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.
The revised quality standard ISO-16232 “Road vehicles-Cleanliness of components of fluid circuits” was published in December 2018. This international standard for the cleanliness analysis of automotive parts corresponds to the regulations of VDA 19.1, in the development of which RJL Micro & Analytic GmbH played a key role.
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.
A German automobile manufacturer recently learned what problems the smallest residual dirt particles can cause: It had to recall numerous vehicles due to engine malfunctions. The reason was manufacturing residues consisting of hard particles, which lead to major engine damage - in the worst case, to burning cars. Hard residual dirt particles usually come from the fine processing of surfaces by glass blasting, vibratory grinding, honing […]
Bearing shells have the function of rolling and supporting rolling elements. In four-stroke engines, for example, the connecting rod that connects the piston to the crankshaft rotates in a bearing. This is lubricated with oil, which reduces friction and thus wear. However, the lubricant contains various residual contaminant particles that can become lodged in the bearing shell.
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.
