Recently I have been assembling the method ASTM D2425 '' Standard test method for hydrocarbon types in medium distillates by mass spectrometry ''. In this method I have had difficulties in calculating the variable '' P '' (Polyisotopic mixture peak). When I see the example that this standard shows, it is unclear how this value is calculated.
I would appreciate any collaboration
