Ungasikhetha kanjani isihlungi esifanele sesirinji sokulungiswa kwesampula yakho?

AIsihlungi sesirinjingumkhiqizo osuselwa ku-membrane ewusizo ekususweni kokungcola okuthile, kufaka phakathi ukungcoliswa kwamagciwane kusuka kumasampula aketshezi. Izihlungi zesirinji zivame ukusetshenziselwa ukuhlunga okusebenzayo futhi okusheshayo, inzalo, kanye nokuhlanzwa kwezinto ezibonakalayo ezindaweni eziningi zokucwaninga.

Ufuna ukwazi ulwazi oluphelele mayelana nesihlungi se-syrinji, sicela uhlole le ndatshana:Umhlahlandlela ophelele wokuhlunga kwesirinji: Izici, Ukukhetha, Intengo, kanye nokusebenzisa

Zonke izinqubo zokuhlaziya lapho kuphoqeleka khona isampula yesampula yesampula kubaluleke kakhulu. Ngisho nephutha elincane lingathinta inqubo yonke futhi ekugcineni imiphumela. Ukukhetha isihlungi esifanele sesirinji kuvumela ukuthi uthole imiphumela efanele futhi usheshise yonke inqubo yokuthola noma yokuthola isifo.

Ukukhethwa kwesihlungi esifanele sesirinji kuzo zonke izivivinyo zokuhlaziya kuwumsebenzi obalulekile. Kunezici eziningana okufanele zicatshangelwe lapho ukhetha a Isihlungi sesirinjiushikukazi. Ezinye zezinombolo ezibalulekile yilezi:

1. Ungalikhetha kanjani ububanzi bokuhlunga?

Ububanzi bokuhlunga kwesirinji buxhomeke kuvolumu yesampula elizohlungwa. Uma ivolumu yesampula enamanzi iphakeme, isihlungi kufanele sibe nobubanzi obukhulu. Izihlungi zesirinji zitholakala kumadayimitha ahlukahlukene kufaka phakathi i-4mm, 13mm, 17mm, 20mm, 25mm, 30mm, no-33mm. Amasampula amancane wevolumu (cishe i-1 ml), izihlungi ezine-4mm ububanzi asetshenziswa, ngenkathi kusetshenziswa amavolumu amakhulu (cishe ama-100 ml), izihlungi ezinama-30mm ubukhulu.

2. Ungalukhetha kanjani ulwelwesi olufanele Isihlungi sesirinjiushikukazi?

Mhlawumbe ukuhlukahluka okunethonya kakhulu ekukhetheni kwakho kwesicabuso kuyinto yokufukuna ye-membrane uqobo. Uhlobo ngalunye lwe-membrane lusetshenziswa okuhlukile. Isibonelo, i-nylon imvamisa ingukuqala kokuqala kolwelwesi lwe-General Lab Filbration ngoba iyahambelana nawo womabili ama-sols anamanzi kanye ne-organic sol. Kodwa-ke, i-nylon iyabopha amaprotheni, ngakho-ke kukhona okulinganiselwe.

I-Nylon ihlukaniswa i-solvent futhi iyahambisana nawona zombili izixazululo zamanzi nama-organic, kepha akufanele isetshenziselwe ukuhlaziywa kwamaprotheni

I-PTFE imelana kakhulu namakhemikhali kanye ne-hydrophobic, ngakho-ke ilungele amasampula anamanzi, kepha hhayi amasampula we-organic

I-PVDF nayo i-solvent imelana futhi iyahambisana nawo womabili amama anamanzi kanye ne-organic sol. Ngokungafani nenalon, kunconyelwa ukuhlunga amasampula asuselwa kwi-bio ngenxa yokubopha kwawo okuphansi kwamaprotheni

I-PES ingulwelwesi oluqine ngomshini oluvame ukusetshenziselwa ukulungiswa kwesampula ye-Ion Chromatography Fass njengolunye ulwelwesi oluhlaselayo lwamaprotheni olulungele zombili izixazululo zamanzi nama-organic

I-CA iyi-membrane ephansi kakhulu ebophayo esiyinikezayo futhi ilungele amasampula asekelwe kumakhekhe, kepha hhayi ama-solvents ezi-organic

I-PP ngolunye ulwelwesi lwe-hydrophilic olungasetshenziselwa amasampula anamanzi nama-organic futhi inokuhambisana okubanzi kwamakhemikhali ngama-organic solvents

Ishadi elilandelayo lizokusiza ngokushesha ukhethe uhlobo lwe-firfile field. Kwa- Sikusize ukhethe ngokushesha uhlobo lwe-firfile membrane efanele.



Ngabe ufuna ukwazi ukuthi yisiphi isihlungi se-syrinji phakathi kwe-PVDF ne-nylon okufanele uyisebenzise, ​​hlola le ndatshana:Izihlungi zesirinji ze-PVDF vs.

3. Yimaphi osayizi we-pore ongakhetha? 0.22um noma u-0.45um?

Amasayizi asetshenziswa kakhulu ama-syricring direple pore amasayizi angu-0.2 \ 0.22 um kanye 0.45 om Isihlungi sesirinjiushikukazi, Okokucwaninga kanye nezicelo zezokwelapha.

<1. Usayizi wobumbano ozosetshenziswa ngokuvamile kunqunywa ngosayizi wezinhlayiyana ukuze uqedwe. Isibonelo, ngenhloso yokuhlunga ama-microns okuhlupha> 0,2 ama-microns ngobubanzi, bese ukhetha isihlungi se-syringe ngosayizi we-0.2-micron pore.

<2. Enye indlela yokuthola usayizi we-micron wamakholomu yi-0.45 Um Omucu> 3 Um, kanye no-0.22 um we <3um.

<3. I-0.45 membranes imvamisa isetshenziselwa ukulungiswa okujwayelekile kanye nokususwa kwezinhlayiyana ngenkathi u-0.2 \

Ufuna ukwazi okuningi mayelana nezihlungi ze-micron eziyi-0,22, sicela uhlole le ndatshana:Igayidi ephelele yokuhlunga okungu-0.22 micron: konke okudingeka ukwazi

Uma kudingeka isisombululo esinamanzi esingcolile, kukhethwa isihlungi se-sringe esilinyangweni. Okwasampula azohlunga futhi, izihlungi ezingezona eziyinyumba zingasetshenziswa.

I-aijiren tech Isihlungi sesirinjiushikukazi zinamakhodi anemibala ngokususelwa ku-membrane yokuhlunga; Ngakho-ke, uma ugcina izinhlobo eziningi zokuhlunga kwesirinji kwilebhu, ungakutshela kalula ukuthi ube nolwelwesi olufanele lwendlela yakho. Izihlungi zesirinji kukhona i-chromatography ejwayelekile esebenza ukuze ibe nelebhu yokuhlolwa kokuhlaziya. Kusetshenziswa izihlungi zesirinji kungavikela ukusetshenziswa kwakho kwe-HPLC kusuka kumazinyo ayingozi futhi kukusize wandise amathuluzi akho 'ngesikhathi.

Noma yiluphi olunye ulwazi mayelana nokuhlunga kwesirinji kwamukelwa.
