摘要： A process of dry dispersal of fine-grained particles on a specimen slide for the purpose of macroscopic or microscopic analysis, and a corresponding instrument for carrying out this process are described. The process permits random, homogeneous distribution of dry particles on a specimen slide in a unilayered, planar distribution, the particles not touching one another at all or only doing so to a negligible extent, i.e. being positioned on the speciment slide without agglomeration. The process steps are: metered input of the fine-grained substance into a sample container; aspiration of the substance by means of a defined partial vacuum, produced in a turbulence chamber, the substance reaching the turbulence chamber via an accelerator tube and then via a distributor tube, and deposition of the accelerated particles on a transparent speciment slide. The device can, in addition, contain a baffle, against which the powder-like sample substance is projected after rushing through the accelerator tube, in order to then pass through a distributor tube, from which the substance falls in deagglomerated form onto the specimen slide. The process and the device can be used for dry dispersal of a great variety of substances in mixed and pure form, for example foods, luxury foods and medicaments or the precursors thereof, mineral or industrial substances, medical or pharmaceutical preparations or precursors thereof, etc. The main area of application is the preparation of powder-like substances for automatic particle analysis.
