[en] The analysis of samples of atmospheric aerosols collected by means of cascade impactores or differential it is facilitated in many aspects by means of the use of technical analytic based on faces of ions. The targets obtained with these apparatuses are those but suitable for their contained first floor of collected matter (1 mg/cm2 what allows the direct use of the samples in technical analytic as PIXE for their high sensibility and in their best interval of applicability. The objective of this work has been the design, construction and the first tests of operation of an impactor of the type Batelle, as well as of another of integral type. (Author)
