There are well recognized difficulties in measuring nanoparticles (NPs) accurately by conventional single-quadrupole inductively coupled plasma mass spectrometry (ICP-MS), because many natural and engineered NPs are based on elements that are challenging to measure at trace level by ICP-MS, such as iron, titanium, and silicon. This month's "Atomic Perspectives" column discusses how complex isobaric and polyatomic spectral interferences can be mitigated using triple-quadrupole ICP-MS (ICP-MS/MS) utilizing a collision-reaction cell (CRC), allowing for the multielement characterization and detection of smaller nanoparticle sizes.
