Physicochemical characterisation of several types of the E171 food additive

particle inductively coupled plasma mass spectroscopy (sp- ICP- MS) following CEN / TC 352 guidelines. The E171 samples were purchased on the Belgian market or were obtained from European producers. In ...

Validation of single particle ICP-MS for routine sizing and quantification of the fraction of silver nanoparticles in E174 food addititves and confectionery products

for validated methods to size and quantify these particles. Single particle inductively coupled plasma-mass spectrometry (spICP- MS) is thereby a promising technique as it is capable of sizing and ...

Combining TEM with single particle ICP-MS: assessing the size of individual nanoparticles in food additives by multiple techniques

of nano-sized particles in food, Sciensano, Issue Sciensano, Brussels, Belgium (2019) Keywords: Single particle ICP-MS transmission electron microscopy Health Topics:  Trace elements Nanomaterials ...

Screening for nanoparticles in complex matrices within a regulatory framework: are we there yet?

particle inductively coupled plasma – mass spectrometry (spICP- MS) was studied as a screening tool to determine the number-based size distribution of Ag particles, their particle number and mass ...

Arsenic Speciation Analysis Elucidates the Risk Assesment of Food Supplements with Ingredients of Marine Origin. 9th Nordic Conference on plasma spectrochemistry

toxicity, such as arsenosugars and arsenolipids which can occur in marine matrices, in particular in algae. Analysis of As i in algae by HPLC- ICP- MS is complicated by the presence of arsenosugars in these ...

Human absorption of silver ENM: through particles or ions?

collected. After 24 hours, selected tissues were sampled and total Ag concentrations were measured by ICP- MS. After treatment by IV injection with the silver salt, largest Ag concentrations were found in the ...

Determination of total Ti in candy

concentration can be determined after chemical digestion but dissolving Ti needs the use of concentrated sulfuric acid or hydrofluoric acid (HF). The use of S is not optimal for ICP- MS analysis, because several ...

Mercury and cadmium levels in Belgian children and their mothers

levels were measured in centrifuged and acidified urine by ICP- MS (LOQ =0.01µg/g), while total mercury was analyzed by FIMS on hydrolyzed hairs (LOQ =0.08µg/g). Results The geometric mean level for ...
