MCE Nta: Xws li uniform pore loj, siab porosity, tsis muaj media cov khoom noj, cov nqi nyias nyias, thiab ua kom nrawm dua.

EPA Voa vials muaj kev nyab xeeb kaw lub tshuab kom coj cov qauv kev ncaj ncees thiab tiv thaiv kev ua kom tsis txhob muaj kev ua paug lossis paug. Lub vials feem ntau tuaj nrog lub hau ntswj sib npaug nrog lub septum, kom nruj thiab xau pov thawj foob. Qhov kev kaw lub tshuab kaw no ua kom cov tshuaj tiv thaiv ntawm cov organicci compounds thaum cia thiab tsheb thauj mus los.

Qhov zoo ntawm koob txhaj tshuaj lim: qhov qis dua cov membrane thiab plhaub kom ntseeg tau tias tsis muaj cov lim dej paug ntxiv rau koj cov qauv. Aijiren ua cov kev ntsuam xyuas ua tau zoo nyob rau hauv kev mob Hplc. Qhov sib xyaw 1 hli borosilicate iav Preilter (30mm ntaus ntawv) ua kom muaj kev ntseeg siab siab dua hauv cov ntsiab lus muaj txiaj ntsig zoo.

Daim nyias nyias cov ntaub ntawv tau muab rau hauv cov lag luam zoo tshaj plaws, thiab cov khoom lag luam zoo nkauj thiab muaj kuab heev nyob rau hauv cov khoom siv huv. Txhua lub cev lim dej yog HPLC ntawv pov thawj.

Aijiren¡¯s PP koob txhaj tshuaj siv cov khoom siv hydrophobic pawm, thiab yog qhov tsim nyog rau kev lim dej ntawm aqueous thiab feem ntau cov kuab tshuaj. Feem ntau siv rau lim kev kuaj, cov kuab tshuaj, dej roj ntsha, lub hydrophobic pp lim nyias nyias zoo rau cov pa roj. Cov khoom tau sterilized los ntawm qhuav tshav kub ntawm 121¡Ãc rau 15 feeb.

Vim tias lub siab hydrophobicity ntawm PVDF daim nyias nyias, nws yuav tsum tau so kom ua tiav lub hom phiaj ntawm kev ua haujlwm thiab ua kom lub ntsej muag yooj yim los khi cov proteins yooj yim dua. Cov khoom no tau sib xws nrog ntau cov dyes, xws li ponceau-s liab, sypro ruby, toluidine xiav, cups, colloidal kub, Is Nrias teb Inkamido dub. Ntawm lawv, tom qab dyeing nrog kev tuag xws li Ponceau thiab CPTs, qhov tuag tuaj yeem raug ntxuav tawm thiab cov yeeb yaj kiab tuaj yeem siv rau kev soj ntsuam ntxiv; Thaum tuag xws li Coomassie ci ntsa iab xiav, Is Nrias teb Dub, thiab kuv cov neeg tsis tuaj yeem siv, kev ua yeeb yaj kiab tsis tuaj yeem siv tom qab zas. Rau kev soj ntsuam ntxiv.

Lub hom phiaj tseem ceeb ntawm MCE: kom lim cov lus thiab cov kab mob ntawm cov kua dej, roj, siv rau cov seev cev, thiab muaj peev xwm siv tau rau kev kuaj pom ntawm cov lus thiab cov kab mob.
Polyethersulfone (PES): Hydrophilic, ruaj khov nyob rau hauv av qis, ua rau nws muaj protein tsawg, ua rau lawv muaj txiaj ntsig qis, ua rau lawv haum rau ntau aqueous thiab organic kuab tshuaj. Pes shewbranes pub cov kua dej siab dua PTFE. Kub tiv taus. Ph Pua Tau Ntau ~ 3-14 (qee zaum hais ua 1-14).

Nrog rau Pes koob hmoov Mrice lub cev met-me me, nws tuaj yeem siv cov dej ntws ntau, nrog rau cov ptfe), thiab cov protein tsawg dua. Nrog cov yam ntxwv no, pog koob lim dej muab cov kev ua tau zoo tshaj rau kev siv nrog cov qauv roj ntsha thiab kev coj noj coj ua tshaj tawm. Ua hauj lwm Ph ntau ntau ~ 3-14.

Aijiren Tech Aijiren Cov Khoom Siv Lim yog ib qho ntau ntawm cov tsis muaj kev tiv thaiv cov kua dej rau cov kev npaj ua kom zoo. Mostuctrucible membrane zoo thiab automated cov txheej txheem tsim kom meej particulates tau muab tshem tawm los ntawm txhua qhov chaw thiab kev txhaj tshuaj tiv thaiv kab thiab kev txhaj tshuaj tsawg lossis kev puas tsuaj.

Lub khauj khaum ntawm PTFE lub cev lim li yog ua los ntawm polypropylene (pp) nrog tshuaj ruaj khov zoo. Nws yog ua los ntawm cov xim sib txawv, uas yooj yim rau cov neeg siv kom paub qhov txawv ntawm cov khoom sib txawv thiab zam kev tsis meej pem. Lub lim membrane Admized Txawv Teb Chail-essest lim cov khoom lag luam zoo nkauj thiab cov khoom lag luam zoo. Nws yog qhov kev xaiv zoo tshaj plaws rau kev sim taw ntawm cov qauv. Tus qauv interface yog yooj yim rau txuas rau ntau lub koob txhaj tshuaj, thiab nws kuj tseem tuaj yeem txuas nrog lub koob ntawm 7725 valve kev siv tau ncaj qha tom qab kev lim dej.

