Managing doubly charged rare earth element interferences in single quadrupole and triple quadrupole ICP-MS
22 Jun 2023

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.
