reached a maximum concentration of 3.8 ± 0.9 ng ml−1 within 35.0 ± 10.2 min and was slowly eliminated from the plasma, with a half-life time (T1 /2) of 931.1 ± 30.8 min. Meanwhile, AFM1 reached a plateau ...
Study of the possible migration risks of food contact materials for children under 3 years
duration tests such as microwave, sterilisation and dishwasher treatment on the profile of the different migrants was determined and compared with a reference treatment (30 min at 40°C) and the standard EU ...
Multi-dye residue analysis of triarylmethane, xanthene, phenothiazine and phenoxazine dyes in fish tissues by ultra-performance liquid chromatography-tandem mass spectrometry.
separated within only 12min on a C18 BEH column using 1mM ammonium acetate in water at pH 4.5 and acetonitrile as mobile phases at a flowrate of 0.4mLmin(-1). The presented method was validated as defined by ...
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.
method (10min) was assessed for three concentration levels and were found to be less than 8% for each analyte while the accuracy was between 89 and 113%. To further improve the sensitivity of this approach ...

2 min) and can easily be performed (no laborious clean-up). The presented method is environmental friendly with significant reduction in solvent consumption. Health Topics: Food consumption and food ...
Rapid method for the confirmatory analysis of chrysoidine in aquaculture products by ultra-performance liquid chromatography-tandem mass spectrometry.
water and an acetonitrile gradient within 6 min. Mass spectrometric analysis was performed in the positive electrospray MS / MS mode. The limit of quantification was 0.25 ng/g, which was 30 times lower ...
Optimization of the blanching process to reduce acrylamide in fried potatoes
temperature was the main influencing factor for sugar extraction and subsequent acrylamide mitigation. Blanching at temperatures of about 70 °C for a short period of time (about 10 min) was more efficient ...
