1. Ntau tus neeg tuaj tshiab rau ob hom khoom no yooj yim ua rau cov purifiers thiab cov centrifuges tau yooj yim nkag siab- tom qab tag nrho, lawv ob leeg zoo li "huv khoom." Txawm li cas los xij, yog tias koj rhuav tshem lawv cov qauv kev ua haujlwm, koj yuav pom tias lawv ua raws li cov txheej txheem thev naus laus zis sib txawv.
2. Purifiers: tsom rau impurities
Lub hom phiaj ntawm purifier yog ib qho lus: txhawm rau txhim kho purity. Txawm hais tias nws yog cov pa roj lossis cov kua dej, nws lub hom phiaj yog ib txwm nyob ntawm "cov impurities" nyob rau hauv, thiab nws tshem tawm lawv xaiv los ntawm kev siv lub cev lossis tshuaj.
Kev siv thev naus laus zis feem ntau suav nrog kev siv cov khoom siv adsorbents (xws li cov pa roj carbon activated lossis molecular sieves) los ntes cov dej noo, roj, thiab CO₂; siv ion pauv resins los hloov cov hlau ions hauv cov kua; los yog, raws li pom nyob rau hauv laboratory acid purifiers, siv thermal tawg mus evaporate thiab ces condense, txo hlau impurities los ntawm 10 ppb mus rau hauv qab 0.01 ppb.
Cov ntawv thov raug kuj tseem ncaj nraim: cov kab ntau lawm semiconductor xav tau siab -purity nitrogen ntau dua 99.9999%, thiab ICP- kev tshuaj ntsuam MS muaj cov cai nruj rau cov kua qaub ultrapure. Hauv cov xwm txheej no, purifiers yog ib qho kev xaiv tsis tseem ceeb.
3. Centrifuges: tsom rau qhov ntom ntom
Lub ntsiab lus tseem ceeb ntawm lub centrifuge yog kev sib cais ntawm lub cev - siv lub zog centrifugal uas tsim los ntawm siab - kev sib hloov ceev kom cais cov khoom sib txawv ntawm qhov sib txawv thiab qhov ntau thiab tsawg. Nws tsis yog lub hom phiaj rau "purify" ib theem tshwj xeeb tab sis theej cais cov khoom hauv qhov sib tov.
Qhov piv txwv zoo tshaj plaws yog lub tshuab ntxhua khaub ncaws lub voj voog: dej ntws tawm, thaum cov khaub ncaws tseem nyob. Nyob rau hauv ib qho kev lag luam nplai, tib lub ntsiab cai siv rau kev sib cais cov hlwb los ntawm fermentation broth, extracting qab zib los ntawm mis nyuj, thiab sau plasma los ntawm cov ntshav.
Tus nqi tseem ceeb ntawm lub centrifuge yog nyob rau hauv "kev sib cais," tsis yog "purification." Yog tias koj xav tau rov qab cov hlwb, lub cev qhuav dej, lossis faib cov khoom raws li qhov loj me, lub centrifuge yog lub cuab yeej zoo.
4. Kev sib xyaw ua ke ntawm Purifiers thiab Centrifuges
Ib qho bio- txheej txheem fermentation ua haujlwm zoo li no: ua ntej, cov hlwb raug cais tawm sai sai ntawm cov kua txiv hmab txiv ntoo uas siv lub centrifuge; yog tias me me -molecule impurities tseem nyob hauv cov kua zaub, nws yog tom qab ntawd ntxiv purified siv lub purifier. Kev sib xyaw ntxhib sib cais nrog kev ua kom huv si zoo dua li siv ob txoj kev ib leeg.
5. Cov txheej txheem xaiv
Cov ntsiab lus ntawm cov khib nyiab siab (tshaj li 10%), qhov loj me me, xav tau lub cev qhuav dej sai → Centrifuges yog qhov kev xaiv zoo tshaj; tus qauv tshwj xeeb nyob ntawm cov khoom siv yam ntxwv.
Cov ntsiab lus tsawg tsawg heev (<1%), fine particle size (<5μm), high viscosity → Tubular centrifuges are more suitable for these conditions.
Cov khoom lag luam yog siab -purity gas lossis ultrapure reagent → Purifiers yog qhov kev xaiv zoo tshaj.
