Re: Filtering an area
For quantification, if each compound has some distinct ions, you may specify a quantifier and a response factor to calculate the total response. If there are no distinct ions, you may need to adjust areas to be tight around peaks. Alternatively, you may detect peaks on SIC manually or use the Proces...

Re: 50% peak widths or average 4δ peak width
Size I(50) is the Column 1 peak width at 50% peak height Size II(50) is the Column 2 peak width at 50% peak height There is no peak width computed based on standard deviation. Assuming all peaks are Gaussian, you may derive the relative peak height. For example, the following post shows that +/- 2δ...

Re: Undesired compounds
Depending on how undesired compounds mix with others, you may be able to add a polygon to subdivide the region or exclude the blobs of these compounds.
