In conjunction with the JOMESA optical microscope, the JOMESA PSE provides a fast and cost-effective way of directly supplementing standard analyzes with the further material determination of relevant particles. Based on the results of the optical analysis, the elemental analysis for material determination can be carried out, e.g. of limit-crossing particles. The two microscope systems use a common database, so the coordinates of the relevant particles can be taken directly from the data of the optical analysis for the material analysis.
