Reliable and Efficient Sulfur Detection in Proteins Using ICP-MS with Capillary LC

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.
