[Analysis Case] Analysis of fluorescent dyes contained in laundry detergents
Qualitative analysis by simultaneous measurement of fluorescence and mass.
Fluorescent dyes are used in commercial clothing, detergents, paints, etc., due to their effect of increasing apparent whiteness by absorbing ultraviolet light and emitting visible light (fluorescence). In this case study, we attempted to qualitatively analyze the fluorescent whitening agents contained in laundry detergents by connecting a fluorescence detector (FL) and a mass spectrometer (MS) to the liquid chromatography (LC). As a result, we were able to identify peaks that emit fluorescence from the numerous peaks detected by MS, and further estimation of the components was possible through the analysis of the MS spectra. By connecting FL and MS, it is possible to determine the presence of fluorescent components and estimate the components in a single measurement.
