System stopping after first injection during the syringe purge: dirty glass syringe
After starting a Triplus RSH headspace method, the run stops after approximately two minutes.
- The Triplus RSH Headspace sequence injects the first sample then stops.
- It was found that the Triplus RSH Headspace Syringe was dirty.
- The optical sensors used to purge the syringe after injection could not detect that the syringe plunger had moved thus causing a fault.
- The solution was to install a clean syringe.
