A capillary electrophoretic method for determinating main components in isomaltooligosaccharide formulation was describled The influences of various separartion conditions including buffer conceration,pH,voltage and detection wavelength were investigated By using an uncoated silica capillary (75?μm i d ,60cm of total length,and 50?cm of efficient length) and 75?mmol/L borax (pH10 5) as carrier electrolyte,the sugar derivatized with α naphymethami...
