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…
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…
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 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…
Won't start without a "Mating Connector"
I use RS232 to control the pump. The mating connector is not present,
The manual says short pins 4 and 5 and pins 8 and 9 of the IO port.
This results in ramp-up and fail.
What is the correct wiring for…
Hi, We observed an error during autotune of QQQ GCMS as "Peak width gain failed", When it was occurred and what is the reason for the repeat error, Autotune was not completed due to " Peak width gain failed".
Please suggest the recommendations and possibility…
Hello Michael,
It's kind of a yes and no answer. Technically, the wavelength calibration will have failed because the strontium wavelength was not found - so you will see this if you check the results. Practically this is unlikely to impact operation…
Hello,
Our 6545 QTOF has been idle for a few weeks. When I checked the computer today, I found that "communication failed" errors had started appearing a few days after the instrument was last put to Standby. I'm not sure what happened as I don't think…
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…
My manager is wanting me to add pass/fail system suitability assessments to my reports/processing methods. In order to limit my validation work and minimize the number of report templates that I am maintaining, I am trying to keep the report adaptive…
