Oxide and Doubly-charged Species：
Measured under identical operating conditions used to achieve sensitivity and detection-limit specifications.
| CeO+/Ce+ | < 0.025 |
| Ce++/Ce+ | < 0.03 |
Background Signal：Mass 220 < 1 cps
Short-term Precision：< 3% RSD
Long-term Stability：< 4% RSD over four hours
Isotope-ratio Precision：< 0.08*% RSD (*or within a factor of two of the counting statistics limit)
Mass Calibration Stability：< 0.05 amu over eight hours of continuous operation
Quadrupole Peak Hop (Slew) Speed：1.6 M amu/sec
Quadrupole Scan Speed：5000 amu/sec
Abundance Sensitivity：Measured at 238U
Better than 1.0 x 10-6 at low mass side of peak
