A nonaqueous capillary electrophoresis with laser-induced fluorescence detection method was developed for the quantification of ephedrine and pseudoephedrine after derivatization with 4-chloro-7-nitrobenzo-2-oxa-1, 3-diazol in nonaqueous media. The derivatization was made in off-line mode. By a seri
A differential microdetector with two similar Cu(II) selective membranes was used for discontinuous flow potentiometric determinations of Cu(II). The influence of some factors (temperature, medium, etc.) is eliminated. The method is very simple and sensitive. The results obtained show that the error
