Complex isobaric and polyatomic spectral interferences can be mitigated using triple quadrupole ICP-MS (ICP-MS/MS) with a collision–reaction cell (CRC). This configuration allows for the multielement characterization and detection of smaller nanoparticle sizes.

A challenging 15 hour sequence of high matrix soils, waters, seawaters and sediments was analyzed according to US EPA Method 6020A using a new ICP-MS designed for routine applications. With a single collision cell mode for polyatomic interference removal and superior matrix tolerance with an aerosol dilution system, excellent recovery of certified values for six SRMs with no quality control failures throughout the sequence was achieved.
