Kev siv cov tshuab hluav taws xob nitrogen hauv kev lag luam kws tshuaj

Cov khoom siv nitrogen hauv kev kho mob (nitrogen purity 99.99%) yog lub tshuab tsim nitrogen hauv kev kho mob uas tsim los ntawm GMP cov qauv raws li kev tshawb fawb thiab kev txhim kho ntawm cov tshuab tsim nitrogen siab hauv xyoo tas los no. Piv nrog rau cov hlau kheej kheej nitrogen (lossis kua nitrogen), nws muaj cov nqi khiav lag luam qis, nitrogen purity ruaj khov, thiab kev ua haujlwm yooj yim.

Cov koob dej (xws li penicillin) thiab cov tshuaj infusion loj (xws li amino acids) uas feem ntau yooj yim oxidation xav tau kev tiv thaiv nitrogen, txwv tsis pub cov tshuaj kua yooj yim oxidized thaum lub sijhawm khaws cia, uas yog, lwj. Feem ntau, ua ntej ntim, txoj kev ua ntej flushing thiab tom qab flushing (lossis flushing ib zaug) yog siv los txo cov pa oxygen concentration hauv ampoules lossis lub raj mis infusion kom qis dua 0.5%, thiab cov tshuaj tuaj yeem khaws cia tau ntev. Tam sim no, cov khoom siv uas cov chaw tsim khoom dav dav yuav yog li 5-20m ³ / h, nrog qhov huv ntawm 99.99%. Qhov sib txawv ntawm lub tshuab hluav taws xob nitrogen thiab lwm yam khoom siv nitrogen yog tias raws li tus qauv thoob ntiaj teb GMP hauv kev lag luam tshuaj, cov khoom sib cuag nrog tshuaj lossis cov tshuaj kua yog ua los ntawm stainless hlau thiab xav tau kev tua kab mob. Cov khoom siv yuav tsum tau ua los ntawm cov khoom siv tsis cam khwb cia, thiab lub cuab yeej lim dej tua kab mob tau teeb tsa ntawm qhov hluav taws xob nitrogen ntawm cov khoom siv. Tsis tas li ntawd, vim tias cov chaw tsim tshuaj muaj cov kev xav tau siab rau cov khoom siv, lawv feem ntau muaj cov qauv siab.

Lwm cov chaw tsim khoom siv raw kuj xav tau kev tiv thaiv nitrogen, thiab lawv cov txheej txheem siv nitrogen zoo ib yam li cov chaw tsim tshuaj zoo. Qhov huv huv ib txwm yog 99-99.9%, tab sis qhov ntau npaum li cas siv sib txawv nyob ntawm qhov loj ntawm lub Hoobkas, tab sis nws loj dua li qhov siv hauv cov tshuab tsim nitrogen hauv tshuaj.
