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…
Hi all,
We are running a 7890A/5975C GC/MS. The instrument runs when in split mode, but when switched to splitless the sample will not inject. We have always run splitless injections. The instrument will be initially ready and becomes not ready just…
Hello Community,
I've been analyzing unsaturated HC's in natural gas on a HP-PONA (GC-FID). One of our customers has requested a few alkene components (ethylene & propylene), so I shot a standard with those analytes + C2H2 and 1,3-butadiene.
It…
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…

Hello,
You would need to do a custom calculation to get that result. See the example below. I show 2 ways to do the total area calculation. The first is using the peak status as a time reference the other is by the compound name.
By Is time reference…
My question is for Mr. Ken and the community (if you're confident in your answer): Regarding the ASTM Enhanced Mechanical Calibration for Dissolution apparatus, while the USFDA clearly recommends this method as an alternative to the traditional USP PVT…
Hello community,
I have the following error (attached images) when start either offline or online mode. As you can see, the module control panel also dissappear. I have checked all the conections between PC and all modules and the error window continue…
