Non-aqueous capillary electrophoretic separation and detection of 6H-pyrimido[2,1-a]isoindoles

A non-aqueous capillary electrophoresis system for separating and detecting antidepressant drugs based on the coupling of capillary electrophoresis separation in acetonitrile and UV detection is described. The system offers a rapid simultaneous measurement in less than 12 min for six priority pyrimidoisoindoles. These antidepressants were detected down to the 2.5 x 10(-6)-4.2 x 10(-6) mol/L …

Determination of amino derivatives of polycyclic aromatic hydrocarbons using capillary electrophoresis

A simple and sensitive capillary electrophoretic method was developed for the separation and determination of selected carcinogenic amino derivatives of polycyclic aromatic hydrocarbons. The influence of pH and content of methanol in the background electrolyte on electrophoretic mobilities of 2-aminofluorene, 2,7-diaminofluorene, I-aminonaphthalene, I-aminopyrene and 6-aminochrysene was studied. The detection limits were estimated to be 2.5 …
