Estimation of the Uncertainties Related to the Measurement of the Size and Quantities of Individual Silver Nanoparticles in Confectionery.

Keywords: Single particle ICP-MS Abstract: E174 (silver) is a food additive that may contain silver nanoparticles (AgNP). Validated methods are needed to size and quantify these particles in a regulatory ...

A systematic evaluation of Flow Field Flow Fractionation and single-particle ICP-MS to obtain the size distribution of organo-mineral iron oxyhydroxide colloids.

study was set up to determine the size of environmentally relevant FeOx colloids with new methods, i.e. Flow Field Flow Fractionation (FlFFF- UV- ICP- MS) and single-particle ICP- MS / MS (sp- ICP- MS) ...

Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography-tandem mass spectrometry

liquid chromatography – tandem mass spectrometry (UHPLC- MS / MS) method for the simultaneous determination of four parabens (methyl-, ethyl-, propyl-, and butyl-paraben (MeP, EtP, PrP, BuP), four ...

Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials.

approach on the certified reference materials ERM- FD100 and ERM- FD304. The image analysis method was validated in an inter-laboratory study by 19 laboratories, which resulted in a within-laboratory ...
