Determination of selenomethionine by high-performance liquid chromatography-fluorescence detection coupled with on-line oxidation.

Chiaki Aoyama et al.

Analytical sciences : the international journal of the Japan Society for Analytical Chemistry, 25(1), 63-65 (2009-01-14)

A simple and sensitive determination method for selenomethionine (Se-Met) using an HPLC-fluorescence detection system coupled with an on-line electrochemical reactor has been developed. NBD-F (4-fluoro-7-nitro-2,1,3-benzoxadiazole) was used as the fluorescent derivatization reagent for Se-Met. NBD-Se-Met was separated from NBD-derivatives of

A highly sensitive HPLC method with automated on-line sample pre-treatment and fluorescence detection for determination of reboxetine in human plasma.

Nasr Y Khalil

Talanta, 80(3), 1251-1256 (2009-12-17)

A fully automated, rapid and highly sensitive HPLC method with automated sample pre-treatment by column-switching system and fluorescence detection has been developed for the trace quantitative determination of the new antidepressant reboxetine (RBX) in human plasma. A simple pre-column derivatization

Selective preconcentration of amino acids and peptides using single drop microextraction in-line coupled with capillary electrophoresis.

Yang-Ki Park et al.

Journal of chromatography. A, 1217(20), 3357-3361 (2010-04-13)

Single drop microextraction (SDME) can be in-line coupled with capillary electrophoresis by attaching a drop to the tip of a capillary. With a 2-layer drop comprised of an aqueous basic acceptor phase covered with a thin organic layer, acidic analytes
