With its advantages-compared to ICP-MS-in matrix tolerance, robustness, simplicity, and cost, ICP-OES may be the technique of choice for the analysis of medications with low daily doses. For such analyses, the use of high-pressure, high-temperature microwave digestion in sealed containers simplifies sample preparation and prevents the loss of volatile elements.

This study reveals the potential of triple-quadrupole ICP-MS for reliable quantification of noble metals at ultratrace levels even in difficult matrices.The effective use of reactive gases for interference removal and a thorough and effective protocol for sample preparation and handling are essential.

When using a triple-quadrupole ICP-MS system, the increased abundance sensitivity of MS/MS mode makes it possible to measure trace elements using isotopes that would otherwise be affected by peak tailing from an adjacent major element. This approach is illustrated using the example of ultratrace 237Np analysis in the presence of 10 ppm U.
