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.
