• X-ray diffraction measurements, Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy clarified that an amorphous phase and Li2CO3 were produced on the Li4SiO4 surface after the CO2 reaction in the presence of water vapor. (academic-accelerator.com)
  • However, compared with other types of mass spectrometry, such as thermal ionization mass spectrometry (TIMS) and glow discharge mass spectrometry (GD-MS), ICP-MS introduces many interfering species: argon from the plasma, component gases of air that leak through the cone orifices, and contamination from glassware and the cones.
