The carbon KLL spectra were analysed using the pattern recognition methods. The standard spectra were recorded for (i) surface tungsten carbide, (ii) bulk tungsten carbide, (iii) graphite and (iv) amorphous carbon. The set of these spectra was a basis for the process of recognition. The careful analysis of the set of standard spectra made possible construction of several procedures (classifiers) for recognizing the chemical form of carbon corresponding to a given spectrum. The KLL spectra of carbonaceous residue growing on nickel foil were analysed using all the developed classifiers. At the early stages of growth the carbidic form of carbon was recognized, followed by the graphitic form at further stages. This result agrees with observations reported in the literature.
