Electroosmotic flow 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 muaj lub zog hauv lub cev uas ua rau cov kua dej ntau ntau.
electroosmotic flow yog vim li cas nws tshwm sim?
Electroosmotic flow tshwm sim vim cov phab ntsa ntawm cov hlab capillary yog hluav taws xob them . Qhov saum npoo ntawm silica capillary muaj ntau ntawm silanol pawg (–SiOH). Ntawm pH qib siab tshaj li ntawm 2 lossis 3, cov pab pawg silanol ionize los tsim cov pa phem silanate ions (–SiO–).
electroosmotic flow generated li cas?
Electroosmotic ntws yog tshwm sim by Coulomb quab yuam induced los ntawm ib tug hluav taws xob teb ntawm net mobile electric charge nyob rau hauv ib tug daws. … Qhov tshwm sim yog hu ua electroosmotic flow.
Dab tsi cuam tshuam rau electroosmotic flow?
Micellar Electrokinetic Capillary Chromatography (MEKC)
Cov khoom sib xyaw muaj cov polar tsis zoo them qhov chaw thiab yog ib txwm nyiam rau qhov zoo them anode. … Cov yam ntxwv uas cuam tshuam rau cov electroosmotic ntws hauv MEKC yog: pH, surfactant concentration, additives, thiab polymer coatings ntawm phab ntsa capillary.
Vim li cas electroosmotic flow pH nyob ntawm?
Lub electro-osmotic flow (EOF) tuaj yeem piav qhia raws li kev tshaj tawm lossis kev txav mus los. … Vim tias tus nqi ntawm cov hlab ntsha sib txawv raws li kev ua haujlwm ntawm pH, zetamuaj peev xwm kuj txawv nrog pH, txhais tau hais tias kev txav mus los thiab kev tshaj tawm ntawm EOF yog pH siab heev.
