The determination of the technical cleanliness according to VDA-19.1 or ISO-16232 is now an integral part of quality control and error analysis - because the cleanliness of components is decisive for the quality and error-free function of the product. In addition to particles, filmic contamination poses a problem, as the following example from quality assurance in the manufacture of electric drive systems shows.
In order to answer the question of the whereabouts of microplastic particles from tire abrasion, new analysis methods are urgently needed to reliably identify and count these particles. We conducted a pilot study to test the possibilities of automated SEM-EDX analysis in quantifying tire abrasion in environmental samples.
Since the beginning of this year, Heilbronn University has had a MicroQuick particle scanner from RJL Micro & Analytic GmbH. Mrs. Prof. Dr. Katja Mannschreck from the Process and Environmental Engineering course and her students have already successfully used the particle scanner in a number of projects.
A central requirement in the production of pharmaceutical products is the avoidance of visible foreign particles. Our testing laboratory has developed innovative yet simple methods to reliably quantify foreign particles in pharmaceutical powders.
