Sample Introduction Using the Hildebrand Grid Nebulizer for Plasma Spectrometry

摘要

The Hildebrand grid nebulizer is evaluated for use with Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) and Mass Spectrometry (ICP/MS) detection. Limiting aspiration rates for various organic solvents were determined for the grid nebulizer with a mini-pyrex spray chamber, a cooled spray chamber and a conical spray chamber. Detection limits and linear dynamic ranges were determined for various species. Indirect solvent transport efficiencies were determined as a function of spray chamber, flow rate, temperature and solvent. A comparison was made between the grid, cross-flow, concentric and glass frit. Three interfaces for volatile organic solvents used to couple Flow Injection Analysis (FIA) with ICP-OES detection were evaluated. Detection limits, linear dynamic ranges, precision, and peak width were determined for elements in methanol and acetonitrile solutions. Theses. (mjm)
