We recently supported Bruker Nano with the world's first commissioning of a compact EBSD system on our Coxem Tabletop SEM-EDX. Thanks to good preparation, the installation went smoothly and after just one hour we were able to record the first EBSD mappings. For Bruker and Coxem, this test represents an important step towards commercializing EBSD technology for SEM-EDX desktop devices.
Coxem recently presented a new backscattered electron detector (BE) for its SEM-EDX systems, which impresses with its excellent sensitivity. The new BE detector is particularly interesting for applications that benefit from a high contrast of the atomic number Z.
In its recent issue from April 28th, 2020, the Badische Neusten Nachrichten (BNN) published an article very much worth reading about our involvement in the development of a procedure for the refurbishment of medical protective masks.
Given the continuing shortage of protection materials for hospital staff during the Corona crisis, Helios experts have in the past weeks developed a safe procedure for refurbishing FFP masks. Helios is making this method publically available, so that all medical staff can be supplied with sufficient protective materials.
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.
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 at 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 [...]
