Abstrakt: The effect of plasma electron impact on negative secondary ions is investigated by example of a sputtered H3BO3/Cu powder pellet. O–, BO–, BO+, and B+ tertiary ions, fractured from strongly forward focussed secondary BO2 – ions, are identified by their kinetic energies. Since most of them are accepted by the ion optics, this process may affect quantification in HF-plasma SNMS. [ABSTRACT FROM AUTHOR]
