Qhov tseem ceeb ntawm kev ntsuam xyuas kev ntseeg siab ntawmsyringe lim

Kev lim dej feem ntau yog ib kauj ruam tseem ceeb hauv kev ua haujlwm, yog li kev ntsuas kev ncaj ncees ntawm lub syringe lim yog qhov tseem ceeb heev, thiab nws qhov tseem ceeb nyob hauv:

1. Paub meej tias qhov tseeb pom qhov pore loj ntawm daim nyias nyias

2. Xyuas seb lub lim puas zoo encapsulated

3. Kev kuaj xyuas kev puas tsuaj

4. Paub meej tias kev teeb tsa raug

5. Paub meej tias lub tshuab lim ua tiav kev ua haujlwm pov thawj

Kev ntsuam xyuas kev ncaj ncees yog peb cov khoom pov thawj thiab kev tswj xyuas zoo, uas yog lub tuam txhab cov txheej txheem kev ua haujlwm.

Dab tsi yog qhov kev ua haujlwm ntawm lubsyringe lim

Muab cov syringe pov tseg cov qauv lim uas sib xyaw cellulose membrane, nylon membrane, PVDF membrane ntawm polyvinylidene fluoride kom tau raws li cov neeg siv cov kev cai sib txawv rau lim cov qauv ntim thiab tshuaj lom neeg.

Cov txheej txheem organic / organic syringe lim tau txais PTFE (polytetrafluoroethylene) microporous membrane, uas muaj cov tshuaj zoo sib xws. Nws muaj cov tshuaj tiv thaiv zoo heev rau HPLC cov tshuaj organic xws li methanol, acetonitrile, n-hexane, isopropanol, thiab lwm yam. Soluble. Yuav siv tau los lim cov organic hnyav kuaj.

Lub lim dej / aqueous syringe siv cov polyethersulfone (PES) microporous membrane. Nws yog siv rau kev lim dej raws li cov qauv kev daws teeb meem, tsis haum rau lim cov organic hnyav piv txwv. Cov tshuaj lim dej pov tseg tso cai rau ob qho tib si aqueous thiab organic daws kom tau lim sai thiab zoo.

Syringe lim kev ua tau zoo: haum rau cov dej thiab ntau cov kuab tshuaj organic, resistant rau tag nrho cov kuab tshuaj, solubility tsawg. Nws muaj cov yam ntxwv ntawm huab cua permeability thiab dej impermeability, huab cua loj flux, siab particle retention rate, zoo kub tsis kam, tsis kam mus rau acids muaj zog, alkalis, organic solvents thiab oxidants, tsis kam mus rau aging, non-stickiness, non-flammable, non- toxicity, thiab biocompatibility. Nws cov khoom muaj feem xyuam yog siv dav hauv tshuaj, tshuaj, kev tiv thaiv ib puag ncig, hluav taws xob, khoom noj khoom haus, lub zog thiab lwm yam.

Lub hom phiaj yog dab tsisyringe lim

Lub syringe lim yog cov cuab yeej lim ceev, yooj yim thiab txhim khu kev qha uas niaj hnub siv hauv chav kuaj. Nws muaj qhov zoo nkauj zoo nkauj, lub teeb yuag thiab siab huv. Nws yog tsuas yog siv rau cov qauv prefiltration, clarification thiab tshem tawm cov hais, thiab sterilization thiab pom cov kua thiab gases. Nws yog txoj kev nyiam rau lim cov qauv me me ntawm HPLC thiab GC.Raws li txoj kev ua kom tsis muaj menyuam, nws tuaj yeem muab faib ua kom tsis muaj menyuam thiab tsis ua kom tsis muaj menyuam. Cov nram qab no editor yuav qhia koj txog lub hom phiaj ntawm lub syringe lim:

1. Tshem tawm cov protein deposits thiab kev txiav txim siab dissolution

2. Kev tshuaj xyuas dej haus thiab zaub mov thiab tshuaj xyuas biofuel

3. Qauv ua ntej kho

4. Kev soj ntsuam ib puag ncig thiab kev tshuaj xyuas

5. Kev tshuaj xyuas cov tshuaj thiab cov khoom ua kua qub

6. Cov kua roj chromatography qauv npaj thiab kev tshuaj xyuas QC tshwj xeeb

7. Gas filtration thiab kuaj kua
