Separation of dithiocarbamate metal complexes by micellar electrokinetic chromatography
Separation of a number of transition metal complexes with bis(2-hydroxyethyl)dithiocarbamate (HEDTC) by micellar electrokinetic capillary chromatography (MEKC) with direct photometric detection was investigated. Pre-capillary complexation was shown to be superior to on-capillary complexation in terms of the number of metals ions which could be detected and their peak shapes, enabling analysis o...
متن کاملSeparation of Metal Bis(2-hydroxyethyl)dithiocarbamate Complexes by Micellar Electrokinetic Capillary Chromatography
A method was developed for the separation of CdII, PbII, PtII, CoII, NiII, BiIII, CrII, CuII and HgII bis(2-hydroxyethyl)dithiocarbamate (HEDTC) complexes by micellar electrokinetic capillary chromatography. The complexes were formed by pre-capillary reaction of the metal ions with an excess of the ligand and then separated using a 100 mm borate buffer (pH 9.2) containing 4% methanol (v/v), 10 ...
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 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...
