Ukuhlelwa kunye nokusetyenziswa kwe-Kjeldahl Nitrogen Analyzer

I. Ukuhlelwa kweNitrogen Determination Instrument

Nitrogen Determination Instrument luhlobo lwezixhobo zokulinga ezisetyenziselwa ukumisela umxholo wenitrogen kwizinto, ezisetyenziswa ngokubanzi kwiinkalo ezininzi ezifana nekhemistri, ibhayoloji, ezolimo, ukutya njalo njalo. Ngokwemigaqo yokusebenza eyahlukeneyo kunye neemeko zokusetyenziswa, iNitrogen Determination Instrument inokwahlulwa ibe ziindidi ezahlukeneyo.

1. Kjeldahl Nitrogen Determination Instrument:

I-Kjeldahl I-Nitrogen Determination Instrument yindlela ye-classical yokumisela i-nitrogen, esekelwe kumgaqo we-Kjeldahl reaction (indlela ye-Kjeldahl). Ibala isiqulatho senitrogen kwisampulu ngokuguqula initrogen ephilayo kwisampulu ibe yinitrogen yeammoniacal, emva koko ifunxe i-ammonia ngeasidi ukwenza ityuwa yeammonium, kwaye ekugqibeleni igqibe isiqulatho setyuwa yeammonium nge-acid titration eqhelekileyo. I-Kjeldahl Nitrogen Determination Instrument ineempawu zokusebenza lula, iziphumo ezichanekileyo nezithembekileyo, kodwa umjikelezo wokuhlalutya ude, kwaye inkqubo yokusebenzisa i-asidi ye-sulfuric, i-alkali enamandla kunye nezinye i-reagents zilula ukubangela ukungcola kwendalo.

2. I-Dumas Nitrogen Determination Instrument:

I-Dumas Nitrogen Determination Instrument isebenzisa indlela yokutshisa ubushushu obuphezulu (indlela yeDumas) ukumisela umxholo wenitrogen kwisampulu. Isampulu itshiswe kubushushu obuphezulu kubume be-oksijini, apho initrogen ephilayo iguqulwa ibe yinitrogen, kwaye umxholo wenitrogen ubhaqwe nge-chromatography yegesi kunye nobunye ubuchule, ukuze ubale umxholo wenitrogen kwisampulu. I-Dumas Nitrogen Determination ikhawuleza ekuhlalutyweni kwaye ihambelana nokusingqongileyo njengoko ayifuni ukusetyenziswa kwezinto ezinobuthi kunye neziyingozi. Nangona kunjalo, ixabiso lezixhobo liphezulu, kwaye iimfuno zesampulu yonyango lwangaphambili ziphezulu.

3. Umhlalutyi wenitrogen ye-ultraviolet spectrophotometric:

I-UV spectrophotometric nitrogen analyzer isekwe kwitekhnoloji yohlalutyo lwe-ultraviolet spectral yokuzimisela kwenitrogen. I-nitrogen kwisampulu iphendula kunye nee-reagents ezithile zokuvelisa iikhompawundi ezinemibala, kunye nomxholo we-nitrogen kwisampuli ungabalwa ngokulinganisa i-ultraviolet yokufunxa kwekhompawundi. Olu hlobo lwe-nitrogen analyzer lulula ukusebenza kwaye lukhawuleza ukuhlalutya, kodwa lunokuphazamiseka ngezinye izinto kwisampuli, ezichaphazela ukuchaneka kweziphumo.
4. Isixhobo sokuMisela iNitrojeni ngokuzenzekela:
I-nitrogen detector ezenzekelayo idibanisa iingenelo zeendlela ezahlukeneyo zokumisela initrogen ukuphumeza ukuzimisela komxholo wenitrogen ozenzekelayo kunye nobukrelekrele. Ngolawulo lwekhompyuter, igqibezela ngokuzenzekelayo amanyathelo ovavanyo lwesampulu, ukongezwa kwesampulu, ukusabela kunye nobhaqo, okuphucula kakhulu uhlalutyo olusebenzayo. Ngelo xesha, i-nitrogen analyzer ezenzekelayo nayo inemisebenzi yokugcina idatha, ingxelo yokushicilela, njl., ekulungele abasebenzisi ukuba baqhube ulawulo lwedatha kunye nohlalutyo lweziphumo.

II. Ukusetyenziswa kweNitrogen Determination Instrument

Isikhangeli se-nitrogen sinoluhlu olubanzi lwezicelo kwiindawo ezininzi, ezi zilandelayo ziindawo zaso eziphambili:

1. Uvavanyo lokhuseleko lokutya: I-Nitrogen Determination Instrument ingasetyenziselwa ukumisela umxholo weprotheyini ekutyeni. Ngokumisela umxholo we-nitrogen ekutyeni, umxholo weprotheyini ungabalwa ngokungathanga ngqo, ukubonelela ngesalathiso esibalulekileyo sovavanyo lokhuseleko lokutya. Ukongeza, i-nitrogen analyzer ingasetyenziselwa ukufumanisa izongezo zokutya, iintsalela ze-pesticide kunye nezinye izinto eziyingozi, ukuqinisekisa ukhuseleko lokutya.

2. Uphando lwezolimo: Kuphando lwezolimo, imitha yenitrogen ingasetyenziswa ukumisela umxholo wenitrogen emhlabeni nakwizicubu zezityalo. Ngokuqonda imeko yesondlo senitrogen yomhlaba kunye nezityalo, inokubonelela ngesiseko senzululwazi sokuchumisa isityalo kunye nokukhuthaza ukukhula nophuhliso lwezityalo.

3. Ukuveliswa kweekhemikhali: kwinkqubo yokuvelisa imichiza, imitha yenitrogen ingasetyenziselwa ukumisela umxholo wenitrogen wezinto eziluhlaza kunye neemveliso. Ngokubeka iliso ngexesha langempela lokutshintsha komxholo we-nitrogen kwinkqubo yokuvelisa, iiparamitha zokuvelisa zinokuhlengahlengiswa ngexesha elifanelekileyo ukuqinisekisa umgangatho wemveliso kunye nokusebenza kakuhle kwemveliso.

4. Ukubeka iliso kokusingqongileyo: i-nitrogen analyzer ingasetyenziselwa umgangatho wamanzi, umoya kunye nezinye iisampuli zokusingqongileyo ekumiseni umxholo we-nitrogen. Ngokuqonda utshintsho lwesiqulatho senitrogen kwiisampulu zokusingqongileyo, inokuvavanya imeko yokungcoliseka kwendalo kunye nokubonelela ngenkxaso yedatha yokubeka iliso kokusingqongileyo kunye nolawulo.
