We're running an old Dionex ICS-2000 for anions, water eluent, KOH EGC, AG 11 guard, AS11 column. Noticed high pressure errors last week and today the system will not run at all due to high pressure hardware errors and shutting down even at low flow rates.
Today I came into the lab to troubleshoot and noticed that both the instrument panel and the Chromeleon program we use to schedule samples reads high pressure ~1000 psi even with there is zero flow. I have tried disconnecting lines to see where the backpressure is coming from but nothing ever changes the reading.
Any ideas are helpful!
