In the Offline Worklist Editor for MH12, when using the "Edit Samples" window to input the sample positions, the "Current Configuration" box in the top left isn't shaded out, so that I can't choose it. When using Acquisition to do this same function,…
5 psi inlet pressure running hydrogen with your configuration leads to 2.3 ml/min to the MS and 1.02 ml/min to the FID.
You are welcome. Are you using a two-hole ferrule in the injection port or a splitter of some type? The two-holed ferrules are..…
Richard987 A normal EPC module could probably supply the nitrogen to the collision cell but it's not tested, not supported, no one knows as it's never been done. If you can run it now and MassHunter Acquisition isn't complaining it might work.
How long…
Which liner is being used? Check out: GC Liner Selector | Agilent You should think about trying one with a frit instead of glass wool, like this one: 5190-5105 | Agilent Or a single tapered, ultra inert liner 5190-2295 | Agilent .

Hi JPhillips - in our latest software (QTOF Acq 12.1) - it is much easier to copy and paste the entire "Sample Name" column into the data file column. All rows in the data file column will automatically receive the .d suffix in one action (the paste command…
Hello GUX ,
For these types of errors the first thing to try is resetting the user preferences for Profinder. To do this, first close all copies of Profinder and then navigate to the folder

The error means that the maximum stroke length of your pump drive is being shorter than it should be.
This can be either due to mechanical issues like a broken piston or an offset in the pump drive gear leading to a physical block before the normal…
Hello aafzal3 ,
I apologize for the delayed response.
You can use either find by method to attempt to find your targets, but to troubleshoot the issue you need to find your target manually by extracting the EIC for the expected molecular ion. Once…
The best way to troubleshooting signal issues is to separate the flow path from the light path as good as possible.
With your detector this would require the use of the dedicated Max-Light cartridge Test Flow Cell # G4212-60011.
In this way you can…
Hello,
I Have performed Dwell Volume calculation with the attached method.
I calculated dwell volume in some different ways.
1) Saved CSV file from Lab Advisor and calculate 50% of height from it. I got 1186mkL.
2) From This tools attached above…
