I'll just guess because you gave us very little information in my opinion.
But...It seems m/z 208 is shifted to more cc than it should. Maybe an interference with that m/z?
The 66x2mL tray has three white square plastic clips on its rear for automated identification by the sampler.
The 18x6mL tray just has one of the squares.
Please check your tray, i am pretty sure that some of these clips are missing.
You may will…
Okay, I just remembered - I didn't manage to change the size of the text in this program, it was in the Qualitative analysis program. So perhaps it is not possible to change the text size in this program. I really wish that feature would be added, for…
Hello Chalbrecht ,
I apologize for the delayed response.
There are a few options for naming the reporting output file using the sample or batch name with $(SampleName) and $(BatchFileName), but I don't see that the Sample Group is an option. You may…
Hello Achim_Hongenaert ,
I apologize for the delayed response.
There are a few outliers that can be used for recovery calculations. If this compound is added to all samples then I believe the best option will be to call it a Surrogate in quant, even…
Thank you, Linh, for your information. Given that it is an old machine, I am concerned about the potential loss of data if we upgrade the software. Instead, I will create a shutdown method to be executed at the end of the sequence run.
Hello,
I would like to ask if it is possible to execute the command "Created Compound from Each Selected Spectrum" in version B.10.0 of the Agilent MassHunter Qualitative Analysis software. This command is available in version B.07.00, but not in version…
Did you remove the diffusion pump, take it apart, empty the contents completely, wash them all with something like toluene, reassemble it with new diffusion pump fluid filled only to the top of the "cold" mark - if you didn't take it all apart and any…
Hello. Thank you howard_sanford for that answer! I talked to an Agilent technical representative and he came up with the same solution. But, we have the B.07.06.2704 version of Masshunter. What would be the data path for those files in that case? I am…
