Title: the meaning of model masses in peak table
Post by: msss on May 19, 2021, 10:52:57 PM
Hi Hiroshi,

I would like to know what is the meaning of model masses in peak table?
why different sigma value lead to differnt model masses?

Thanks in advance!

Best regards
yang

Hi Yang,

the chromatogram peak of model mass is used in the deconvolution process.
The selected peaks to determine the model mass will be different if the sigma value is changed.
You can see the theoretical background from the below link.
