Hello blairchall ,
I’m sorry for the delayed reply to your message. Do you still need assistance with this? If you do, please take into consideration the notes below. However, if the issue was resolved, could you please share what the resolution was…
We use Agilent NGA Analyzer GC based on 4 column configuration. Hayesep Q pre column, Hayesep Analytical column, molsieve column for TCD and one capillary column for FID. The H2S elution takes place in the Hayesep analytical column. But now a days our…
H ztarbs,
The air would not be for an inlet supply. This is most likely a detector support gas for FID. Check your method to make sure that the FID is not on in a standby method. FID air consumption is 400 to 450ml/min when on.
Regards
James
Hello, all you need to do in the method is to uncheck each of the FID flows, and uncheck the electrometer and uncheck the Flame on. With everything unchecked for the FID settings the software will ignore your FID. Under the Signals section you will also…
Thank you for your response Today when you open the GC we noted the increase returned valid but not connected and the Remote LED off we tried to configuration instrument but a message appears(failed to connect to 6890 at 100.100.100.101)but the GC IP…
Hi again
try the last hope ,
first try to select your reporting method in ( DA report template ) , the sequence accept it but i don't know if it will success to print ,
you may try it
the second thing if the first failed ,then try to edit your…
I want to check Total hydrocarbon by FID without identifying the hydrocarbon species . Agilent suggest to give me DB-1 15m, 0.32mm, 0.10u as a non polar column to elute all HC without separation as one peak . Does this column will work for Total hydrocarbon…
Hi silencer2008,
the 1 µL/s rule means the injection speed used for splitless injections, which is very slow compared to split injection where you want to inject as fast as possible.
Two interesting articles would be:

We've been having issues with our 7890B gas chromatograph. We have it connected to a workstation running Windows 7 SP1 and OpenLab/Chemstation version C.01.07 [27]. We have a Gerstel MPS attached as a headspace sampler.
We have been trying to run…
