ʻO ka hoʻohana ʻana i ka capillary silica fused ma CE i kekahi manawa hiki ke maʻalahi ma muli o nā hopena makemake ʻole me ka adsorption o ka laʻana a i ʻole ke kūpaʻa ʻole o ka EOF.Hiki ke pale pinepine ʻia kēia ma ka uhi ʻana i ka ʻili o loko o ka capillary.Ma kēia hana, hōʻike mākou a hōʻike i ʻelua mau ʻāpana polyelectrolyte hou (PECs) poly(2-(methacryloyloxy)ethyl trimethylammonium iodide) (PMOTAI) a me ka poly(3-methyl-1-(4-vinylbenzyl)-imidazolium chloride) (PIL- 1) no CE.Ua aʻo ʻia nā capillaries i uhi ʻia me ka hoʻohana ʻana i ke ʻano o nā paʻi wai o ka pH like ʻole, ka ikaika ionic, a me ka haku mele.Hōʻike kā mākou mau hopena e hiki ke hoʻohana ʻia nā polyelectrolytes i noiʻi ʻia ma ke ʻano he semi-permanent (physical adsorbed) me ka liʻiliʻi o ʻelima mau holo paʻa ma mua o ka pono o ka hoʻōla hou ʻana o ka uhi pōkole.Ua hōʻike ʻia nā PEC ʻelua i ka hoʻohaʻahaʻa nui ʻana i ka pH 11.0.Ua ʻoi aku ka kiʻekiʻe o ka EOF me ka hoʻohana ʻana i nā pale o Good ma mua o ka hoʻopaʻa sodium phosphate ma ka pH like a me ka ikaika ionic.ʻO ka mānoanoa o nā papa PEC i aʻo ʻia e ka quartz cry stal microbalance he 0.83 a me 0.52 nm no PMOTAI a me PIL-1.Hoʻoholo ʻia ka hydrophobicity o nā papa PEC ma o ka nānā ʻana i kahi moʻo homologous o alkyl benzoates a hōʻike ʻia ma ke ʻano he mau mahele.Hōʻike kā mākou hopena i ka hydrophobicity like nā PEC ʻelua, i hiki ai ke hoʻokaʻawale i nā pūhui me ka log Po/w > 2. Ua hōʻike ʻia ka hiki ke hoʻokaʻawale i nā lāʻau cationic me nā β-blockers, nā pūhui i hoʻohana hewa ʻia i ka doping.Ua hiki no hoi i na lole elua ke hookaawale i na hua hydrolysis o ka wai ionic 1,5-diazabicyclo [4.3.0] non-5-ene acetate ma na kulana acidic loa, kahi i hiki ole ai i na capillaries fused fused i ka hookaawale ana.
