Have you checked that your stock standards are not contaminated and tried a second source of SIC. Do you run He in addition to nogas and does it only fail for nogas but pass in He?
I've also seen Sb stick around in the tubing, autosampler probe, and…
Hello, How often does your reference amount for the compounds change? If it never changes or changes on an infrequent basis I would suggest using a constants file in custom calculator. Also we have seen syntax issues with expressions in IR when using…
When Air gap is 0.2 and the flow rate is 2.1 ml/min then the peak area found 287 by FID but when the air gap is 0 and flow rate is 1.47 ml/min then the area reduced to 141. Where analysis performed by Autosampler.
Hello,
That will work but what value are you displaying? If you want the logic to be if any injection fail it shows unmet then you would need to store and evaluate the logic. I would have a hidden column that converts met and unmet to 0 and 1. You…
I have the headspace autosampler 7697A attached to a GC 7890A. I have two issues. the first is a growling noise when the gripper moves in the downward motion. Not the entire way just the middle third. I am guessing a service call will need to be made…
I think we do this at my lab but not with a valve. We use a plot column and anayze headspace above a water sample. We test for methane ethane ethene and propane useing an FID. The integrated gastight syringe with a valve in it from Fisher helps. We use…
Hello, Finally we were able to resolve, for some reason the scheduled task that is supposed to generate the certs at startup was failing. Recreating and running the task fixed the certificate after rename issue, and now the client is able to connect to…
Hello Mark, You need to configure user tune. Click on the Settings widget, then Options, Selected Options and check User tune. Close Settings. Go to the Plasma widget, click on the drop down arrow and select Configure Ignition Sequence .Select user tune…
Hi All,
I was trying to perform the Sampler Leak Test on the G7167B 1290 Multisampler. Whenever it reaches the last portion of the leak test (Blindseat leak measurement) the pressure just could not build up and the whole Sampler leak test will fail…
Hello,
Please try replacing the torch. If that does not resolve your issue, please contact Agilent customer support to begin the process of opening a repair service order. It is possible that your waveguide has failed. Have a great day
