Combining Helium Collision Mode, Aerosol Dilution and Discrete Sampling to Maximize Matrix Tolerance and Productivity in ICP-MS Analysis of Environmental Samples

Abstract

By combining recent advances in inductively coupled plasma mass spectrometry (ICP-MS) technology including improved collision cell efficiency, aerosol dilution and discrete sampling, a rare synergy has been achieved resulting in a system that is not only much faster than previous instruments, but also shows improved ease of use and superior matrix tolerance. This work demonstrates the benefits of such a system by demonstrating United States Environmental Protection Agency (USEPA) compliant analysis of a range of high matrix certified reference materials for 26 elements in less than 2 minutes per sample.
