SPECTROSCOPY FEATURES
UV-VIS Spectroscopy Extends from the Lab to Outer Space May 27, 2021 — UV-VIS spectroscopy has been a robust spectroscopic modality since at least the early 1940s. That’s when National Technical Laboratories (now Beckman Coulter) released its DU spectrophotometer — one of the first widely available, tabletop-size UV-VIS instruments. Although many scientists and engineers have preferred other spectroscopic methods as light source and detector technologies have advanced, the use of UV-VIS spectroscopy has not dwindled. In fact, growth in the pharmaceutical, food,...
