摘要
This paper describes useful information on the capillary electrophoresis-electrospray ionization mass spectroscopy (CE-ESIMS) interfacing for the analysis of amino acids (AAs) in standard mixtures and in child plasma blood serum. The developed procedure allows quantitation of the 20 natural AAs, in a single run, without any derivatization. Limits of detection as low as 3-20 mu mol/l (5-30 pg injected) per analyte were obtained with an efficiency of about 100 000 plates and a peak area relative standard deviation below 4%.
