We have a baseline that gives a sinusoidal wave that starts about 16 minutes. We are using an Agilent 6850 GC with a split/splitless injector and an FID. The inlet is interfaced to a 7679A HS. The baseline is good up until 15.5 minutes then it starts…
Hi Ran,
Thank you for contacting us and I am sorry to hear that you are observing this issue. Based on the symptoms observed (low signal intensity causing the lower markers not to be detected combined with the autofocus failure) may indicate hardware…
Hi, Howard Sanford
Thank you for your replay. The version of MassHunter (MH) Data Acquisition and quantitative analysis programs software is B.07.00.
Unfortunately, there isn’t any error code for this problem. But a window with “The head of file could…
I am getting message "draw command failed, EE34205" while running batch in G7129B infinity 2 autosampler. I have tried replacing transport assembly, but error is same. I have used another module G7129A Infinity autosampler with this LC, but same error…
Hello,
We are having an issue with our 7890B GC back inlet. The inlet temperature and flow were both set to "OFF," but the back inlet kept heating up while were were trying to run the front inlet (in GC-FID mode). This resulted in a thermal shutdown…
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.

James
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…
