Otomatiki Kjeldahl nitrogen yekumisikidza chiridzwa basa basa:
Mashandiro anoshanda akaitwa muyedza bvunzo sampu ndeaya anotevera: dilution, reagent yekuwedzera, distillation, titration, effluent discharge, mhedzisiro kuverenga, kudhinda.
Dilution: bvisa sampu yakagayiwa muchubhu yekugaya nemvura yakasvibiswa.
Wedzera reagents: kusanganisira lye, boric acid absorption solution, titrating acid.
Distillation: Pfuura sample muchubhu yekugayira muchipfunga chinopisa kuti chipfuure kunze kweammonia gasi mumuenzaniso.
Titration: Titration yemhinduro yakanyudzwa panguva kana mushure mekuita distillation.
Dhonza mvura: dhonza mvura inorasa kubva muchubhu yekugaya uye mukombe wekugamuchira.
Verenga uye printa: verenga uye printa mhedzisiro zvinoenderana nekushanda.
Sample test process:
(1) Isa chiridzwa uye batanidza pombi.
(2) Vhura iyo condensate, isa chubhu isina chinhu yekugaya, vhura chiridzwa chekutanga mhepo yemhepo ye5 ~ 10min, chenesa pombi, kuitira kuti mvura inoyerera igadzikane.
(3) Isa iyo digestive chubhu ine digestive fluid uye isa inowirirana paramita uye mabasa usati watanga bvunzo. Iyo chaiyo-nguva yekuona basa inogoneswa panguva imwe chete. Wedzera boric acid absorption solution, dilute mvura uye lye mune otomatiki Kjeldahl apparatus; Iyo ammonia inogadzirwa ne steam distillation inotorwa ne condensation ne boric acid uye yobva yatitrated ne standard acid.
(4) Kuedza kwapera uye mhedzisiro inoratidzwa. Inogona kudhinda, kurasa tsvina uye kuchenesa otomatiki. Iyo yekutanga parameter yekuisa skrini inoratidzwa.
