Formulacolumn of the → target/suspect and → internal standard tables to calculate relevant isotopologue + adduct masses from them, you have two alternative notations to use screening masses directly. These notations may be used when screening for, e.g., GC EI fragments.
mass1 ... mass2 ... mass3are the different masses to be screened (these can be more or less than three, of course), with
intensity1 ... intensity2 ... intensity3denoting the relative intensities of these masses.
Nstand for "neutral"):
