Rapid determination of amino acids in biological samples using a monolithic silica column.

Yanting Song et al.

Amino acids, 42(5), 1897-1902 (2011-04-21)

A high-performance liquid chromatography method in which fluorescence detection is used for the simultaneous determination of 21 amino acids is proposed. Amino acids were derivatized with 4-fluoro-7-nitro-2,1,3-benzoxadiazole (NBD-F) and then separated on a monolithic silica column (MonoClad C18-HS, 150 mm×3

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

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
