Substance composition
»  How many substances incl. excipients, impurities, etc (e.g.15 compounds)
»  Their putative molecular masses (e.g. Mr=474 of compound 1)
»  Approximation of their content (e.g. 10-2 g of compound 1)
Identification of
brutto formulas
of substances
incl. excipients,
impurities, etc

(e.g. C22H30N6O4S of compound 1)

Structure
determination
of substances
incl. excipients,
impurities, etc
(e.g.structure of
