Article number: 69828

SYMPTOMS

  • Pump pressure is normal when equilibrating system
  • Pump HW overpressure error occurs within a short time of starting a run

ENVIRONMENT

  • 3100 Mass Detector
  • SQ Detector
  • SQ Detector 2
  • TQ Detector
  • Xevo TQ MS
  • Xevo TQD
  • Xevo TQ-GC
  • Xevo TQ-S
  • Xevo TQ-S micro
  • Xevo TQ-XS

CAUSE

The tubing from the diverter valve to the probe is blocked or kinked. When the diverter valve switches from "waste" to "LC" during a run, the overpressure error occurs.
