Comparison of three techniques for analysis of data from an Aerosol Time-of-Flight Mass Spectrometer

► Comparison of three techniques for ATOFMS data analysis: PMF, K-means and Art-2a. ► PMF is applied, for the first time, to individual particle mass spectra. ► Efficient mass spectra deconvolution by single particle PMF analysis. ► Extraction of different organic families and two EC contributions. ► Results have been compared with independent measurements.
