Accurate, Low-Level Sulfur Analysis by ICP-MS Using MS/MS with Oxygen Reaction Cell Gas

September 01, 2020

Combined with appropriate selection of instrument components to reduce the sulfur background, ICP-MS using MS/MS with oxygen reaction cell gas can provide accurate low-level analysis of sulfur and sulfur isotope ratios in aqueous and organic matrices. This is useful in applications in life science, clinical research, pharmaceutical development, food safety, environmental monitoring, geochemistry, and petrochemistry.

Using Double Mass Selection and Reaction Cell Gases to Resolve Isobaric Spectral Overlaps in ICP-MS

September 01, 2018

When using a triple-quadrupole ICP-MS system, the increased abundance sensitivity of MS/MS mode makes it possible to measure trace elements using isotopes that would otherwise be affected by peak tailing from an adjacent major element. This approach is illustrated using the example of ultratrace 237Np analysis in the presence of 10 ppm U.
