Optimization and validation of an analytical method for the quantification of short- and medium-chained chlorinated paraffins in food by gas chromatography-mass spectrometry
quantification of short- and medium-chained chlorinated paraffins (SCCP s and MCCP s, respectively) in a range of food matrices using gas chromatography-electron capture negative ionization-mass spectrometry (GC- ...
Physico-chemical characterisation of the fraction of silver (nano)particles in pristine food additive E174 and in E174-containing confectionery.
products by transmission electron microscopy (TEM) and single-particle inductively coupled plasma-mass spectrometry (spICP- MS). TEM analysis showed that all samples contained micrometre-sized flakes and ...