Polyethersulfone Lim muaj cov yam ntxwv ntawm cov dej ntws siab, txo cov khoom siv tsis txaus siab, thiab ntau dua cov tshuab ua tsis kam tsis haum ntau dua li cov memule cellule. Nws yog qhov haum rau kev txheeb xyuas roj ntsha, tshuaj, kom tsis muaj menyuam thiab ua raws li kev lim dej. Daim nyias nyias yog ntim rau hauv lub plhaub polymer yam tsis tau siv cov nplaum. Txhua koog yog eto lossis gamma tshav ray sterilized thiab guaranteed ua pyrogene-dawb.

PTFE koob txhaj tshuaj PTFE yog inert rau ntau cov kuab tshuaj hnyav thiab muaj zog acids thiab alkalis. Cov koob hmoov nplej no tseem tuaj yeem raug rau qhov kub thiab yog qhov kev xaiv zoo rau kev npaj hplc qauv kev npaj. Aijiren muaj PTFE cov koob txia lim hauv lub xeev hydrophobic.

Cellulose acetate yog ib qho protein tsawg heev yog qhov zoo tagnrho rau aqueous raws cov qauv thiab kuaj cov roj ntsha. Nws yog qhov qis dua cov khoom noj muaj protein qis dua li cov polyethersulphone lossis PVDF WHALBranes, tab sis muaj cov tshuaj tsis kam tshaj tawm cov cellulose (RC). CA yog ib daim duab muaj zog thiab hydrophilic.

Cov tshuaj lim lim tau tsim los rau cov kua kom yooj yim thiab ua tau zoo thiab roj av. Lawv muaj cov koob txhaj tshuaj-nyiam nrog ib qho inlet thiab qhov hluav taws xob, tso cai rau kev txuas ncaj qha rau cov koob txhaj tshuaj lossis lwm yam kua dej. Cov ntxaij lim dej tshem tawm cov particulates, cov kab mob me, thiab cov tsis tau xav tau, kom cov qauv huv si thiab qhia meej rau kev soj ntsuam.

MCE (sib xyaw Cellulose cellulose) Cov tshuaj lom cellulose yog qhov kev xaiv zoo tshaj plaws thaum kuaj xyuas muaj kev koom tes. Sib xyaw cellulose yog lub mydrophilic membrane muaj ob qho muaj protein tsawg tus nqi thiab tshwj xeeb ntws.

Cov koob txhaj tshuaj lim dej (lossis lub log lim) yog ib qho-siv, membrane-based ntaus siv rau kev tshem tawm ntawm me me (≤) cov qauv ua kua. Xaiv raws li cov ntaub ntawv kawg uas xav tau, cov hmoov av lim tau feem ntau siv hauv kev sim ua kom nrawm thiab lim, lossis txawm tias muaj kev tsis huv.

hauv cov tshuaj chromatographic, cov qauv tso rau ntawm cov chromatographic kem rau kev soj ntsuam tom qab cov samller tau txhaj. Txawm li cas los xij, sab hauv tus tub ntxhais ntawm tus sampler thiab cov chromatographic kem yog tus nyias nyias. Yog tias muaj cov khoom loj hauv cov qauv, nws yuav ua rau cov khoom siv los thaiv, yuav tsum tau siv tshuaj txhaj lim rau kev kho kom ua ntej kev kho mob lim. <\ / p>

Lub cheeb ntawm 13MM 0.45um koob txhaj tshuaj yog 13mm, lub lim pore loj yog 0.45um, thiab lub taub lim membranrane yog PTFE. PTFE tsis tshua muaj neeg nyob hauv thiab hydrophobic. Cov neeg siv khoom tuaj yeem xaiv raws li qhov xwm ntawm cov qauv. Feem ntau hais lus, PTFE Lem membrane tuaj yeem ua tau raws li qhov xav tau ntawm kev ntsuas loj ntawm cov qauv.

Los ntawm kev siv aijiren cov koob txia lim lim tau muab tshem tawm uas tuaj yeem ua rau paug thiab txhaws ntawm cov twj paj nruag. Yog li, lim koj cov hnoos qeev ua rau nce lub neej thiab qis dua downtime ntawm cov khoom siv chromatographic thiab cov khoom siv tau zoo dua thiab yog li txuag lub sijhawm thiab nyiaj txiag.

Lub nplhaib txhawb zog tuaj yeem muab lub zog ntau dua rau lub plhaub kom tiv thaiv kom tsis txhob to tam sim no thiab tawg (30mm cov khoom lag luam siab yog nyob ntawm 120 psi). Lub plhaub yog ua los ntawm cov kuab tshuaj-resistant, tsawg-extraction polypropylene cob, xaiv tau tshwj xeeb rau kev ua kom dav dav nrog HPLC piv txwv Matrices. Txoj kev daws teeb meem tau lim ntawm qhov kub txog rau 100¡Ãc, uas yooj yim thiab yooj yim siv.

Aijiren lub cev lim dej nrog cov nylon weecbranes tau sib haum nrog ntau hom kuab tshuaj, ua rau lawv pom kev ceev ntawm cov aquouse ntau thiab cov kev daws teeb meem. Yog li ntawd, thaum muaj kev sib xyaw ntawm cov qauv AQUE AQUSING ORGANT ONTES LOS NTAWM COV LINLORT SHEES THIAB tau sib cais los ntawm cov qauv AQUALOING. Siv txoj kev no yooj yim, tag nrho cov sijhawm rho tawm yog tsuas yog 3-4 feeb; Nws yog ib puag ncig phooj ywg, tsis muaj cov nyhuv centrifugal, muab cov nqi ua kom muaj zog ntau dua los ntawm kev lim dej kom txo qis kev tsis txaus siab thiab tiv thaiv cov xim xim.
