Tšebeliso ea li-silica capillary tse se nang letho ho CE ka linako tse ling e ka ba tšitiso ka lebaka la litlamorao tse sa rateheng tse kenyelletsang adsorption ea sampole kapa ho se tsitse ha EOF.Hangata sena se ka qojoa ka ho roala bokaholimo bo ka hare ba capillary.Mosebetsing ona, re hlahisa le ho khetholla mefuta e 'meli ea polyelectrolyte coatings (PECs) poly(2-(methacryloyloxy)ethyl trimethylammonium iodide) (PMOTAI) le poly(3-methyl-1-(4-vinylbenzyl) -imidazolium chloride) (PIL- 1) bakeng sa CE.Li-capillaries tse koahetsoeng li ile tsa ithutoa ho sebelisoa letoto la li-buffers tse nang le metsi tse fapaneng tsa pH, matla a ionic, le sebopeho.Liphetho tsa rona li bonts'a hore li-polyelectrolyte tse batlisisitsoeng li ka sebelisoa e le liaparo tse sa feleng (tse adsorbed) tse nang le bonyane li-runs tse hlano tse tsitsitseng pele ho tsosolosoa ha nako e khutšoanyane ho hlokahala.Li-PEC ka bobeli li bontšitse botsitso bo theohileng haholo ho pH 11.0.EOF e ne e phahame ho sebelisoa li-buffers tsa Good ho feta ka sodium phosphate buffer ka pH e tšoanang le matla a ionic.Botenya ba likarolo tsa PEC tse ithutoang ke quartz cry stal microbalance e ne e le 0.83 le 0.52 nm bakeng sa PMOTAI le PIL-1, ka ho latellana.Hydrophobicity ea likarolo tsa PEC e ile ea khethoa ka tlhahlobo ea letoto la li-alkyl benzoate tse ts'oanang 'me tsa hlahisoa e le likarolo tsa ho aba.Sephetho sa rona se bontša hore li-PEC ka bobeli li ne li e-na le hydrophobicity e tšoanang, e ileng ea nolofalletsa ho arohana ha metsoako ka log Po / w > 2.
