Ukuhlukaniswa nokusetshenziswa kwe-Kjeldahl Nitrogen Analyzer

I. Ukuhlukaniswa kwe-Nitrogen Determination Instrument

I-Nitrogen Determination Instrument iwuhlobo lwemishini yokuhlola esetshenziselwa ukunquma okuqukethwe kwe-nitrogen entweni, esetshenziswa kakhulu emikhakheni eminingi efana namakhemikhali, isayensi yezinto eziphilayo, ezolimo, ukudla nokunye. Ngokwemigomo yokusebenza ehlukene kanye nezimo zokusetshenziswa, i-Nitrogen Determination Instrument ingahlukaniswa ngezinhlobo ezahlukene.

1. Kjeldahl Nitrogen Determination Instrument:

I-Kjeldahl Nitrogen Determination Instrument iyindlela yakudala yokunqunywa kwe-nitrogen, ngokusekelwe kumgomo wokusabela kwe-Kjeldahl (indlela ye-Kjeldahl). Ibala okuqukethwe kwe-nitrogen kusampula ngokuguqula i-organic nitrogen kusampula ibe i-ammoniacal nitrogen, bese imunca i-ammonia nge-asidi ukuze yakhe usawoti we-ammonium, futhi ekugcineni inqume okuqukethwe kukasawoti we-ammonium nge-acid titration evamile. I-Kjeldahl Nitrogen Determination Instrument inezici zokusebenza okulula, imiphumela enembile futhi enokwethenjelwa, kodwa umjikelezo wokuhlaziya mude, futhi inqubo yokusebenzisa i-sulfuric acid, i-alkali eqinile namanye ama-reagents kulula ukubangela ukungcoliswa kwemvelo.

2. I-Dumas Nitrogen Determination Instrument:

I-Dumas Nitrogen Determination Instrument isebenzisa indlela yokushisa ephezulu (indlela ye-Dumas) ukuze inqume okuqukethwe kwe-nitrogen kusampula. Isampula lishiswa ngezinga lokushisa eliphezulu endaweni ye-oxygen, lapho i-nitrogen yemvelo iguqulwa ibe i-nitrogen, bese okuqukethwe kwe-nitrogen kutholwa nge-chromatography yegesi namanye amasu, ukuze kubalwe okuqukethwe kwe-nitrogen kusampula. I-Dumas Nitrogen Determination iyashesha ekuhlaziyeni futhi ihambisana nemvelo njengoba ingadingi ukusetshenziswa kwezinto ezinobuthi neziyingozi. Kodwa-ke, izindleko zemishini ziphezulu, futhi izidingo zesampula zokwelashwa kusengaphambili ziphezulu.

3. Umhlaziyi we-nitrogen we-ultraviolet spectrophotometric:

I-UV spectrophotometric nitrogen analyzer isekelwe kubuchwepheshe bokuhlaziya i-ultraviolet spectral bokunqunywa kwe-nitrogen. I-nitrogen esesampulini iphendulana nama-reagents athile ukuze ikhiqize izinhlanganisela ezinemibala, futhi okuqukethwe kwe-nitrogen kusampula kungabalwa ngokulinganisa ukumunca kwe-ultraviolet kwenhlanganisela. Lolu hlobo lwe-nitrogen analyzer kulula ukuyisebenzisa futhi luyashesha ukuhlaziya, kodwa lungase luphazanyiswe ezinye izinto kusampula, kuthinte ukunemba kwemiphumela.
4. I-Automatic Nitrogen Determination Instrument:
Umtshina we-nitrogen ozenzakalelayo uhlanganisa izinzuzo zezindlela ezihlukahlukene zokunquma i-nitrogen ukuze kuzuzwe ukunqunywa kokuqukethwe kwe-nitrogen okuzenzakalelayo nokukhaliphile. Ngokulawula ikhompuyutha, iqeda ngokuzenzakalelayo izinyathelo zokukala isampula, ukuhlanganisa isampula, ukusabela nokutholwa, okuthuthukisa kakhulu ukusebenza kahle kokuhlaziya. Ngesikhathi esifanayo, i-othomathikhi ye-nitrogen analyzer nayo inemisebenzi yokugcina idatha, umbiko wokuphrinta, njll., okulungele abasebenzisi ukuphatha idatha nokuhlaziywa kwemiphumela.

II. Ukusetshenziswa kwe-Nitrogen Determination Instrument

Umtshina we-nitrogen unohlelo olubanzi lwezinhlelo zokusebenza emikhakheni eminingi, okulandelayo yizindawo zawo eziyinhloko zokusebenzisa:

1. Ukuhlolwa kokuphepha kokudla: I-Nitrogen Determination Instrument ingasetshenziselwa ukunquma okuqukethwe kwamaprotheni ekudleni. Ngokunqunywa kokuqukethwe kwe-nitrogen ekudleni, okuqukethwe kwamaprotheni kungabalwa ngokungaqondile, kunikeze ireferensi ebalulekile yokuhlolwa kokuphepha kokudla. Ngaphezu kwalokho, i-nitrogen analyzer ingasetshenziswa futhi ukuthola izithasiselo zokudla, izinsalela zezibulala-zinambuzane nezinye izinto eziyingozi, ukuze kuqinisekiswe ukuphepha kokudla.

2. Ucwaningo lwezolimo: Ocwaningweni lwezolimo, imitha ye-nitrogen ingasetshenziswa ukunquma okuqukethwe kwe-nitrogen enhlabathini nasezicutshini zezitshalo. Ngokuqonda isimo somsoco we-nitrogen enhlabathini nasezitshalweni, inganikeza isisekelo sesayensi sokuvundisa izitshalo futhi ikhuthaze ukukhula nokuthuthuka kwezitshalo.

3. Ukukhiqizwa kwamakhemikhali: enqubweni yokukhiqiza amakhemikhali, imitha ye-nitrogen ingasetshenziswa ukunquma okuqukethwe kwe-nitrogen yempahla eluhlaza kanye nemikhiqizo. Ngokuqapha ngesikhathi sangempela izinguquko zokuqukethwe kwe-nitrogen enqubweni yokukhiqiza, imingcele yokukhiqiza ingashintshwa ngesikhathi ukuze kuqinisekiswe ikhwalithi yomkhiqizo nokusebenza kahle kokukhiqiza.

4. Ukuqapha imvelo: I-nitrogen analyzer ingasetshenziselwa ikhwalithi yamanzi, umoya kanye namanye amasampula emvelo ekunqumeni kokuqukethwe kwe-nitrogen. Ngokuqonda izinguquko zokuqukethwe kwe-nitrogen kumasampuli emvelo, ingahlola isimo sokungcoliswa kwemvelo futhi inikeze ukusekelwa kwedatha yokuqapha nokuphatha imvelo.
