Njira ya Kjeldahl imagwiritsidwa ntchito pozindikira kuchuluka kwa nayitrogeni mu zitsanzo za organic ndi inorganic. Kwa zaka zoposa 100 njira ya Kjeldahl yakhala ikugwiritsidwa ntchito pozindikira nayitrogeni mu zitsanzo zambiri. Kutsimikiza kwa nayitrogeni wa Kjeldahl amapangidwa muzakudya ndi zakumwa, nyama, chakudya, chimanga ndi forages kuti awerengere kuchuluka kwa mapuloteni. Komanso njira ya Kjeldahl imagwiritsidwa ntchito pozindikira nayitrogeni m'madzi onyansa, dothi ndi zitsanzo zina. Ndi njira yovomerezeka ndipo imafotokozedwa m'njira zosiyanasiyana monga AOAC, USEPA, ISO, DIN, Pharmacopeias ndi European Directives.
[DRK-K616 Automatic Kjeldahl Nitrogen Analyzer] ndi njira yoyezera nayitrogeni yokhazikika yokhazikika komanso yoyezera nayitrogeni potengera njira yachikale ya Kjeldahl yodziwira nayitrogeni. Chidacho chimatha kuzindikira kukhetsa kwa zinyalala ndi ntchito yoyeretsa ya chubu chogayitsa, ndikumaliza kutulutsa zinyalala zodziwikiratu komanso ntchito yoyeretsa yokha ya kapu ya titration. Amagwiritsidwa ntchito kwambiri muzakudya, fodya, kuyang'anira zachilengedwe, zamankhwala, kafukufuku wasayansi ndi kuphunzitsa, kuyang'anira zabwino ndi zina, kutsimikiza kwa nayitrogeni kapena mapuloteni.
Mawonekedwe:
1. Kutulutsa ndi ntchito yoyeretsa yokha, kupereka ntchito yotetezeka komanso yopulumutsa nthawi. Kapangidwe ka zitseko ziwiri kumapangitsa kuti ntchitoyo ikhale yotetezeka komanso yoyera.
2. Kuthamanga kwa nthunzi kumalamuliridwa, kumapangitsa kuyesa kukhala kosavuta komanso kosavuta. Kuwunika kwanthawi yeniyeni kwa kutentha kwa distillate kumangoyimitsa ntchito ya chipangizocho pamene kutentha kwa distillate kumakhala kosazolowereka kuti zitsimikizire kulondola kwa zotsatira zoyesera.
3. Imakhala ndi ma distillation awiri kuti akwaniritse zofunikira zosiyanasiyana zoyesera, kuchepetsa kuchuluka kwa chiwawa cha acid-base reaction, ndipo mwachangu kukhetsa chubu cham'mimba kuti woyesa asakumane ndi reagent yotentha pambuyo pa distillation ndikuteteza chitetezo cha woyeserera. Pampu yolondola kwambiri ya dosing ndi dongosolo la titration zimatsimikizira kulondola kwa zotsatira zoyeserera.
4. Chiwonetsero cha mtundu wa LCD, ntchito yosavuta komanso yosavuta, yochuluka mu chidziwitso, kuthandizira ogwiritsa ntchito mwamsanga kugwiritsa ntchito chida.
5. Chidacho chimakhala ndi masensa ambiri monga chitseko cha chitetezo m'malo mwake, chubu la digestion m'malo mwake, meteor condensate, jenereta ya nthunzi, ndi zina zotero. Zonse zomwe zimayendetsedwa kuti zitsimikizire chitetezo cha kuyesera ndi woyendetsa.
6. Makina enieni a nayitrogeni odziwikiratu, odziwikiratu alkali ndi asidi kuwonjezera, distillation basi, titration basi, kutulutsa zinyalala zokha, kuyeretsa basi, kukonza basi, kukhetsa machubu amadzimadzi, kuzindikira zolakwika zokha, kuwunika kwathunthu kwa njira yothetsera, kuyang'anira kutentha kwambiri. , zotsatira zowerengera zokha.
