Thermo Fisher Scientific's webinar, 'Magnet or Cell: Fundamentals of High Mass Resolution and Collision/Reaction Cells and How They Cope with Challenging Matrices', is now available on-demand.
The webinar discusses the capabilities of inductively coupled plasma mass spectroscopy (ICP-MS) and how to overcome the challenges of spectral interferences.
It provides an educational overview of ICP-MS, followed by a discussion on the principles and advantages of overcoming spectral interferences using high mass resolution and collision/reaction cells.
Presenters give an objective comparison of these spectral removal strategies for challenging matrices using the Thermo Scientific Xseries 2 quadrupole ICP-MS and the Thermo Scientific Element2 magnetic sector field ICP-MS analysers.
Traditionally, ICP-MS is the preferred technique in routine environmental laboratories due to its wide elemental coverage, high sensitivity and speed of analysis.
In addition to its ability to determine elemental concentrations, the technique also offers high-precision isotope ratio determination and, if coupled to a separation device, it can also provide important species information.
However, there are limitations associated with ICP-MS, including spectroscopic interferences that can jeopardise the accuracy of results.
Among other things, the webinar discusses how to overcome the problem of spectroscopic interferences by coupling ICP-MS with a magnetic sector field analyser or collision/reaction cell (CRC) technology.
With high-resolution ICP-MS the analyte is separated from any spectral interference by identifying the mass difference between the two.
The Thermo Scientific Element2 is a high mass resolution ICP-SFMS delivering inference-free analysis and high data quality.
The Xseries 2 features advanced H2/He collision cell technology, licensed from Battelle, which provides multi-element analysis for all elements including Ca, Fe, As and Se.
The design of the Xseries 2 coupled to a CRC allows laboratory users to achieve analytical objectives faster, with greater confidence and with less hands-on time from the operator, according to Thermo Fisher.
