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…
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
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…
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…
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…
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…
Hello,
I am getting the following error on OpenLab CDS Chemstation Edition (Rev. C01.10 [287]): "User Change (Unlock) failed, because instrument access is not permitted for user. Logging Out User". We are initially able to login once, but then when…
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…
