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.
A central requirement in the production of pharmaceutical products is the avoidance of visible foreign particles. Our testing laboratory has developed innovative and at the same time simple methods to reliably quantify foreign particles in pharmaceutical powders.
The identification of metallic particles is an important requirement in cleanliness analysis. In recent years, the light-optical detection of metallic particles has commonly been performed by the means of gloss. On the basis of our laboratory experience, we have found that the light microscopic analysis often leads to incorrect typifications, which can be easily avoided by a material analysis using SEM-EDX.
Distilled water finds many uses in everyday life, for example, as cooling water in the car or steam iron. It is reputed to be purer than tap water, which is why it is also used in cleanliness analysis in the laboratory with distilled water. Residues in the water would contaminate the samples during the analysis and falsify the results. Before we distilled water for [...]
