Spectral and physical interferences in a new, flexible inductively coupled plasma mass spectrometry instrument

Abstract

Different types of interferences in inductively coupled plasma mass spectrometry have been studied on a non-commercial instrument and compared with those reported by other workers. Spectral interferences from plasma and matrix background ions are similar, although relative intensities differ. The extent of formation of oxide and doubly charged ions is quite different from those reported in the literature. Chemical and physical interferences seem not to be present on the new instrument.
