Kristina spent some days in the BRAVE lab using their nanoparticle analyzers to investigate the particle size and particle size distribution (PSD) of polymer emulsions. As we are evaluating possible applications of the OF2i technology for online monitoring, there were some fruitful discussions with another visiting scientist Usue Olatz Aspiazu Iturbe (Universidad del País Vasco/Euskal Herriko Unibertsitatea / POLYMAT). Kristina carried out measurements on both the laboratory instrument BRAVE B-Curious and the online sensor BRAVE B-Continuous. The first results are promising and we look forward to gaining deeper insights together.
