Colorblindness has long been touted as an advantage of electron beam and a key differentiator between EB and UV technologies. And it’s true, the penetration of UV light is dependent on the optical clarity of the material it’s interacting with, while EB penetration is governed by material density (and chemical composition) – i.e., zip, zero, nada to do with color, opacity or any … [Read more...] about Colorblind EB

Incorporation of Carbon Nanotubes into UV-Polymerizable Formulations, Part 2
In the last issue of UV+EB Technology, we began a discussion about the preparation of nanocomposites made by incorporating carbon nanotubes into UV-polymerizable formulations. 1 That article covered the experimental techniques used by students at the University of Houston-Downtown 2 to determine how well single-walled carbon nanotubes (SWNTs) were dispersed (exfoliated) in an … [Read more...] about Incorporation of Carbon Nanotubes into UV-Polymerizable Formulations, Part 2
Electron Beam Dosimetry
Dose is a crucial variable in any electron beam (EB) application, and it is equally important to be able to measure and verify that dose. 1 Just as the output of UV lamps can be monitored by a radiometer, dosimetry can be used to monitor EB dose. From setting up a new beam to exploring new applications, during troubleshooting and after routine maintenance, dosimetry is an … [Read more...] about Electron Beam Dosimetry
UV LED Measurement: Keys to Success
Inspiration for this column came while visiting friends in Florida. It hit not while soaking up UV photons at the pool, but when helping mount two TVs and speaker bars. Once we found the wall studs, mounting the TVs was straightforward. We creatively overcame the missing hardware for the speaker bars with a trip to the hardware store. Extra time was spent gathering tools from … [Read more...] about UV LED Measurement: Keys to Success
Profilers: Radiometers with Benefits
Imagine if a UV process generated a dating profile looking for a radiometer: UV process ISO of a committed, stable, long-term, quality relationship. Prefer a consistent and controlling partner that can point out changes, flaws and/or tell me when I need to change. Need to have a quick response and be good with numbers. Forget long walks on the beach! I want long periods of … [Read more...] about Profilers: Radiometers with Benefits
