0 Answers I have a Series II 5890. I can run 3 or 4 runs without a problem. On the 5th run, I will get a fault on the Injector temperature. The temperature will read an absurd number (850 degrees). It should be in the 200 degree range. I am wondering if this problem is related to the temperature sensor at the injector, or is it possible that it is a "board" issue. Has anyone seen this?

2 Answers We've been using HP 5890 GC's (TCD & FID) w. split/splitless inlet and manual pressure controls with success.

We've recently purchased a refurbished HP 5890 GC Series II Plus w. EPC and I can't find clear instructions on how to set flow and/or pressure. There are two screens in the software I would appreciate guidance with: 1) Inlet Pressure Program screen 2) Packed Column flow control screen I don't know the relevance of 'Packed Column' flow control since the GC came with a megabore 0.53um column although we plan to switch to a 0.25mm x 60m column. We plan to use capillary, not packed columns??

There is obviously interplay between the keypad and the software. Changing the intlet pressure on the keypad produces a change in flowrate measured at the FID outlet, and the 'actual' pressure reported on the Inlet Pressure program screen changes, but I don't know how to do the reverse.

On the 'Packed Column Flow Control' screen, I've entered three sets of Press and flow reading, from which the software correctly calculates an equation relating the two variables. On the Inlet Pressure Program screen, I can Enter Values such as Column Length, Column diameter, Gas and then?? so what now?

There are buttons on this same screen labelled 'Pressure', Flow, Split Flow/Ratio?? then what?

If anyone can direct me to a set of instructions of video explaining how to set this up, I'll be very grateful

0 Answers My lab is equipped with a few 5702 R centrifuges and a request has been made to operate them without brake. I can only find documentation about the soft ramp settings, which is the closest thing to "no brake" that I can find. How does this compare in actuality to a no brake spin?
