Analysis of the compositional variation in living cells is essential for understanding biological processes. Single-cell elemental analysis by triple-quadrupole ICP-MS is emerging as a selective, highly sensitive, and potentially high-throughput technique for the study of constitutive elements, and uptake of metallodrugs (or metal-containing nanomaterials) in single cells.

With recent research, the University of Oviedo's analytical spectrometry research group has taken a step closer to the absolute quantification of proteins. Quantification based upon isotope dilution mass spectrometry of sulfur is hampered by gas-based polyatomic interferences. By implementing a quadrupole inductively coupled mass spectrometer with collision/reaction cell technology, the group has been able to overcome the issues and has increased reliability while optimizing the efficiency of its analyses.
