One of the qualitative parameter of biofuel is purity. Measurement of purity of biofuels is very important. The reason is that the number and size of particles influence an engine life. However number and size of various particles have influence on the hydrodynamics and rheologic properties. In the first part of the paper is introduced the description of tested fuels, the method of measuring of number particles and size particles with use particle size analyzer Laser-Net Fines-C (LNF-C). In the second part of this paper results of measurements are stated. The results are compared and evaluated. Two kinds of fuels was tested - biofuels and traditional fuels. Pure rapeseed methyl ester and various mixtures of traditional diesels and rapeseed methyl ester represented Biofuels. Bioethanol was the next tested biofuels. Traditional diesels were the second group of tested fuels.
