Cov khoom sib txawv ntawm cov khoom siv hluav taws xob sib txawv, uas tuaj yeem cuam tshuam qhov zoo tshaj plaws rau kev tsom xam cov tshuaj chromatography (HPLC).

Cov lus nug nquag nug txog cov tshuaj pleev pob zeb, nco ntsoov xyuas cov ntawv xov xwm no:Cov ncauj lus ntawm "txhaj tshuaj lim lim" 50 Cov Lus Nquag Nug

Qhov tseem ceeb cuam tshuam cuam tshuam particle kev kho kom tau zoo

1. Pore loj

Lub pore loj ntawm lub lim dej lim yog ib qho ntawm cov feem ntau cuam tshuam rau nws cov kev tswj hwm particle. Hom Pore qhov ntau thiab tsawg muaj:

0.22 μm stus qog Ntxaij Lim Dej: Cov ntxaij lim dej no zoo tagnrho rau cov ntawv thov uas yuav tsum tau tshem cov kab mob thiab cov khoom me me. Lawv feem ntau siv nyob rau hauv cov txheej txheem kom tsis muaj menyuam thiab rau cov lim cell kev cai xov xwm tshaj tawm. Vim lawv lub siab zoo pore loj, lawv muab theem siab ntawm particle particle, feem ntau tshaj li 98% rau cov me nyuam loj dua 0.22 μm.

0.45 μm stus qog Ntxaij Lim Dej: Cov ntxaij lim dej no haum rau kev tshem tawm dav dav, ua rau lawv xaiv cov qauv kev npaj hplc. Thaum lawv tso cai rau cov neeg lim dej nrawm dua rau 0.22 μm lim, lawv yuav tau khaws cov me nyuam tsawg dua, feem ntau yog nyob ib puag ncig loj dua 0.45 μm.

Xaiv qhov tsim nyog pore loj yuav tsum tau ntsuas kev ntsuas pom kev ua kom pom tseeb thiab txaus tus nqi. Me me muaj qhov ntau thiab tsawg uas tau ua kom tiav dua tab sis yuav qeeb qeeb ntawm cov txheej txheem pom kev.

2. Cov khoom siv lim

Cov khoom siv ntawm cov koob txhaj tshuaj Nov yog qee cov ntaub ntawv siv hauv cov koob hmoov lim dej:

Polytetrafluoroethylene (PTFE): paub rau nws cov tshuaj zoo heev,Ptfe stus qog Ntxaij Lim Dejyog tsim nyog rau kev siv tshuaj kuab thiab cov kev siv kub siab. Lawv feem ntau qhia txog cov nqi khaws cia siab, feem ntau nyob ib ncig ntawm 98-100% rau cov me nyuam loj dua 0.45 μm, ua rau lawv zoo tagnrho rau HPLC daim ntawv thov.

Nylon: Nylon stus qog Ntxaij Lim Dejyog ntau yam thiab tuaj yeem siv rau ob qho tib si aqueous thiab organic kuab tshuaj. Lawv nthuav tawm cov kev tuav pov hwm zoo tab sis yuav muaj qhov qis dua piv rau PTFE lim, tshwj xeeb yog nyob rau hauv cov dej khov kho ib puag ncig.

Polyethersulfone (Pes): Tus mov stus qog Ntxaij Lim DejYog paub rau lawv cov protein tsawg cov khoom siv, ua rau lawv haum rau kev ua piv txwv ntawm biological. Lawv muab cov kev tuav pov hwm kom zoo, feem ntau nyob ib ncig ntawm 95-98% rau 0.22 kev lim dej 0.22 μm.

Cov cellulose cellulose (RC): RC Cov tshuaj pleev thaiv hluav taws xob: RC cov tshuaj pleev thaiv cov lim dej feem ntau yog siv rau cov kev daws teeb meem aqueous thiab muab cov kev kho kom muaj kev txhim kho kom zoo. Txawm li cas los xij, kev tshawb fawb tau pom tias RC lim muaj peev xwm muaj cov lim cia qis dua, qee zaum qis li 48% rau ib feem ntawm cov particulates yuav dhau mus.

Sib xyaw cellulose Esters (MCE):Memh stus qog Ntxaij Lim Dej yog heev ntxeem thiab haum rau cov kua axes. Lawv feem ntau siv nyob rau hauv microbiological kev tshuaj xyuas vim lawv txoj kev ceev zoo ntawm cov microorganisms, tab sis lawv txoj kev sib txawv yuav sib txawv raws cov ntawv thov tshwj xeeb.

3. Lim cov taub plawv thiab tsim qauv

Qhov txoj kab uas hla ntawm cov koob txhaj tshuaj yuav ua tau tseem tuaj yeem cuam tshuam nws txoj kev ua kom rov ua tau zoo. Cov nqi hluav taws xob loj dua yuav muaj qhov sib txawv siab dua, tab sis lawv kuj tseem tuaj yeem muab faib kom nrawm dua, cuam tshuam rau kev ua kom muaj kev txhim kho tag nrho. Tsis tas li ntawd, cov qauv tsim ntawm lub lim, xws li muaj cov lim dej ua ntej lossis cov ntaub ntawv tshwj xeeb, tuaj yeem txhim kho cov particle.
