Hi Carol_Ultivo , There is always a trade-off or balance to be struck 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…
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 ,

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…
Please give more information. TSU - is that Thermal Screening Unit? You say under varying pressures...from zero to how many PSI/Bar? Will you need to use a vacuum to get the sample? Will this be analytes in air or something else? Decomposition of what…
Did the EM get replaced March 15? Or a source cleaning? The EMV went down 883V.
The Ent Lens (Entrance Lens) those jumps from 16 to 63,32,47.5 .. and the Ion Focus going from 80's to 40's... make me jumpy. Something was changing. When were source cleanings…
