Instrument never get ready and always in equilibrating stage
Hi,
I am suing GC varian CP 3800 with an autosampler CP 8400. I am having problem which the isntrument never gets ready and always in equilibrating stage even though there's no fault reported. All the parameter have reached the set points (injector, column oven, and detector temperature, flowrate and pressure), but the GC always says "not ready). Therefore i can't do any injection. Any suggestion for that case?
Thank you very much in advance.

Reply byI have checked all the status, all seems fine. The temperature, the gas flow etc, even the oven equilibrating time. There must be something not right, but i don't know which part as the software also saying "no faults". Any further suggestion would be appreciated.
Thank you

If you exit the software, does the GC go to a ready state?

Reply byHi Dan,
yes i did that and it's still the same, giving not ready sign. I even reinstalled the software twice.

Reply byWas there ever a fix for this problem? We started a few days ago to see Not Ready even though everything is at set point. We had not made any changes just before that.
We have two columns installed with their own injection ports and detectors. We can use one but not the other because of Not Ready on the flow for the column not in use for that method.
Help!
