Never the less, comparing particle sizedistribution, it was noticed that RF tracer is the most similar to the carrier (Picture 1). Onthe other hand, FS and F tracers have narrow distribution of particle size, as well assmall value of particle number per gram. That is what makes them inappropriate forexamination of premix homogeniety.179
