Advances and applications of ICP-MS for food and environmental analysis
In this webinar, Professor Brian Jackson, research professor in earth sciences and Director of the Trace Element Analysis (TEA) Core, will discuss developments in inductively coupled plasma mass spectrometry (ICP-MS) as a result of using helium collision mode. In addition, he will explore the utilization of reaction cell technologies such as those employed in modern triple quadrupole instruments.
Helium mode is generally very effective in reducing polyatomic interferences across the mass range but at the expense of a reduction in analyte signal intensity. However, helium mode is not effective for doubly charged interferences. The use of reaction gases to either shift the interference or to shift the analyte to a new m/z can be very effective in removing interference and retaining analyte sensitivity. Furthermore, it is an effective method for combatting double charge interferences.
This webinar will also cover examples of extending the utility of ICP-MS through the use of enriched stable isotopes, and the coupling of GC, LC and laser ablation with ICP-MS. In addition, applications for the speciation and spatial analysis of arsenic, cadmium, and mercury in food and environmental systems will be given.

Presenter: Professor Brian Jackson (Research professor in earth sciences and Director of the Trace Element Analysis (TEA) Core, Dartmouth College)
Professor Brian Jackson received his BSc in chemistry from Oxford University, UK and his PhD in soil science from the University of Georgia, USA. He has been involved with method development for ICP-MS for 27 years, using the technology to study arsenic and selenium speciation in coal fly ashes, poultry litter and sewage sludge as part of his PhD studies. After a brief spell as an ICP-MS product specialist for PerkinElmer, he returned to the University of Georgia as a research scientist and ICP-MS manager. In 2005, he joined Dartmouth College, where he is currently a research professor in earth sciences and the Director of the TEA Core.
