ABSTRACT
Two high-performance liquid chromatographic methods, with ultraviolet-visible spectrophotometry detection (HPLC-UV/Vis) and with tandem mass spectrometry triple quadrupole interfaced with positive ion mode electrospray ionization detection (HPLC-ESI+-QqQ-MS/MS), for determination and quantification of ten commercial dyes are proposed for control in commercial products. Multiple peaks observed for some of the studied dyes in HPLC-UV/Vis chromatograms forced to obtain structural information by HPLC-ESI-MS/MS method with scan mode. The quality parameters of the two proposed chromatographic methods were evaluated for different requirements of normative, showing detection (LODs) and quantification (LOQs) limits around 60-890 and 200-2990 microg L(-1) for HPLC-UV/Vis, and 4.54-14.3 and 15.0-47.6 microg L(-1) for HPLC-ESI+-QqQ-MS/MS.
