If your area is relatively stable but your amount/result is low, you have to have either altered your calibration values, failed to clear a previous calibration, or omitted a dilution factor. Are all results lower by the same factor or is it variable…
7890A GC/5975 MS/E.02.02 SP2
Sequence is stopping constantly with the following log book message: "The run was stopped by the instrument's stop button or stop input. The GC Failed to Start."
Found that exact error in the KBR - " Known Problem Report…
I apologize because this is a very blind question- New IT guy to the company and previous didn't have good documentation on this application.
I have a user who is getting the attached error whenever they try and open Sequence Manager or open Bioconfirm…
New FID Jet!
The latest FID jet is intended for use in 6890/7890/8890/8860/8850/9000 GC models
The legacy jets will not work in the 8890/8850/8860/9000 GC models
The new jet makes installing the column seamless with a conical shape to direct the…
Hello
I am having a hard time trying to figure out how to only display one FID signal on a report from a dual injector GC system in OpenLAB 2.4. The calibration that was run used the dual injector setting, but when we were running test samples we only…
System: The GC is an 8890 with TCD in series of two FIDs in parallel (switched via valve). FID 1 has methanizer while FID 2 doesn't.
Had to put the system on standby for 3 weeks over Christmas so kept carrier flowing through the system with all heated…
This 6890 is code named FIDDY because of its dual Flame Ionization Detectors. The SF FBI donated it to UC Davis Chemistry over 10 yrs ago. It is used to teach Chemistry majors gas chromatography and replaced an old Varian 3800 with a chart recorder!
In detail, you can follow below link to resolve this type of problem.
