System stopping after first injection during the syringe purge: dirty glass syringe
Resolve the issue of the Triplus RSH headspace method stopping after two minutes by addressing the dirty headspace syringe. The optical sensors fail to detect the syringe plunger movement, causing the fault. Install a clean syringe to ensure proper detection and continuation of the sequence.
Issue
