Although quadrupole mass analyzers represent more than 90% of all inductively coupled plasma mass spectrometry (ICP-MS) systems installed worldwide, limitations in their resolving power has led to the development of high-resolution. spectrometers based on the double-focusing magnetic-sector design. Part VII of this series on ICP-MS takes a detailed look at this very powerful mass separation device, which has found its niche in solving challenging application problems that require excellent detection capability, exceptional resolving power, or very high precision.
