Outline of Final Research Achievements

To accelerate vaporization, atomization, and ionization efficiencies in laser ablation inductively coupled plasma mass spectrometry, we merged HCl gas with laser-ablated particles before introduction into the plasma, to convert their surface constituents from oxides to lower-melting chlorides. When particles were merged with HCl gas generated from HCl solution at 200℃, the measured concentrations of elements in the particles were 132% higher on average than the concentrations in particles merged with ultrapure water. Particle corrosion and oxide conversion to chlorides were confirmed by scanning electron microscopy and X-ray photoelectron spectroscopy, respectively. This experimental results suggests that vaporization, atomization, and ionization of the ablated particles in the ICP improved when HCl gas was merged with the ablated particles.
