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 ...

TEM and SP-ICP-MS analysis of the release of silver nanoparticles from decoration of pastry.

particles was studied by electron diffraction and chemical information was obtained by combining HAADF- STEM imaging with EDX spectroscopy and mapping. The TEM results were confirmed by SP- ICP- MS. The ...

The European COPHES/DEMOCOPHES project: towards transnational comparability and reliability of human biomonitoring results.

shortcomings in the determination of Cd when using certain ICP / MS methods. Results were corrected by reanalyzes. The COPHES / DEMOCOPHES project for the first time succeeded in performing a harmonized ...
