Electroosmotic ntws los ntawm kev cuam tshuam ntawm hluav taws xob teb thiab cov txheej txheem ntawm ions ntawm qhov chaw them nqi. Nyob rau hauv capillaries los yog pores, kev tsiv teb tsaws ntawm cov diffuse txheej mus rau qhov oppositely charged electrode ua rau cov kua ntau nyob rau hauv lub channel ntws los ntawm viscous drag.
electroosmotic ntws ua haujlwm li cas?
Electroosmotic ntws tshwm sim thaum ib qho kev tsav tsheb hluav taws xob cuam tshuam nrog cov nqi hluav taws xob hauv hluav taws xob ob txheej ze ntawm cov kua / khoom sib cuam tshuam uas ua rau lub hauv paus hauv lub cev quab yuam uas ua rau cov kua dej ntau ntau.
electroosmotic flow yog dab tsi nws pab tau li cas hauv kev sib cais cov tshuaj hauv capillary electrophoresis?
Electroosmotic Flow
The EOF ua haujlwm zoo tshaj plaws nrog muaj peev xwm zeta loj ntawm cov txheej txheej cation, ib txheej txheej loj ntawm cations rub ntau cov molecules ntawm cathode, Tsis tshua muaj kev tiv thaiv los ntawm ib puag ncig cov tshuaj, thiab tsis muaj pH ntawm 9 kom tag nrho cov SiOH pawg yog ionized.
Yuav ua li cas thiaj txo tau electroosmotic flow?
Electroosmotic ntws tuaj yeem txo tau los ntawm txheej txheej capillary nrog cov khoom siv uas txwv tsis pub ionization ntawm silanol pawg, xws li polyacrylamide lossis methylcellulose.
Yuav ua li cas rau qhov tshwm sim ntawm Electroosmosis?
Qhov no yog vim muaj them hom ntawm cov khoom nto ; los yog nyob rau hauv daim ntawv ntawmnto ionized pawg (piv txwv li SiO- nyob rau hauv cov ntaub ntawv ntawm silica) los yog vim qhov nyiam adsorption ntawm ions los ntawm cov tshuaj. Feem ntau nws yog ob qho tib si ua ke.
