The investigation of the stabilities of o-phthalaldehyde/2-mercaptoethanol derivatives of amino acids using a precolumn reaction technique and a high-pressure liquid chromatographic procedure is reported. The amino acid derivatives are shown to be stable on the high-pressure liquid chromatography co
A reversed-phase high-performance liquid chromatographic method for the detection of boronophenylalanine is described. Determination was obtained by precolumn reaction of o-phthalaldehyde with a mixture of standard amino acids containing boronophenylalanine and separating the corresponding o-phthala
An analytical method for a rapid reverse-phase liquid chromatography of amino acids is presented. The total analysis time was 19 min. The average relative deviation over the measured peak area was lower than 10% and the fluorescent response was linear with concentration for OPA derivatives (r > 0.99
