We recently determined for an analytical client whether and to what extent the rubber stopper used to seal a medication bottle generates particles when pierced with a syringe to withdraw the medication. The client was surprised that piercing the stopper can generate particles measuring several hundred micrometers and wanted to statistically investigate the process.
Anyone who has samples tested for cleanliness relies on reliable testing and precise determination and representation of the particles contained. With our Particle Browser, we offer you software for follow-up checks and revisions to verify analysis results and to identify and correct possible measurement errors.
Coxem has introduced a new model of its compact ion mill CP-8000+. The device supports the standard cutting (“cross-sectioning”) and polishing (“flat milling”) modalities and can be operated intuitively via the integrated touchscreen.
A year and a half ago we installed a Coxem EM-30N at the Eberswalde University for Sustainable Development (HNEE). This mosaic shows a 3-point bending fracture in a deformed wood sample. With the standard integrated panorama module from Coxem, 169 individual images of a microtome section of the fracture site were collected at 200x magnification with the secondary electron detector and automatically stitched.
We supported Bruker Nano in the world's first commissioning of a compact EBSD system on our Coxem Tabletop SEM-EDX. The installation went smoothly and after one hour we were able to record the first EBSD mappings ‒ Important step for the market introduction of the EBSD technology for SEM-EDX tabletop devices.
Coxem recently presented a new backscattered electron detector (BE) for their 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.
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 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.
Researchers from Bremen provided us with this interesting sample of volcanic ash, which we analyzed with our Coxem Tabletop SEM-EDX. In addition to the spongy structure of the fine ash particles typical of volcanic eruptions, we identified various microfossils, so-called diatoms.
