Kev tshaj tawm yog ib txoj kev siv hluav taws xob dav dav, tshwj xeeb tshaj yog hauv cov ntawv thov cov iav, kom txo qis adsorption thiab txhim kho kev rov ua dua tshiab. Cov txheej txheem cuam tshuam nrog kev qhia methylating ntawm cov pab pawg methylating, uas yooj yim nrog cov iav saum toj ntawm cov iav saum npoo av los ua cov txheej txheem hydrophobic. Hauv qab no yog kev sib piv ntawm kev sib piv nrog lwm cov kev ua haujlwm sib luag.

Kev sib tsoo hauv silanization

Mechanism: kev tshaj tawm siv vapor deposition kom thov cov hniav nyiaj tob uas reacts nrog dawb hydroxyl (silanol) pawg ntawm iav nto. Tus txheej txheem no txo cov kev sib tsoo ntawm cov nplaim thiab lowers nws cov npoo nro, yog li ua cov qauv kev kos duab hydrophobic uas txwv tsis pub adsorption thiab leaching ntawm iav Cheebtsam.

Silanization tau txo qis cov nplaum ntawm cov nplaum ntawm polar ntawm cov protein ntau xws li cov protein thiab peptides, li kev txhim kho cov qauv rov qab thiab ntsuas kev txheeb xyuas qhov tseeb. Cov kev sib tw sib haum tsim tau tsim thaum lub sijhawm Silanization muab ib nrab txheej txheej uas tseem muaj txiaj ntsig txawm tias chav kuaj mob thiab ntau yam kev kuaj mob hauv tes dej num. Silanes thaj chaw tau paub txog lawv cov kev ruaj khov thiab ntev ntev, ua rau lawv haum rau hauv ntau cov kuab tshuaj thiab cov xwm txheej.

Cov ntawv thov: feem ntau yog siv hauv chromatography vials los txhim kho kev rov qab tshuaj xyuas kev lag luam, tshwj xeeb tshaj yog rau cov kev ntsuas tsawg.

Kimshield deactivation

Mechanism: Zoo ib yam li Silanization, Kimshaield Kev Txom Nyem yog Vapor Endition cov txheej txheem, tab sis siv cov roj silicone. Nws tseem yuav txo cov npoo nro thiab ua cov txheej hydrophobic, tab sis tej zaum yuav muab cov haujlwm sib txawv me ntsis.

Durability: Kimshield deactivation, Thaum ua tau zoo, tsis yog raws li qhov ntev li cas li silanization, txawm hais tias nws tuaj yeem tiv taus ntau cov kuab tshuaj uas tau tshaj nrog borosilicate iav.

Cov ntawv thov: Siv hauv cov chaw kuaj ib puag ncig uas txo kev tawm ntawm adsorption yog qhov tseem ceeb.

Refinive Organosilane Ua Tsev

Mechanism: tus qauv cuam tshuam nrog kev siv cov khoom noj uas ntxim nyiam ntawm cov pab pawg uas khially rau cov pab pawg hydroxyl ntawm cov iav saum npoo. Qhov tshwm sim yog ib nrab ua hydrophobic txheej uas txo reactivity thiab adsorption.

Tus nqi: Feem ntau kim dua li silicone txheej, tab sis muaj cov khoom ruaj khov zoo dua thiab kev tawm tsam adsorption.

Cov ntawv thov: Tsim nyog rau kev cia ntawm cov neeg nkag siab hauv cov chaw kuaj.

Polymer Txheej

Mechanism: Txheej ci xws li polykylhydrhydrogensiloxanes tuaj yeem siv rau cov chaw deactivated. Cov txheej txheej no tuaj yeem ua rau muaj kev cuam tshuam ntawm cov qauv piv txwv thiab cov chaw sib txawv. Polymer txheej cuam tshuam nrog kev thov ib txheej nyias nyias Cov neeg polymers muaj txiaj ntsig zoo li cas nrog cov iav saum npoo los ua ib qho teeb meem zoo ib yam li cov khoom seem uas txwv tsis pub muaj cov khoom sib txawv nyob ntawm cov polymer siv.

Nyob ntawm qhov npaj siab siv, cov txheej txheem polymer tuaj yeem tsim los ua kom tiav cov khoom tshwj xeeb tshwj xeeb, xws li hydrophobicity lossis hydrophilicity lossis hydrophilicity. Los ntawm kev sib cuam tshuam ntawm kev sib cuam tshuam ntawm cov qauv sib xyaw ua ke thiab cov pab pawg sib dhos hauv iav, polymer txheej txheem tuaj yeem txo cov kev tsis txaus siab thiab txhim kho kev sib cais.

Kev ua tau zoo: Cov txheej txheej no tuaj yeem txo cov kev hloov pauv ntawm ib qho chaw nyob tab sis kuj yuav tsis muab cov tib yam tsis tu ncua li Silanization.

Daim ntawv thov: feem ntau siv nyob rau hauv cov capillary rau cov chromatography los txo kev cuam tshuam nrog analytes.

Hauv kev xaus, silanization yog ib qho ntawm cov txheej txheem ua tau zoo tshaj plaws rau txoj kev vim nws txoj kev durability thiab presative nyob rau hauv kev txo cov adaliste adhesion. Thaum cov kev xaiv xws li Kimshadield deactivation thiab reassive organosilane tsev nyob ib puag ncig ntawm tus nqi, kav ntev, thiab haum rau ib daim ntawv thov tshwj xeeb.
