Reduction of Mass-Dependent Interferences in Inductively Coupled Plasma-Mass Spectrometry by using Flow-Injection Analysis

Abstract
The use of flow-injection analysis to reduce mass-dependent interferences in inductively coupled plasma-mass spectrometry has been assessed. Results are presented which demonstrate nearly complete elimination of analyte-signal suppression under operating conditions where dispersion (D) is approximately 25. Furthermore, results obtained with flow-injection analysis exhibit greater precision, take less time, and suffer only a 40% reduction in sensitivity, compared to continuous-flow analysis.
