A fast HPLC method using a monolithic silica column was developed for the measurement of amino acids. The amino acids were pre-column derivatized with 4-fluoro-7-nitro-2,1,3-benzoxadiazole (NBD-F) and separated on a monolithic silica column (MonoClad C18-HS, 250 mm × 3 mm

The continuous nature of micro free-flow electrophoresis (mu-FFE) was used to monitor the effect of a gradient of buffer conditions on the separation. This unique application has great potential for fast optimization of separation conditions and estimation of equilibrium constants.

An in-capillary derivatization of amino acids and peptides with 4-fluoro-7-nitro-2,1,3-benzoxadiazole (NBD-F) was developed for their subsequent capillary electrophoretic analysis with laser-induced fluorescence detection (lambda (ex)=488 nm). The in-capillary derivatization was achieved in zone-passing mode by introducing successive plugs of sample

4-Fluoro-7-nitro-2,1,3-benzoxadiazole (NBD-F) has been characterized as a fluorogenic labeling reagent for high speed, online microdialysis-capillary electrophoresis (MD-CE) assays for amino acid neurotransmitters. NBD-F labeled amines are efficiently excited using 488 nm light allowing more common lasers to be used for
