Difference between icpms and aas
WebSep 29, 2024 · The ICP uses an MS (mass spectrometric detector) while AAS uses a UV-Visible spectrophotometer as a detector. The ICP (plasma) has a higher flame temperature so ALL the atoms are in emission while the AAS has a much cooler flame and thus atoms can either emit or absorb radiation. Which is better, ICP OES or ICP-MS? WebApr 29, 2024 · The key difference between ICP-AES and ICP-MS is that ICP-AES provides a higher detection limit down to ppm or ppb, whereas ICP-MS provides a lower detection …
