Detection of whitening agents in illegal cosmetics using attenuated total reflectance-infrared spectroscopy.
attenuated total reflectance-infrared (ATR- IR) spectroscopy, combined with chemometrics, was evaluated for that purpose. It was found that the combination of ATR- IR with the simple chemometric technique ...
Is the different time trend (1997-2008) of the obesity prevalence among adults in the three Belgian regions associated with lifestyle changes?
the Flemish and Brussels Regions, but remained stable in the Walloon Region, the latter still showing the highest prevalence. The purpose of the present study is to explore if the different time trends ...
Multi-dye residue analysis of triarylmethane, xanthene, phenothiazine and phenoxazine dyes in fish tissues by ultra-performance liquid chromatography-tandem mass spectrometry.
background levels of the xanthene dyes, the two rhodamine dyes could only be determined above 0.75ngg(-1). For these dyes, the method can only be used for screening purposes. To show the applicability of the ...
