This study investigates the applicability of a quadrupole-based ICP-MS fitted with a dynamic reaction cell (DRC) to analyze high-purity phosphoric and sulfuric acid used in the semiconductor industry. It compares the DRC approach with traditional ICP-MS background reduction techniques to compensate for phosphorus- and sulfur-based interferences and presents data that suggests that the DRC technology can reach the next generation of semiconductor purity levels for these chemicals.

There is far more matter than antimatter in our universe, but scientists don?t know enough about the properties of antimatter to understand why. By spectroscopically analyzing atoms created when antiprotons collide with helium, physicists at CERN are measuring the properties of antimatter with unprecedented accuracy.
