Are these FID issues only with this instrument or with others in your lab as well. If this is only on this instrument it might have to do with the H2 or air EPCs. If it is on other systems as well, you might want to check your instrument air. I have seen…
Larger are the orifices of the cones, particularly the sample cone, more chance you have to get the IF/Bk pressure errors. Usually when the sample cone is too used then is passing too much air or whatever trough it at the interface, and the ICP senses…
Hi, I am using a 6890 GC in split mode with an isothermal temperature and no flow ramp and operating in constant pressure mode. Please can you advise how using the setting constant makeup flow for the FID detector is different to constant column and makeup…
I have a GC 6850 with an FID. I'll have to upgrade to Windows 10 soon, because Windows will no longer provide security updates for Windows 7. If I upgrade my computer to Windows 10, is there a ChemStation version that's compatible with the 6850 and Windows…
Hi!
I've got a SEQ type CC that should be calculated only once during the reprocessing and a peak or group type that uses the result of the SEQ one. Since this the SEQ type CC is calculated inj number * peak number times.... is it possible to avoid…
Hello,
I have inherited a 5975 MSD and when I go to autotune, there are no peaks present and the tune fails. I get alternating errors "Gain and Offset = 0 and peaks are too narrow" or "Tune action stopped: The valid Range for Ent Lens Offset is 0…
I'm a new GC/MS user and I have the following error: Inlet: Pressure Pre Shutdown warning after changing the column of a Intuvo 9000 Device. The total flow target of 4mL +/-2mL/min fails and the leak rate doesnt' reach values below 11mL/min. Can anyone…
We are trying to validate a new method, and our area counts are low and inconsistent. Our Hydrogen is from a generator and goes through an indicating filter. I replaced said filter recently, and am seeing it respond to moisture fairly quickly. How often…
It may. I'll review the Report Template Editor Concepts Guide and your post (@wydnaa) and see how this works .As for how we would calculate this manually, I'd just divide the result but the expected value (in our case 0.02 ppm) and multiply this by 100…
I'm trying to develop a method for ethanol via headspace. I am using Restek standard Residual Solvents #1 (34105) for the curve. My instrument is Agilent 6890 GC-FID with CTC PAL COMBI autosampler for headspace.
I ran residual solvent curve at high…
