Improvement of derivatized amino acid detection sensitivity in micellar electrokinetic capillary chromatography by means of acid-induced pH-mediated stacking technique
Derivatization is a frequently used sample preparation procedure applicable to the enhancement of analyte detection sensitivity. Amino acids mostly require derivatization prior to electrophoretic or chromatographic analysis, especially if spectrophotometric detection is used. This study presents an on-line preconcentration technique for derivatized amino acids. The sensitivity of the method was...
متن کاملChiral analysis of biogenic DL-amino acids derivatized by urethane - protected alpha-amino acid N-carboxyanhydride using capillary zone electrophoresis and micellar electrokinetic chromatography.
A new analytical method for enantioselective separation of DL-amino acids derivatized by N-fluorenylmethoxycarbonyl-L-alanyl N-carboxyanhydride (FMOC-L-Ala-NCA) using capillary electrophoresis was developed. Separation parameters, such as composition and pH of the background electrolyte, and concentration of gamma-cyclodextrin (in capillary zone electrophoresis) and sodium dodecyl sulfate (in m...
متن کاملAnalysis of prostaglandins by micellar electrokinetic capillary chromatography.
This paper presents a rapid and reliable micellar electrokinetic capillary chromatography (MEKC) method to separate major prostaglandins and thromboxane B2. The running buffer was modified with sodium dodecyl sulfate (SDS). The effects of the SDS concentration on the migration behavior of analytes was also examined. Moreover, the influences of electrolyte concentration and capillary temperature...
متن کاملQuantitation of chiral amino acids from microalgae by micellar electrokinetic chromatography and laser induced fluorescence detection
Running Title: Chiral analysis of microalgae amino acids by MEKC-LIF ABSTRACT In this work, a chiral and a non-chiral micellar electrokinetic chromatography with laser-induced fluorescence detection (MEKC-LIF) have been combined to identify and quantify a group of D-and L-amino acids (D/L-aa) in different microalgae samples. The combination of the non-chiral and chiral-MEKC-LIF methods made eas...
متن کاملPrinciples of micellar electrokinetic capillary chromatography applied in pharmaceutical analysis.
Since its introduction capillary electrophoresis has shown great potential in areas where electrophoretic techniques have rarely been used before, including here the analysis of pharmaceutical substances. The large majority of pharmaceutical substances are neutral from electrophoretic point of view, consequently separations by the classic capillary zone electrophoresis; where separation is base...
