Almost every problem of micromeritics concerns itself with samples Thus, the sample is the first and most important element of micromeritics since the accuracy and precision of the results obtained depend upon the goodness of the sample and how closely it represents the population of which it is a part. It is an important problem of micromeritics to ascertain what sample divider should be used to obtain true informations of given particles.　A new type of sample divider for particles, which applies an uniformity of particle concentration in the fluidized bed, has been originated by us. The structure of this ample divider is shown in Figs 1, 2 and 3. This device has been named ||Jet sample divider|| for particles by us, and its performance tests have been done Consequently, it was found that the ||Jet sample divider|| had the following merits;　(1) it's structure was very simple, furthermore it is easy to operate it and the time reqmred to operate it was less, and　(2) for mixed particles that contain many species of particle having various densities and various size-frequency distribution, the samples divided by this sampling device had approximate attributes of the population.
