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.
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.
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.
The determination of technical cleanliness according to VDA-19.1 and ISO-16232 has become an integral part of quality control and error analysis - because the cleanliness of components is crucial for the quality and error-free functioning of the product. In addition to particles, film contamination is a problem, as the following example from quality assurance in the production of electrical drive systems shows.
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.
In order to answer the question of the whereabouts of microplastic particles from tire abrasion, new analysis methods are urgently needed to reliably detect and count these particles. We conducted a pilot study to test the possibilities of automatic SEM-EDX analysis in the quantification of tire wear in environmental samples.
By popular demand of our customers, we have developed a guide to assist the buyer in choosing a suitable system with practical advice and technical information.
