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 ...
Characterization of suspected illegal skin whitening cosmetics.
EU market. A newly developed screening method using ultra high performance liquid chromatography-time off flight-mass spectrometry allows routine analysis of suspected products. 163 suspected skin ...
On-line solid-phase extraction with ultra performance liquid chromatography and tandem mass spectrometry for the detection of nicotine, cotinine and trans-3'-hydroxycotinine in urine to strengthen human biomonitoring and smoking cessation studies.
focusing on smoke cessation techniques. In a first approach, a 1:100 dilution of the urine was applied to screen for both passive and active exposure. Intra- and inter-batch reproducibility of this fast ...
Mycotoxin analyses in some home produced eggs in Belgium reveal small contribution to the total daily intake.
(CIT). Intake of DON, ZEA, OTA and CIT via the consumption of home produced eggs seems not to be a matter of concern. Despite this, we recommend to continue in screening other eggs allowing to increase the ...
