    • Determination of steroid hormones in grey seal (Halichoerus grypus) blood plasma using convergence chromatography tandem mass spectrometry 

      Sait, Shannen Thora Lea; Surviliene, Vaida; Jüssi, Mart; Gonzalez, Susana Villa; Ciesielski, Tomasz Maciej; Jenssen, Bjørn Munro; Asimakopoulos, Alexandros (Peer reviewed; Journal article, 2023)
      A hybrid solid phase extraction (HybridSPE) protocol tailored to ultra-performance convergence chromatography tandem mass spectrometry (UPC2-MS/MS) was developed for the determination of 19 steroid hormones in grey seal ...

    • Oxidative degradation of triethylene glycol 

      Høisæter, Karen Karolina; Buvik, Vanja; Gonzalez, Susana Villa; Vevelstad, Solrun Johanne; Knuutila, Hanna Katariina (Peer reviewed; Journal article, 2024)
      Triethylene glycol (TEG) is unstable in the presence of oxygen and at high temperatures, though the degradation mechanisms occurring are not properly understood. In attempting to close some of the knowledge gaps, ...
