnọdụ nri nri nitrogen nke ala na osisi, ọ nwere ike inye ntọala sayensị maka fatịlaịza ihe ọkụkụ ma kwalite uto na mmepe nke ihe ọkụkụ.

3. mmepụta kemịkalụ: na usoro mmepụta kemịkal, enwere ike iji mita nitrogen chọpụta ọdịnaya nitrogen nke akụrụngwa na ngwaahịa. Site na nleba anya n'ezie nke mgbanwe ọdịnaya nitrogen na usoro mmepụta, enwere ike ịmezi usoro mmepụta ihe n'oge kwesịrị ekwesị iji hụ na ngwaahịa ngwaahịa na mmepụta mmepụta ihe.

4. Nleba anya gburugburu ebe obibi: Enwere ike iji nitrogen analyzer mee ihe maka ịdị mma mmiri, ikuku na ihe ndị ọzọ gburugburu ebe obibi na mkpebi nke ọdịnaya nitrogen. Site n'ịghọta mgbanwe ọdịnaya nitrogen na ihe atụ gburugburu ebe obibi, ọ nwere ike nyochaa ọnọdụ mmetọ gburugburu ebe obibi ma nye nkwado data maka nlekota gburugburu ebe obibi na ọchịchị.
