Modernizing Nitrosamine Analysis with Advanced Electron Ionization

sponsored by Thermo Fisher

Nitrosamines are substances of increasing concern in relation to drinking water safety. As such, low level analysis of these challenging compounds is required. The main reference method (EPA 521) addresses this using a chemical ionization (CI) GC-MS/MS approach. However, the CI approach can present some challenges with routine analysis. Presented here is the use of a novel advanced electron ionization (AEI) source in conjunction with GC triple quadrupole mass spectrometry to provide a simple way to measure nitrosamines at low part per trillion (ng/L, ppt) levels as well as offering the opportunity to make significant method efficiencies during sample preparation.

Learning Objectives of Webinar

  • Learn about the analysis of emerging drinking water contaminants such as nitrosamines which have the potential for future regulation and therefore requirement for testing in drinking water labs across the world.
  • Learn about the advantages of GC-MS/MS technology for the analysis of nitrosamines in drinking water versus legacy chemical ionization and ion trap methods.
  • Explore how the latest in GC-MS ion source technology enables opportunities to increase productivity in the routine laboratory.
