Across
  1. 2. part of the ICP-MS where three concentric tubes allow the flow of argon for various purposes
  2. 3. atoms of the same element with the same number of protons (and electrons) but different numbers of neutrons, resulting in a different mass number
  3. 5. are used the source of X-rays for SEM-EDS
  4. 7. method used for surface elemental analysis
  5. 8. 4th state of matter, ionized gas
  6. 9. method used for elemental analysis that uses a laser beam to create a microplasma and excite species that can later emit at characteristic wavelengths
Down
  1. 1. type of interference in ICP-MS occurs when molecules formed from the plasma, sample, and matrix gases (like argon, oxygen, nitrogen, carbon, etc.) have the same mass-to-charge ratio (\(m/z\)) as the analyte
  2. 4. 2 words, no spaces,the region within a sample where incident X-rays penetrate, causing atoms to fluoresce
  3. 6. atoms of different elements that have the same mass number but different numbers of protons and neutrons
