Hi Carol, There is always a trade-off between Scan speed, mass resolution and sensitivity in any quadrupole mass filter. So if you decrease the resolution and keep scan speeds the same you will naturally get an increase in sensitivity. Based on the trouble…
What are the inlet and column configurations, flow rates, pressures, and timing setpoints? The fastest way to share that is to copy/paste the contents of the file acqmeth.txt that lives underneath your specific Our_Run_Method_Name.M subdirectory in Windows…
Yes - it was a bit of a mess - but I was able to fix it. Thanks for the heads up. Not everything could be fixed in the computer portion of the method. I had to go into the GC configuration and fix it there.
Thank you!
Thank you for the suggestions. Yes, some of what I'm doing does not require the ISTD but I leave it in the analysis method b/c of needing it in some of the work. I haven't had a chance to work on this in a couple of weeks, but will definitely keep it…
Hello Adrsto ,
I apologize for the delayed repsonse.
It is not possible to use the NIST algorithm itself within Unknowns Analysis. As you mentioned, you can adjust the forward and reverse settings and enable the Adjust Score option, which from the…
Hello Lstephan ,
I apologize for the delayed response.
Errors of this type generally point to an issue with a preferences file. The first thing to try is clearing these using the Restore User Settings tool found in the Quant Tools group in the start…
Hello AJohnson13 ,
This is a known issue if Acquisition has been pinned to the Windows Taskbar and run from there in MassHunter Acq Version 11.x and later. This is due to the OpenLab integration and the need to launch through Control Panel to include…
