Yes, it is possible. Have you checked the filters on your results table like I mentioned in my last reply? Some tables will by default have filters applied to prevent group results from being reported. These filters will look like those in the below screenshot:
Timed groups have a compound_type of 3, so you will need to get rid of the =Compound_Type <> =3 filter if you want to report timed group results in the table.
If the "Compound used for quantitation (Main Peak)" option is checked in the Peak Filters section of your table's properties that might be what is causing the problem:
You can also play around with the Remove Duplicate Peak(s) peak filter. In older revision of the software this did not work perfectly though.
Try using the expression =compound_areasum instead of =peak_area
That's it! It worked for named group! Thank you very much!
One last question: what's the diference between timed and named group?
Thank you!
A named group is a group comprised of compounds that you have already identified in your processing method while a timed group is comprised of any integrated peak that falls within the time range in the group definition.
