Coupling electrophoretic separation with inductively coupled plasma spectroscopic detection: interfaces and applications from elemental speciation, metal–ligand interaction to indirect determination

Electrophoresis in capillaries/microchannels interfaced with inductively coupled plasma spectrometries shows great potential in elemental speciation and interaction with ligands, and indirect determination by taking advantage of both separation and detection.

Visualization of As(III) and As(V) distributions in degraded paint micro-samples from Baroque- and Rococo-era paintings

Orpiment and realgar are two artists' pigments that appear not to be stable upon light exposure, quickly degrading to arsenic trioxide and arsenate. Their identification appears challenging but can be overcome by the use of synchrotron based techniques such as μ-XANES.
