Managing doubly charged rare earth element interferences in single quadrupole and triple quadrupole ICP-MS

Of the three types of spectroscopic interferences in ICP-MS (polyatomic, isobaric, and doubly charged), there is a greater focus on doubly charged due to the use of rare earth elements (REE’s) for high technology devices. However, there are concerns with using REE’s, as the process of mining them may potentially lead to an increase in leaching into various water sources, soils and uptake by plant materials.

Collision/reaction cell (CRC) technology has successfully reduced most polyatomic interferences. Isobaric interferences may be avoided using alternate isotopes, and in most cases, doubly charged interferences can also be avoided using alternate isotopes. However, in some cases, no isotope exists that is completely free of doubly charged interferences.

In this webinar, Craig Jones, ICP-MS Application Scientist at Agilent Technologies, will discuss the procedures to correct for doubly charged interferences using equations with half mass correction using single quad ICP-MS, and the utilization of triple quad ICP-MS technology using reactive gases to eliminate the bias when doubly charged elements are present.

Key learning objectives

• Discover why rare earth elements (REE) are a potential issue in ICP-MS analysis
• Understand how to correct for doubly charged interferences in single quad ICP-MS and triple quad ICP-MS
• Learn how half-mass correction and reactive gases can both be used to correct for REE bias when doubly charged elements are present

Who should attend?

• Labs performing REE analysis
• Labs investigating REE analysis in lithium-ion battery industry
• Researchers looking at REE in geochemical samples
