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.
Scanning electron microscopy
Employees from the wood engineering department sent us an aged wood sample with a typical discoloration. With our Coxem scanning electron microscope we have imaged the microstructure in high resolution and carried out an elemental analysis of the discoloration.
When it comes to component cleanliness, the toughest particles cause the greatest damage. The difficulty, however, is to find these killer particles because they can be so small that they can not be seen with a light microscope.
The Korean company Coxem has developed economical desktop devices for the SEM-EDX analysis, which convince with an outstanding resolution. This new product series is now also available in Germany via RJL Micro & Analytic. Customers benefit from our proven support and technical service. Superior electron optics A newly developed electron optics achieves a resolution of 5 nanometers and thus [...]
Which problems smallest remainder dirt particles can cause, has recently experienced a German car manufacturer: He had to recall numerous vehicles due to malfunction in the engine. Reason were production residues consisting of hard particles, which lead to a capital engine damage - in the worst case to burning cars. Hard residual dirt particles usually come from the fine machining of surfaces by glass blasting, vibratory grinding, honing [...]
Bearing shells have the function to unroll and support rolling elements. In four-stroke engines, for example, the connecting rod, which connects the piston to the crankshaft, rotates in a bearing. This is lubricated with oil, which reduces the friction and thus wear. In the lubricant, however, various residual dirt particles are contained, which can settle in the bearing shell. In the past, the [...]
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 [...]
