I have a question about interferences on ICP-MS. I have tried to induce interferences using 6020ICS-0A at 1:10 and 1:100 dilution. I have been looking for interferences with Cu, As, Zn, and Cr. 6020ICS-0A has many of the interfering components for these metals, but I can't induce the interferences at these spike levels In routine ICP-MS analyses, two types of interferences exist: non-spectral (physical and matrix effects) and spectral (isobaric and polyatomic). Let's look in more detail at both non-spectral and spectral interferences The types of interferences that go beyond the capabilities of single quadrupole ICP-MS include the so-called isobaric interferences, consisting of isotopes of an element that have the same mass as isotopes of another element (such as 87 Rb and 87 Sr) and intense interferences generated by samples containing very high levels of matrix elements, such as metal alloy digests

Spectral interference can be categorized as follows: Molecular ions from Argon (ArO, ArH, ArOH, ArN, ArCl, ArC, ArAr etc Triple quadrupole ICP-MS offers some potential for solving these interference problems, but I believe that the usual approach of mass shifting Se to SeO using O2 as the collision / reaction cell gas may not work in this case as Ge also reacts with O2 (although I don't yet know how efficient this reaction is)
Plasma Gas Interference: ICP-MS is a technique capable of quantifying up to 75 different elements.

Single quad ICP-MS, such as the Thermo Scientific™ iCAP™ RQ ICP-MS use helium and kinetic energy discrimination to remove all polyatomic interferences, potentially causing a bias on key contaminants. In contrast, triple quadrupole ICP-MS systems, such as the. In ICP-MS, the signal for a specific isotope of an element is often obscured by overlapping signals due to background gases or compounds producing isobaric ions of nearly identical m/z. A common problem arises with argon oxide and iron with m/z values of 55.9573 and 55.9354, respectively ICP-MS serves as a powerful elemental detector for accurate and precise analysis, especially for quantification purposes.
