A new, rapid and sensitive microextraction technique named vortex-assisted liquid–liquid–liquid microextraction (VALLLME) is proposed. The complete extraction process involves two steps. First, a vortex-assisted liquid–liquid microextraction (VALLME) procedure was used to extract the analytes from a relatively large volume of sample (donor phase) to a small volume of organic solvent (intermediate...
A fast and simple HPLC-based assay has been developed for the simultaneous determination of homocysteine (Hcy) and methionine (Met) in plasma and urine samples, utilizing as small volume of sample as 10μL. The assay uses on-column derivatization with o-phthaldialdehyde. The separation of Hcy and Met was achieved in 14min on a reversed phase C-18 column, followed by fluorescence detection (excitation...
