Vim li cas thiaj siv tangential flow filtering
Cov cuab yeej siv tau yooj yim, qhov ntim tuag me me, thiab lub sijhawm ua piv txwv yog ceev. Nws tuaj yeem ua tiav sai los ntawm kev tshawb fawb thiab kev tsim kho mus rau kev tsim khoom. Piv nrog rau centrifugal concentration lossis tuag kawg pom cov cuab yeej, nws tuaj yeem tau txais cov qauv concentration siab dua hauv lub sijhawm luv.
Ua ob kauj ruam hauv tib lub cev - mloog zoo thiab percolate cov qauv hauv tib lub cev, txuag lub sijhawm thiab zam cov khoom poob.
Cov cuab yeej siv qis qis, thaj chaw me me thiab cov nqi kho mob tsawg - cov pob membrane siv nyob rau hauv tangential flow filtration system tuaj yeem siv ntau zaus lossis ib zaug; Cov khoom lag luam yog ib qho yooj yim rau kev kuaj xyuas thiab kev ntsuam xyuas kev ncaj ncees yog yooj yim los xyuas kom meej tias tsis muaj qhov tsis zoo hauv kev siv. Nws yog tshwj xeeb tshaj yog haum rau zus tau tej cov khoom muaj nqi-ntxiv roj ntsha
Tangential flow filtration txoj cai
Tangential flow filtration tseem hu ua "cross flow". Lub siab tsav cov kua dej kom dhau los ntawm qhov chaw ntawm lub lim membrane thiab ntxuav tawm cov ntxiab molecules, uas zoo heev txo cov concentration polarization; Cov kuab tshuaj thiab cov kuab tshuaj molecules nrog lub siab tsawg dua qhov pore loj ntawm daim nyias nyias yog tsim rau ntawm ob sab ntawm daim nyias nyias, thiab cov loj dua qhov pore loj ntawm daim nyias nyias rov qab mus rau qhov qub tov rau ntau lub voj voog kom tiav cov concentration thiab sib cais; Nyob rau hauv tuag kawg pom (DC pom), pom lub siab yog nce, lub concentration polarization yog ib qho yooj yim rau tsim ntawm daim nyias nyias, qhov sib cais ceev yog qeeb thiab cov nyhuv tsis zoo; Nyob rau hauv sib piv, nyob rau hauv lub tangential flow filtration txheej txheem, tsim ntawm lub limiting txheej yog tiv thaiv los ntawm lub recirculation ntawm cov sib tov. Qhov kev rov ua dua no zoo ib yam li qhov kev sib cais tsis yooj yim rau kev sib sau ua ke ntawm daim nyias nyias, thiab ua rau rov ua dua, ua rau lub neej ua haujlwm ntev ntawm daim nyias nyias; Yog li ntawd, siv tangential flow filtration los cais cov biomolecules xws li cov protein, polysaccharide thiab cov khoom siv ntshav muaj kev ua tau zoo dua thiab ceev dua concentration thiab sib cais ceev.
