Soot is widely regarded as one of the most important air pollutants because of its occurrence in all urban areas and its impact on the environment, climate, and human health. These results add useful information and characterization of the soot, a relevant component of the ambient air, and its different features with respect to the urban or rural–suburban areas.Ĭopyright 2014 American Association for Aerosol Research A similar aspect emerges for the pure black carbon particles, mainly crystalline, and the black carbon particles associated with minerals, generally disordered.

The population of soot collected at the urban site, where the vehicular emission component prevails, exhibits mostly crystalline characteristics (with a D1 FWHM of 150–155 cm −1), whereas the population collected at the rural–suburban site, particularly the coarse fraction, shows a prevailing amorphous nature (with a D1 FWHM of ∼175 cm −1). Statistical analysis of the full-width at half-maximum (FWHM) values of the bands, as well as of their intensity ratio, revealed the presence of two classes of soot particles that can be ascribed to a different degree of crystallinity.

A careful examination of the spectral bands, performed with a five-(Voigt) curve deconvolution model previously described by the literature and here adapted to the purpose, lead to the characterization of the graphitic and carbonaceous material plus the identification of the mineral particles associated with it. To summarize, Fityk is a comprehensive and efficient application that is meant to help users perform nonlinear data fitting using as a basis the results of experiments from numerous fields of scientific activity.Airborne particulate matter samples were collected in an urban and a rural–suburban monitoring stations of the city of Rome, Italy, and the particles were analyzed through the Raman microspectroscopy.

The tool allows users to exclude inactivate points from fitting operations and work with several datasets simultaneously. Moreover, Fityk enables users to perform 'Power Diffraction Analysis' using 'X-Ray' or 'Neutron' radiation and various wavelengths ('Cu', 'Ag', 'Mo','Fe', etc). The utility allows users to execute a script, use data point 'Transformations' or adjust the preferred 'Functions', with the possibility of choosing between a wide range of options, such as 'Quadratic', 'Cubic', 'Gaussian', 'Lorentzian', 'EMG', 'Polyline', 'ExpDecay', 'Voigt', 'Spline', 'DoniachSunjic' and many more, while also letting users create their own. Users can work in 'Data Range', 'Add Peak' or 'Baseline' mode, according to their needs. The interface of Fityk is quite easy to understand, offering a toolbar for quick access to the most commonly used functions, as well as a menu bar, a main plot and a right-size panel where certain values can be edited.įityk provides users with several fitting methods, namely 'Levenberg – Marquardt', 'Nelder - Mead Simplex' and 'Genetic Algorithm', which can be of use in multiple analysis. These require a bit of documentation before being able to work with them properly, as such it is less approachable for novice users, though the more advanced can certainly appreciate its complexity. The program is fairly simple to work with, requiring minimal levels of knowledge or experience with similar tools, yet it features a set of rather complex functions. It is aimed at experimental data resulted from a variety of domains, like chromatography, spectroscopy, crystallography and many others.
