Lub Tshuab Loj Loj Loj Loj
Lub tshuab luam tawm khov-tshuab-tshuab ziab khaub ncaws ua haujlwm los ntawm txoj ntsiab cai ntawm sublimation, khov kho tshuaj khov, thiab tom qab ntawd nqus dej khov, kom tshem tawm cov dej. Cov khoom siv muaj cov txheej txheem txias, lub tshuab nqus tsev, cua sov system, tswj hluav taws xob thiab hluav taws xob tswj. Pretricatment suav nrog kev lim dej, kev hloov kho, pH hloov kho thiab lwm cov kauj ruam kom ntseeg tau tias cov tshuaj kom qhuav. Cov tshuab no tuaj yeem ua kom zoo tshaj plaws ntawm kev ua yeeb yam ntawm cov tshuaj, tsis txhob muaj kev tawm tsam los ntawm qhov kub thiab txias, thiab txhim kho cov tshuaj zoo.
Yam cuam tshuam rau lub sijhawm ntawm cov chaw muag tshuaj khov-kom qhuav
Lub sijhawm ntev rau khov-qhuav kws tshuaj tsis yog ib-qhov loj-haum-txhua qhov xwm txheej. Ob peb hloov pauv tuaj yeem cuam tshuam lub sijhawm, ua rau nws yog qhov tseem ceeb rau cov tuam tsev kom xav txog cov sijhawm tsim khoom.
Cov yam ntxwv khoom cov khoom lag luam ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab kom qhuav lub sijhawm ua kom qhuav. Qhov sib xyaw ua ke ntawm cov tshuaj paus, suav nrog nws cov kev txiav txim siab ntawm kev soluting thiab muaj kev cia siab, tuaj yeem cuam tshuam tau sai npaum li cas cov khoom khov kho thiab yooj yim dua nws sublimes. Cov khoom lag luam nrog cov ntsiab lus muaj zog dua feem ntau yuav tsum tau ua kom lub sijhawm ua kom qhuav dua, raws li muaj cov khoom siv ntxiv rau tshem tawm theem.
Tus thawj pib khov khov yog lwm qhov tseem ceeb. Khov khov khov khov feem ntau ua rau muaj cov muaju dej khov me me, uas tuaj yeem txuas lub sijhawm ua kom qhuav thawj theem. Hloov siab, qeeb qeeb ua tau rau cov dej khov loj uas tuaj yeem pab txhawb cov qauv dej nrawm dua tab sis tuaj yeem muaj kev puas tsuaj rau cov qauv khoom.
Lub thickness ntawm cov khoom khoom hauv vials lossis cov tais tseem cuam tshuam lub sijhawm kom qhuav. Thicker txheej yuav tsum tau siv sijhawm ntev dua rau kev hloov pauv kub thiab vapor tshem tawm, txuas ntxiv cov txheej txheem txheej txheem tag nrho. Cov tuam ntxhab sivLub tshuab ntxhua khaub ncaws khov lojYuav tsum ua tib zoo txiav txim siab cov khoom lag luam thauj khoom los ntawm kev ua kom zoo yam tsis muaj kev sib cuam tshuam zoo.
Cov kev mob ib puag ncig tsis pub dhau lub tshuab ziab khaub ncaws khov, xws li chav huv thiab lub ntsej muag kub, cuam tshuam loj dua rau cov nqi. Txo qhov kev ntsuas kub thiab siab dua txias tuaj yeem nrawm ziab tab sis yuav tsum tau sib luag tiv thaiv kev pheej hmoo ntawm kev sib tsoo lossis kev tsis txaus ntseeg. Advanced khov cov tshuab ziab khaub ncaws muaj meej los tswj cov teeb meem no, tso cai rau kev ua kom zoo ntawm cov txheej txheem kom ua tiav cov txiaj ntsig zoo.
Theem ntawm khov-kom qhuav thiab lawv cov durations
Cov txheej txheem khov-kom qhuav muaj ntawm peb theem tseem ceeb: khov, thawj lub tshuab ziab khaub ncaws. Txhua theem muaj nws tus kheej cov sijhawm ntev li cas, uas tuaj yeem sib txawv raws cov yam uas tau hais ua ntej.
Lub theem khov khov feem ntau kav ntev li ntawm 1 txog 3 teev rau cov khoom lag luam feem ntau. Thaum lub sij hawm theem no, cov khoom siv tau txias hauv qab nws eutectic taw tes, ua kom tiav solerification. Kev siv cov tswv yim nucleation hauv niaj hnub noLub tshuab ntxhua khaub ncaws khov lojtuaj yeem pab ua qauv ua cov dej khov ua lead ua, muaj feem txo lub sijhawm khov thiab txhim kho batchency.
Thawj qhuav, lossis sublimation, feem ntau yog theem ntev tshaj plaws ntawm cov txheej txheem. Nws tuaj yeem nyob txhua qhov chaw ntawm 248 teev rau cov kws ua lag luam kws tshuaj. Txawm li cas los xij, cov kev ua kom muaj ntshauv ntau lossis cov kev daws teeb meem tseem xav tau ntau lub sijhawm ua kom qhuav, qee zaum txuas ntxiv mus rau 72 teev lossis ntau dua. Cov theem no tshem tawm feem ntau ntawm cov dej los ntawm cov khoom los ntawm sublimation ntawm dej khov ncaj qha rau vapor.
