Gulu ndikugwiritsa ntchito Kjeldahl Nitrogen Analyzer

I. Gulu la Nitrogen Determination Instrument

Nitrogen Determination Instrument ndi mtundu wa zida zoyesera zomwe zimagwiritsidwa ntchito kudziwa kuchuluka kwa nayitrogeni muzinthu, zomwe zimagwiritsidwa ntchito kwambiri m'magawo ambiri monga chemistry, biology, ulimi, chakudya ndi zina. Malinga ndi mfundo zosiyanasiyana zogwirira ntchito komanso mawonekedwe ogwiritsira ntchito, Nitrogen Determination Instrument imatha kugawidwa m'mitundu yosiyanasiyana.

1. Kjeldahl Nitrogen Determination Instrument:

Kjeldahl Nitrogen Determination Instrument ndi njira yakale yodziwira nayitrogeni, kutengera mfundo ya Kjeldahl reaction (njira ya Kjeldahl). Imawerengera za nayitrogeni mu zitsanzo mwa kutembenuza organic nayitrogeni mu chitsanzo kukhala ammoniacal nayitrogeni, kenako kuyamwa ammonia ndi asidi kupanga ammonium mchere, ndipo potsiriza kudziwa ammonium mchere zili ndi muyezo asidi titration. Kjeldahl Nitrogen Determination Instrument ili ndi mawonekedwe osavuta, olondola komanso odalirika, koma kusanthula kwanthawi yayitali, ndipo njira yogwiritsira ntchito sulfuric acid, alkali wamphamvu ndi ma reagents ena ndiosavuta kuwononga chilengedwe.

2. Dumas Nayitrogeni Kutsimikiza Chida:

Dumas Nitrogen Determination Instrument imagwiritsa ntchito njira yoyaka kutentha kwambiri (njira ya Dumas) kuti idziwe kuchuluka kwa nayitrogeni mu zitsanzo. Zitsanzozo zimatenthedwa pa kutentha kwakukulu m'malo a okosijeni, momwe nayitrogeni wa organic amasandulika kukhala nayitrogeni, ndiyeno zomwe zili ndi nayitrogeni zimadziwika ndi chromatography ya mpweya ndi njira zina, kuti muwerengere zomwe zili mu nayitrogeni. Dumas Nitrogen Determination imafulumira kusanthula ndipo ndi yogwirizana ndi chilengedwe chifukwa sichifuna kugwiritsa ntchito mankhwala oopsa komanso owopsa. Komabe, mtengo wa zida ndi wokwera kwambiri, ndipo zofunikira pakuwongolera zitsanzo ndizokwera.

3. Ultraviolet spectrophotometric nitrogen analyser:

UV spectrophotometric nitrogen analyzer imatengera ukadaulo wa ultraviolet spectral kusanthula kwa nayitrogeni. Nayitrogeni mu chitsanzo amachitira ndi reagents enieni kupanga mitundu mitundu, ndipo nayitrogeni zili mu chitsanzo akhoza kuwerengeredwa poyesa ultraviolet kuyamwa kwa pawiri. Mtundu uwu wa nitrogen analyzer ndi wosavuta kugwiritsa ntchito komanso wofulumira kuwunika, koma ukhoza kusokonezedwa ndi zinthu zina zomwe zili mu chitsanzo, zomwe zimakhudza kulondola kwa zotsatira.
4. Chida Chodziwikiratu cha Nitrogen:
Makina ojambulira nayitrogeni amaphatikiza ubwino wa njira zosiyanasiyana zodziwira nayitrogeni kuti akwaniritse zodziwikiratu komanso zanzeru za nayitrogeni. Kudzera muulamuliro wamakompyuta, imangomaliza masitepe a kuyeza kwachitsanzo, kuwonjezera zitsanzo, kuchita ndi kuzindikira, zomwe zimathandizira kwambiri kusanthula. Nthawi yomweyo, chowunikira cha nayitrogeni chodziwikiratu chimakhalanso ndi ntchito zosungira deta, lipoti losindikiza, ndi zina zambiri, zomwe ndizosavuta kwa ogwiritsa ntchito kuwongolera deta ndikusanthula zotsatira.

II. Kugwiritsa Ntchito Nitrogen Determination Instrument

Chowunikira cha nayitrojeni chimakhala ndi ntchito zosiyanasiyana m'magawo ambiri, zotsatirazi ndizomwe zimagwiritsira ntchito:

1. Kuyesa chitetezo chazakudya: Chida cha Nitrogen Determination chitha kugwiritsidwa ntchito pozindikira kuchuluka kwa mapuloteni muzakudya. Kupyolera mu kutsimikiza kwa nayitrogeni m'zakudya, mapuloteni amatha kuwerengeka mwanjira ina, zomwe zimapereka chidziwitso chofunikira pakuyesa chitetezo chazakudya. Kuphatikiza apo, nitrogen analyzer imatha kugwiritsidwanso ntchito kuzindikira zowonjezera muzakudya, zotsalira za mankhwala ophera tizilombo ndi zinthu zina zovulaza, kuonetsetsa chitetezo cha chakudya.

2. Kafukufuku waulimi: Pakafukufuku waulimi, mita ya nayitrojeni ikhoza kugwiritsidwa ntchito kudziwa kuchuluka kwa nayitrogeni munthaka ndi zomera. Pomvetsetsa momwe nthaka ndi zomera zimadyetsera nayitrogeni, zitha kupereka maziko asayansi a feteleza wa mbewu ndikulimbikitsa kukula ndi kukula kwa mbewu.

3. Kupanga mankhwala: popanga mankhwala, mita ya nayitrogeni ingagwiritsidwe ntchito kudziwa kuchuluka kwa nayitrogeni m'zinthu zopangira ndi zinthu. Kupyolera mu kuyang'anira nthawi yeniyeni ya kusintha kwa nayitrogeni pakupanga, magawo opangira amatha kusinthidwa munthawi yake kuti atsimikizire mtundu wazinthu komanso kupanga bwino.

4. Kuyang'anira chilengedwe: nitrogen analyzer ingagwiritsidwe ntchito ngati madzi, mpweya ndi zitsanzo zina za chilengedwe pozindikira kuchuluka kwa nayitrogeni. Pomvetsetsa kusintha kwa nayitrogeni m'zitsanzo za chilengedwe, imatha kuwunika momwe chilengedwe chimayipitsira ndikupereka chithandizo cha data pakuwunika ndi kuyang'anira chilengedwe.
