The aim in high performance liquid chromatography (HPLC) and gas chromatography (GC) is to get good peak shape and good separation. > To unsubscribe from this group and stop receiving emails from it.

It is written in C++, using wxWidgets, and providing bindings for Python and other scripting languages. The number I obtain from the peak at the right of 550 nm is roughly the same as the peak at the left of 600, (10.3731 and 14.643 respectively). It operates either as a command line program or with a graphical user interface. It runs on Linux, macOS, Microsoft Windows, FreeBSD and other platforms.

įityk is free and open source, distributed under the terms of GNU General Public License, with binaries/installers available free of charge on the project's website. It is also used in other fields that require peak analysis and peak-fitting, like chromatography or various kinds of spectroscopy. Originally, Fityk was developed to analyse powder diffraction data. Quantitative analysis of XPS data requires fitting of curves corresponding to different chemical states with appropriate spectral lines. These methods involve: mechanical cleaving, epitaxial growth, chemical vapor deposition, tearing of carbon nanotubes and reduction of produced graphene oxide (GO) from graphite and/or exfoliated graphite, direct exfoliation of graphite in a solvent.

It is positioned to fill the gap between general plotting software and programs specific for one field, e.g. X-ray photoelectron spectroscopy (XPS) is a widely used tool for quantitative analysis of surfaces, providing critical information about elemental composition and the chemical state(s) of each element. Fityk is curve fitting and data analysis application, predominantly used to fit analytical,īell-shaped functions to experimental data. The use of X-ray photoelectron spectroscopy (XPS) makes it possible to separate the states of carbon atoms ( sp1-, sp2-, sp3 -hybridization, various C-C and C-O bonds) in the surface layer of the sample by analyzing the binding energy of photoelectrons and using these data to calculate the fraction of amorphous carbon in the surface layer.
