A pre-column fluorescence derivatization method is described for the highperformance liquid chromatographic determination of N-terminal tyrosine-containing oligopeptides involving methionine-enkephalin and leucine-enkephalin. The peptides are converted into fluorescent derivatives by heating in a we

This article describes a new method for the determination of ultra trace levels of 12 N-methylcarbamates in drinking water via micellar electrokinetic Ε½ . chromatography MEKC . Two steps were employed to enhance the detection sensitivity. The sample was first preconcentrated by C bonded SPE cartridg
