Publication Type: Peer reviewed scientific article Authors: Philippe Szternfeld; Jessica Marchi; Svetlana V. Malysheva; Laure Joly Source: Food Analytical Methods, Volume 12, Issue 10 (2019) ...
Commutability of food microbiology proficiency testing samples.
demonstrated. In the clinical field, the use of noncommutable PT samples has led to erroneous evaluation of the performances when different analytical methods were used. This study aimed to provide a first ...

Chromatography in the detection and characterization of illegal pharmaceutical preparations.
for analytical laboratories to detect and characterize them. Spectroscopic techniques such as infrared spectroscopy and Raman spectroscopy have always been the first methods of choice to detect ...
Using multiple measures of inequalities to study the time trends in social inequalities in smoking.
inequalities simultaneously. Also the analytical approach used often did not account, as recommended, for the changes in the relative distribution of social groups and the changes in the absolute level of the ...
Accuracy profiles assessing the validity for routine use of high-performance thin-layer chromatographic assays for drug formulations
limits set at +/-5%. This means that the two analytical thin-layer chromatographic methods are capable of making accurate results at the studied concentration ranges of each compound. Measurement ...
Development and validation of qualitative SYBR®Green real-time PCR for detection and discrimination of Listeria spp. and Listeria monocytogenes.
and the “Definition of minimum performance requirements for analytical methods of GMO testing”. The developed assays target the iap, prs and hlyA genes that belong to or neighbour the virulence cluster ...
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 ...
Scientific opinion on the presence of dioxins (PCDD/Fs) and dioxin-like PCBs (DL-PCBs) in commercially available foods for infants and young children
children where only a few results are available so far. Moreover, thesensitivity of the analytical methods should be improved, if lower ML s were to be considered in the future.presence of dioxins and ...
