“…Trapping of the hydrides onto the drop does not rely on their partitioning among the gas phase and the solvent phase, as typically developed for organic compounds, but on their catalytic decomposition onto the Pd(0) formed in the drop as a result of the hydrogen evolved during the derivatisation reaction. A faster mass transfer was observed for the methyl mercury hydride from the headspace to the drop in comparison with SPME, which allowed equilibrium to be reached in a significantly shorter time [19].…”
