Determination of effective mobilities of EOF markers in BGE containing sulfated ?-cyclodextrin by a two-detector method
Original language description
A neutral marker of the EOF can gain a nonzero effective mobility because of its possible interaction with a charged complexing agent, such as a chiral selector in CE. We determined effective mobilities of four compounds often used as EOF markers (dimethyl sulfoxide,mesityl oxide, nitromethane, and thiourea) in the BGE-containing sulfated -CD (60 g/L). All the compounds studied were measurably mobilized by their interaction with the selector. The highest effectivemobility (-3.0.10MINUS SIGN 9m2sMINUS SIGN 1VMINUS SIGN 1) was observed for thiourea and the lowest (-1.5.10MINUS SIGN 9m2sMINUS SIGN 1VMINUS SIGN 1) for dimethyl sulfoxide and nitromethane. The mobilities were determined by a new two-detector pressure mobilization method (2d method), which wepropose, and the results were confirmed by standard CE measurements. In the 2d method, one marker zone is situated in the BGE containing the charged selector, while the second marker zone is surrounded with a selector-free BGE, which pre
