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.
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.
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 has many uses in everyday life, for example as coolant in cars or in steam irons. It has the reputation of being purer than tap water, which is why distilled water is also used for cleanliness analysis in the laboratory. Residues in the water would contaminate the samples during analysis and distort the results.
