Mass Spectrometry News and Research

RSS

Mass spectrometry is an analytical method used to identify different compounds based on the atomic sample constitution of the molecules and their charge state, which enables “blind” analysis of an unknown sample without any prior knowledge of its composition.

Plastic additives found in 85% of foods raise concern for infant health

Researchers assessed plasticizer levels in foods typical of the Spanish diet and found widespread contamination, with infants showing the highest exposure. Certain additives, like DEHP, exceeded safety thresholds in high-exposure scenarios.
