Plasma - ion sources - a mass spectrometer for trace elements

摘要

a plasma mass spectrometer ion sources for trace elements, which is equipped with a plasma erzeugungsabschnitt, a beam - erzeugungsabschnitt, a beam - fokussierabschnitt, a ionenmassen - analysiererabschnitt and an ion detektorabschnitt is revealedit also has a resonance ladungsaustausch - reaktionsabschnitt and ion power - analysiererabschnitt, although the two sections between the ion - fokussierabschnitt and ionenmassen - analysiererabschnitt are arranged and which are constructed such that the einfal loins ion contained fastinterfering ions in the resonance ladungsaustausch - reaktionsabschnitt in fast neutral atoms (or molecules) and slow, disturbing ions converted, and that fast neutral atoms (or molecules) and the above described, slow, interfering ions are separated to the z the sample ions to be removed.
