• High-performance fixed-bed in situ mass analyzer - ISMA 

      Karlsson, Arne; Lødeng, Rune; Haugholt, Karl Henrik; Myhrvold, Elisabeth Meyer; Plassen, Martin (Peer reviewed; Journal article, 2023)
      We demonstrate a newly developed high-performance fixed-bed reactor combined with an in situ mass analyzer (ISMA). The ISMA is particularly relevant to sub-second time-resolved studies where mass changes occur due to, e.g., ...
    • Simultaneous improvement of surface finish and bonding of centrifugal microfluidic devices in cyclo-olefin polymers 

      Vereshchagina, Elizaveta; Andreassen, Erik; Batalden, Jørn; Plassen, Martin; Mielnik, Michal Marek (Chapter, 2018)
      Two key issues in the manufacturing of microfluidic devices are to obtain low surface roughness, i.e. in the range of nanometers (to facilitate optical detection and controlled flow through microfluidic networks), and to ...
