Hello Guys, I am using Agilent 7890a GC with an FID detector. I using this GC in online mode to analyze reactor exit gases. I am currently studying the dehydrogenation of Methylcyclohexane over Pt catalyst. Recently I noticed that the FID response is…
Hi All,
We have a 5977 MSD which came up with two errors following a site power outage:
"Source Heater Error: Timeout - temperature fails to increase under full power." "Analyser Heater Error: Timeout - temperature fails to increase under full power…
We suddenly lost power during sample injection, when the power back, the autosampler got needle lock fail error message and fail to go back to needle seat, anybody could help? we did a cold start but not work.
This is absolutely the wrong column. Ammonia and H2S need apolar thick films to be separated and no specialized Free-Fatty-Acid-Phase (FFAP). A CP-Volamines column would do (CP7448) . Ammonia elutes just after CO2 and before water, H2S after water at…
For the GC-6890 FID detector issues you're experiencing, here's a simplified approach to troubleshoot the errors:
Gas Supplies:
Make sure all gas supplies (utility, makeup, hydrogen) are on.
Check that the pressure…
We have a GC-MA7890B with an FID detector and I are observing spikes in the baseline after we made a couple of changes.
We installed guard columns with unions on inlet and detector side, added a 2nd gas cylinder and required tubing, cleaned the FID…
Thank you for the help so far. I was able to solve the problem on my results table by using the "left outer join" function.
However, the report will not print the individual peak chromatograms for the target ion or qualifiers if there was no peak detected…
First off, it is not the barcode reading that causes the vial leaking, but my best guess is that the barcode reading introduces a variable time, that then can cause a scheduling conflict. This scheduling conflict is then not handled, and the 7697A is…
Hi,
1. It is not normal, that you have to purge the cell gas lines every time
2. Ou should perform at least following "Tests" during Plasma ignition: Torch Axis - EM - Resolution/Axis. But a performance report every day would be nice (and therefore…
I am building a report for some GC-FID data from a GC-MS/FID instrument. I have managed to build a report that contains the chromatogram and the table of peaks. I can scale the X-axis to the scale i need but I have been unable to scale the y-axis to show…
