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 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

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…
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…
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, 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…
