Thank you very much for your quick attention. I take advice to use Labadvisor, however, the host computer is a windows 7 system and the built-in net framework is NE3.5, but LabAdvisor downloaded from Agilent site needs Net Framework version 4.7.2 , which…
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…
I am new to GC. I am trying to make a calibration table for a set of fatty acid standards using Agilent 8860 (GC-FID)
After the derivitization step, analysis of the resulting methyl esters shows only the solvent peak. Usually a very high solvent peak…
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…
Hello,
Does anyone know were the signal data for the live signal displayed in the online signal window is stored and/or how to access it in Chemstation Rev.B.04.03[16]? I would like to write a macro to run in the scheduler to periodically grab a live…
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…
