Umngcele we-ITP olinganiselayo we-EOF usetshenziselwe ukunqwabelanisa ama-anion asuka kumasampuli e-conductivity ephezulu phakathi nomjovo we-electrokinetic oqhubekayo wesampula.Ku-polystyrenesulfonate/poly(diallyldimethylammonium chloride) i-polyelectrolyte coated capillary, isikhathi lapho umngcele we-ITP uphuma khona ku-capillary singanwetshwa ngokulinganisa ukunyakaza komngcele ne-EOF.Kusetshenziswa i-bis-tris-propane electrolyte, umngcele we-ITP wasuswa ku-capillary ngaphakathi kwe-7min, ngenkathi usebenzisa i-triethanolamine umngcele we-ITP wawuseku-30% we-capillary ngemva kwe-2h yomjovo.Kusetshenziswa lezi zinhlelo, ukuzwela kwengxubevange yama-asidi emvelo alula ku-100mM Cl(-) kwathuthukiswa ngo-700-800-fold kusetshenziswa i-bis-tris-propane ngomjovo we-capillary wesampula kanye nemizuzu emi-5 yomjovo we-electrokinetic ku-+28kV. , kanye ne-1100-1300-fold usebenzisa i-triethanolamine kanye ne-60min yomjovo we-electrokinetic ngaphansi kwezimo ezifanayo.Amandla endlela okufanele asetshenziswe kumasampula e-conductivity ephezulu aboniswa ngokupakisha i-capillary yonke egcwele umchamo ene-naphthalenedisulfonic acid, enemikhawulo yokutholwa engaphansi izikhathi ezingama-450 kunaleyo engafinyeleleka ngomjovo ojwayelekile we-hydrodynamic.
