Injector and pressure problem 5890 Series II plus
Posted: Sat Sep 10, 2011 10:08 pm
I have a 5890 Series II Plus that we are trying to get running, this GC hasn't been used in years.
I have two injector ports, A and B, Injector B is running well, but Injector A is not working at all.
The pressure on injector A won't go over 0.3 psi, I checked the gas feed and no luck. I did notice that on my manual total flow control I have no gas out on the Split vent nor on the Purge Vent. I disconnected the manual flow controller and noticed that there is no gas on the outlet, replaced the controller with another used one, and same trouble, my inlet is working fine since when I unplug it and turn the gas on, there is gas coming out.
I also checked the column flow on the electronic flow module and it reads 5.35 ml/min, I tried changing it without success, I closed the gas and still have me a wrong flow reading.
Any suggestions?
