MS status stays at "waiting for inlet start 1" after injection - WKB668

Article number: 668

SYMPTOMS

  • AutoSampler makes injection
  • LC method starts
  • MS method or detector does not start
  • MassLynx status (bottom of sample list page) remains at "Waiting for Inlet start 1"

ENVIRONMENT

  • All MS instruments
  • Quattro Micro
  • ACQUITY QDa
  • MassLynx
  • ACQUITY UPLC

CAUSE

Inject start cable is connected to the incorrect I/O port or disconnected (on the MS or detector) so the Start signal cannot be received

FIX or WORKAROUND

Plug the inject start cable(s) into the Event In 1 I/O port on the back of the Mass Spectrometer and/or detector.

ADDITIONAL INFORMATION

In the inlet method, under Tools > Configuration > Events > Triggering, select Event in 1.
