The Long Neglected Cycloidal Mass Analyzer
Cycloid mass spectrometers offer powerful advantages for isotope ratio measurements, including double focusing (mass and energy), linear mass dispersion over a large spatial area, and a small footprint. However, the linear cycloid has not been adopted as widely as other mass analyzer designs, in part because of challenges with utilizing common ion detectors such as electron multipliers and Faraday cups. Integration of a linear cycloid with a capacitive transimpedance amplifier detector arrays can overcome these challenges, resulting in a compact powerful mass spectrometer for precision isotope ratio measurements.
