Short summary

The applicability, methods and limitations of constrained peak fitting on mass spectra of low mass resolving power (m∕Δm₅₀ ∼ 500) recorded with a time-of-flight aerosol chemical speciation monitor (ToF-ACSM) are explored. Calibration measurements and ambient data are used to exemplify the methods that should be applied to maximise data quality and assess confidence in peak-fitting results.
