A new inductively coupled plasma mass spectrometer with an enlarged sampling orifice (1.31-mm dia.) and an offset ion lens yields very low levels of many troublesome polyatomic ions such as ArO(+), ArN(+), Ar2 (+), ClO(+), and ArCl(+). The signals from refractory metal oxide ions are ≈ 1% of the cor
