Electrochromatography-electrospray mass spectrometry of textile dyes

Abstract Electrochromatography with its high chromatographic performance has been coupled with electrospray mass spectrometry (MS) for the analysis of non-ionic disperse textile dyes. Electrochromatography offers an alternative to micellar electrokinetic capillary chromatography (MECC) for the analysis of uncharged compounds in conjunction with MS, since MECC generally relies on MS incompatible compounds for micelle formation. Overall, the technique of electrochromatography-MS should find application in many areas.
