eng	Determination of Fluorine in Organic Pigments with the Use of Laser Induced Breakdown Spectroscopy	The aim of this work was to develop a methodology for the determination of fluorine in real samples of organic Pigment Yellow 154. Although several methods are successfully used for determining of fluorine, most of the methods require digestion of the sample. Unfortunately, transferring of fluorine into the solution is frequently not quantitative. It is therefore appropriate to use a method for the analysis of solid samples. A suitable method is laser-induced breakdown spectrometry (LIBS). Samples were measured in air, helium and argon atmosphere in the form of pellets and with a thin layer on the tape. Suitable modification appears as compressed samples to form of pellets, and the ablation chamber filled with helium. The limit of detection was determined as F 0.538% (w / w). The proposed method was successfully applied to the determination of F concentration in a real sample of organic pigment	Laser-induced breakdown spectroscopy;Fluorine;Organic pigments.
