✦ Synopsis

The effects of cyclodextrin (CD) as mobile phase additive on the fluorescence intensity of dansylamino acids were investigated in microcolumn liquid chromatography. Signal enhancement was observed for /3-and y-CD, whereas no signal enhancement was observed for a-CD. The signal enhancement was pronounced for neutral dansylamino acids, and larger fluorescence enhancement was observed for mobile phases containing higher concentrations of CD.
