Very low (pg kg-') concentrations of most elemental impurities are determined in an arsenic matrix by spark-source mass spectrometry when working with a cut ion-sensitive plate. The mass spectrum of arsenic is relatively simple and the lines for almost all analytically important ions are interferenc
## Abstract Environmental samples such as soil solutions contain inorganic ions such as ${\rm{NH}}\_4^+$, K^+^, Na^+^, ${\rm{NO}}\_3^-$, and ${\rm{PO}}\_4^{3-}$ in high concentrations, which must be removed prior to capillary electrophoresisβmass spectrometry analysis to obtain accurate results. Ho
