Modular Method for the Determination of Polycyclic Aromatic Hydrocarbons in Spices and Dried Herbs by Gas Chromatography–Tandem Mass Spectrometry
removemaximum of co-extracts and to obtain clean samples. This method has a limit of quantification of 0.5 μgkg−1for each PAH andthe validation criteria fully satisfied the Commission Regulation (EU) No. 836/2011 ...
Development of a dot-blot assay for the detection of mould-specific IgE in the Belgian population
dot-blot assay was validated against the CAP test. Sensitization rate to ten common indoor and outdoor mould species in 344 serum samples was calculated. For each serum with more than one reactivity, the ...
