Abstract
Each estimated composition candidate is evaluated based on a mass spectrum produced using soft ionization and a mass spectrum produced using hard ionization. In the evaluation, a comparison between two measured isotope patterns (primary pattern matching), and a comparison between the measured isotope pattern and a theoretical isotope pattern (secondary pattern matching) are applied stepwise.
