Determination of malachite green, crystal violet, brilliant green and methylene blue by micro-cloud-point extraction and nonlinear laser wave-mixing detection interfaced to micellar capillary electrophoresis

A laser wave-mixing CE detection method is reported for separation and detection of malachite green (MG), crystal violet (CV), brilliant green (BG), methylene blue (MB), and the leuco-metabolites of MG and CV residues in aquacultures.
