Sensitivity Verification Failure in STD mode
Issue
Sensitivity verification failure in STD performance report
Environment
- iCAP Q
- iCAP RQ
- iCAP TQ
- ECCN: EAR99
Resolution
Performed Detector Setup: HV setup and Cross Calibration
Analysis
HV Setup and Cross Calibration should be performed at least once per month.
Cause
Detector voltages were too low. The first masses to experience degradations in sensitivity will be the higher masses so it is possible to attain passing sensitivity for Lithium, Cobalt and even Indium (to a lesser extent) and experience a failure on Uranium.
