It is often surprising for our customers if we find hard mineral particles on their components during residual dirt analysis. Customers ask: "How can that be? We were not able to determine anything in our own cleanliness tests. ”The question of contamination from 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 have provided us with this interesting sample of volcanic ash, which we examined with our Coxem tabletop SEM-EDX. In addition to the sponge structure of the fine ash particles typical of volcanic eruptions, we identified various microfossils, so-called diatoms.
