Application Note: Enhanced Detection of Mercury Using the CETAC HGX-200 Cold Vapor / Hydride Generator with Quadrupole ICP-MS Detection
4 July 2016

The technique in this application note can offer up to 100 percent sample transport efficiency (vs. <5 percent for conventional pneumatic nebulizers) to markedly increase Hg sensitivity despite the higher ionization energy. The specificity of the reaction will also separate Hg from any nonvolatile interferences such as a WO+.
