Development of novel analytical methods to trace small micro- and nanoplastics in food matrices
identified by Raman microspectroscopy. As a side supporting technique, atomic force microscopy (AFM) and transmission electron microscopy (TEM) have been employed to investigate the size, shape and the ...
Particle size analysis of pristine food-grade titanium dioxide and E 171 in confectionery products: Interlaboratory testing of a SP-ICP-MS screening method and confirmation with transmission electron microscopy.
electron microscopy (TEM) was used as a confirmatory technique and served as the basis for bias estimation. The optimisation of the sample preparation step showed that when this protocol was applied to the ...
Physicochemical Characterization of the Pristine E171 Food Additive by Standardized and Validated Methods.
standardized and validated methodologies to characterize representative samples of 15 pristine E171 materials based on transmission electron microscopy (TEM) and single-particle inductively coupled plasma mass ...

Physical Characterization of Nanomaterials in Dispersion by Transmission Electron Microscopy in a Regulatory Framework
8, Number 270, Cham, p.21 (2015) ISBN: 978-3-319-15176-2 Abstract: TEM is one of the few techniques that can identify nanoparticles according to the current definitions. This chapter focuses on the ...
Characterization of the TiO2 E171 food additive
descriptive TEM and using a combination of TEM imaging and image analysis. The latter approach allows to assess the distribution of the particle properties (size, shape, surface structure) quantitatively. For ...
