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,
I have an Agilent 7700 ICP-MS running MassHunter 4.6. Interesting issue - the instrument tunes just fine but when I go to run a sample, the data acquisition never stops; it continues well past the time it should have taken including rinse program…
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…
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…
