Gabatarwar na'urar Kjeldahl ta atomatik

Atomatik Kjeldahl nitrogen kayyade kayan aikiaiki aiki:

Ayyukan aikin da aka yi a cikin samfurin gwajin kayan aiki sune kamar haka: dilution, ƙarin reagent, distillation, titration, zubar da ruwa, lissafin sakamako, bugu.

Dilution: tsoma samfurin narkewa a cikin bututun narkewa tare da ruwa mai narkewa.

Ƙara reagents: ciki har da lye, maganin sha na boric acid, titrating acid.

Distillation: Sanya samfurin a cikin bututun narkewa a cikin tururi mai zafi don fitar da iskar ammonia a cikin samfurin.

Titration: Titration na maganin da aka sha yayin ko bayan distillation.

Zubar da ruwa: zubar da sharar ruwa daga bututun narkewa da kofin karba.

Yi ƙididdigewa da bugawa: ƙididdigewa da buga sakamakon bisa ga aiki.

Tsarin gwajin samfurin:

(1) Shigar da kayan aiki kuma haɗa bututun.

(2) Bude condensate, sanya bututun narkewa mara komai, buɗe kayan aikin tururi na farko na iska na 5 ~ 10min, tsaftace bututun, don kwararar tururin ruwa ya tabbata.

(3) Sanya bututun narkewa mai ɗauke da ruwa mai narkewa kuma saita sigogi da ayyuka masu dacewa kafin fara gwajin. Ana kunna aikin gano ainihin lokaci a lokaci guda. Ƙara maganin sha na boric acid, tsarma ruwa da lye cikin na'urar Kjeldahl ta atomatik; Ammoniya da aka samar ta hanyar distillation na tururi ana shayar da shi ta hanyar daɗaɗɗen ruwa tare da boric acid sannan a sanya shi da daidaitaccen acid.

(4) Gwajin ya ƙare kuma an nuna sakamakon. Yana iya bugawa, fitar da sharar gida da tsaftacewa ta atomatik. An nuna allon shigar da siga na farko.
