Abstract: Separation and determination of amino acids were carried out by means of a glycerolpropyl-diethylenesilyl bonded phase (GDSB) combined with a UV-detector at 254nm. An acetate buffer solution (pH 5.75) containing 2.5?10-4 mol/L of copper ion and 2.5?10-4 mol/L of hexyl sulfonate was used as a mobile phase. The effects of the mobile phase composition on capacity factor and detection sensitivity were examined. The results the suifability of GDSB system as a stationary phase for analysis of amino acids showed by HPLC.
