The determination of amino acids is important in numerous fields of research, particularly in
food, biotechnology and wine industries [1, 2]. The analysis of amino acids is commonly
based on liquid chromatography [4, 5] and capillary electrophoresis [6, 7] with pre-or post-
column labeling and spectroscopic detection of the corresponding derivatives. In this work,
Sequential determination of tryptophan and histidine by adsorptive cathodic stripping
voltammetry using standard addition and H-point standard addition method (HPSAM) is ...