Thib ob ziab, uas lub hom phiaj tshem tawm cov khoom lag luam uas zoo nkauj rau cov khoom lag luam, feem ntau yuav siv sijhawm 12 mus rau 24 teev. Qeb no muaj kev nce qib kub maj kom txhawb kev txom nyem ntawm txoj kev ua haujlwm ntawm cov dej lwg. Lub sijhawm tuaj yeem sib txawv raws li qhov xav tau cov ntsiab lus noo noo thiab cov khoom rhiab rau kev nce qhov kub.
Nyob rau hauv tag nrho, ua tiav khov-ziab lub voj voog rau cov kws tshuaj tuaj yeem muaj txij li 1 mus rau 5 hnub uas xav tau ntau lub sijhawm ntev dua. Cov tshuab ntxhua khaub ncaws khov loj yog tsim los daws cov xwm txheej txuas mus ntxiv, tswj cov xwm txheej tsis sib haum xeeb thoob plaws tus txheej txheem los xyuas kom cov khoom lag luam zoo thiab sib txawv hla cov khoom loj.
Txhim kho kom khov-qhuav lub sijhawm nrog cov cuab yeej siv siab heev
Kev nce qib hauv khov-kom qhuav thev naus laus zis tau ua rau kev txhim kho ntawm cov tshuab ziab khaub ncaws loj uas tuaj yeem txo cov sijhawm ua haujlwm thaum lub sij hawm tswj hwm lossis txhim kho cov khoom lag luam zoo. Cov niaj hnub nruab nrog comporporate ntau yam nta tsom ntawm kev ua kom zoo rau txhua theem ntawm Lyophilization txheej txheem.
Tswj tsis ua hauj lwm yog cov thev naus laus zis uas tau hloov kho qhov ua kom khov. Los ntawm kev pib ua haujlwm dej khov ib zaug dhau ntawm txhua lub vials, nws ua kom muaj kev sib xyaw ua ke hauv dej khov siv lead ua kom loj thiab xa tawm. Qhov no tsis tsuas yog txhim kho homogeneity tab sis kuj tuaj yeem txo cov sijhawm kom qhuav los txog 30%.Lub tshuab ntxhua khaub ncaws khov lojNruab nrog kev tswj hwm nucleation muaj peev xwm muaj cov tuam ntxhab lub cuab yeej muaj zog rau cov txheej txheem ua kom zoo dua.
Txhim kho cov tshuab hluav taws kub hloov kho cov tshuab khov niaj hnub pab txhawb kom nrawm dua thiab ua kom qhuav. Qee cov qauv siab siv tau hloov tshiab cov txee tsim qauv tshiab lossis cov khoom cua kub ntxiv los txhim kho kev faib khoom cua sov. Qhov no tso cai rau kev txhoj puab ntau dua yog tswj kom qhuav, muaj peev xwm ua kom lub sijhawm qhuav tas nrho yam tsis muaj kev pheej hmoo ua neeg muaj kev pheej hmoo.
Kev siv tshuab thiab txheej txheem kev ntsuas tshuaj (Pat) kev sib xyaw ua ke hauv lub tshuab ziab khaub ncaws khov kho thiab kho kom haum ntawm cov tsis muaj tseeb. Cov kab ke no tuaj yeem tshawb pom qhov kawg taw tes ntawm kev ziab thawj zaug muaj tseeb dua, tiv thaiv cov theem no tsis tsim nyog ntawm cov khoom siv hluav taws xob no. Ib qho ntxiv, lawv tuaj yeem cia li ua kom zoo dua voj voog tsis raws li cov khoom coj tus cwj pwm, ua kom muaj txiaj ntsig zoo dua thiab khov kho-kom qhuav txheej txheem.
Nruam khov kho-qhuav cov tshuab sawv cev rau kev txiav ntawm cov kws tshuaj lub lyophilization. Cov kev teeb tsa tshiab no tso cai rau kev tsis txaus siab ua cov khoom lag luam, ntau lub sijhawm ntau lawm piv rau cov txheej txheem batch. Thaum tseem nyob rau theem pib kawm thaum ntxov rau cov chaw ua tshuaj, tas mus li kom qhuav-kom qhuav rau kev txhim kho kev ua tau zoo yav tom ntej.
Kev siv kev ua qauv ntawm kev twv ua qauv thiab cov cuab yeej sim ua ke nrog cov tshuaj khov kho hluav taws xob muaj zog tuaj yeem ua kom zoo dua lub voj voog ua ntej khiav tiag. Los ntawm kev sim zoo ib yam, cov tuam txhab tuaj yeem txheeb xyuas cov txheej txheem kev ua tau zoo tshaj plaws, muaj kev txo qis kev txhim kho lub sijhawm thiab qhov kev xav tau mus sib hais.
Tag
Lub sijhawm ntawm cov txheej txheem khov-kom qhuav rau cov kws tshuaj yog ib qho nyuaj ntawm cov khoom siv, cov khoom siv tau, thiab ua cov tsis muaj peev xwm. Thaum tus neeg raug mus txog tau los ntawm 1 txog 5 hnub, kev tawm tsam ntawm qib siabLub tshuab ntxhua khaub ncaws khov lojTau qhib cov kev muaj peev xwm tshiab rau kev ua kom tau zoo dua cov kauj ruam tsim tsim. Los ntawm cov thev naus laus zis xws li kev tswj hwm kev hloov pauv, thiab cov cuab yeej siv hluav taws xob ua haujlwm siv tau lub sijhawm khov-qhuav tsis muaj cov khoom lag luam zoo. Raws li kev lag luam kev lag luam txuas ntxiv txuas ntxiv mus rau kev txhim kho kom qhuav cov txheej txheem, kom cov txheej txheem txuas ntxiv, muaj txiaj ntsig zoo ib yam nkaus.
