It is often surprising for our customers when we find hard mineral particles on their components during technical cleanliness analysis. Customers ask: "How can that be? We didn't find anything in our own cleanliness tests." The contamination of hard minerals is so important, because these particles have an abrasive effect and thus massively damage mechanical systems such as gears and motors.
Researchers from Bremen provided us with this interesting sample of volcanic ash, which we analyzed with our Coxem Tabletop SEM-EDX. In addition to the spongy structure of the fine ash particles typical of volcanic eruptions, we identified various microfossils, so-called diatoms.
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.
Employees from the wood engineering department (Abteilung Holzingenieurwesen) sent us an aged wood sample with a typical discoloration. Using our Coxem scanning electron microscope, we imaged the microstructure in high resolution and performed an elemental analysis of the discoloration.
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.
The RJL Micro & Analytic team wishes you and your families a Merry Christmas and a healthy 2020. Please note that our test laboratory will be closed from December 24th, 2019 to January 6th, 2020 and our secretariat will only be available to a limited extent during this time. [...]
For the latest generation of SkyScan micro-CT devices, Bruker has developed a special scan mode for samples with a high aspect ratio. Objects of this type are characterized by a high ratio of length to width and repeatedly pose challenges for users of microtomography.
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.
In response to many requests from our customers, we have developed a guide to help buyers choose a suitable system with practical advice and technical information.
