Abstract

A solventless, multi-element, steady-state optimization system is presented. The device uses three parallel conduits that contain solid NbF5 and SnBr4 as well as a low wattage tungsten filament loaded with Pb to deliver dry vapors to an ICP. These are used to create a steady-state signal containing the following ions that can be used for tuning: 28Si+, 79Br+, 120Sn+, 184W+, and 208Pb+. In comparison to using a nebulizer for optimization, the dry plasma optimization produced an average enhancement of 4.5(±0.4)-fold for 26 elements when using electrothermal vaporization sample introduction.
