“…Measurements based on 49 Ti have been found to be sensitive enough when assessing Ti in complex samples. [35][36][37][38][39] A tuning solution containing Be, Ce, Fe, In, Li, Mg, Pb, and U (1.0 mg L −1 ) and Ag or Ti (10 mg L −1 ) was used to adjust the ICP-MS prior to analysis. The ow rate was daily determined by weighing the amount of deionized ultrapure water aspirated by the sample introduction system for 1.0 min (measurements in triplicate).…”

Speciation analysis plays a key role in understanding the biological activity and toxicity of an element. So far, classical speciation analysis focused only on the dissolved fraction of an elemental species, whereas nanoparticle forms of analytes are being widely found in consumer and industrial products. A significant contributor to human exposure to nanoparticles is through food into which nanoparticles can be incorporated from endogenous sources or they may be formed naturally in the living organisms. Nanoparticles often undergo changes in the food matrices and upon consumption, in the gastrointestinal tract, which present a significant challenge to their characterisation. Therefore, a combination of both classical and nanoparticle speciation analytical techniques is needed for the characterisation of both dissolved and particulate forms of the chemical species. This article presents and discusses the current trends in analysis of nanoparticle behaviour in the gastrointestinal tract and formation and characterisation of biogenic nanoparticles.
