(7) Interference elimination
1.
Mass spectrum type including interference isobaric interference, polyatomic ions, and an electric double oxides interference
Table 5-42 Common interference correction equations in ICP-MS determination
Polyatomic ion interference is the most important source of interference in ICP-MS, which can be eliminated by interference correction equations, instrument optimization, and collision reaction cell technology
Table 5-43 Commonly interfered polyatomic ions in ICP-MS determination
2.
Non-mass spectrometric interference mainly includes matrix suppression interference, space charge effect interference, physical effect interference and so on
