      Determination of radium by radon emanation after EDTA-mediated sample dissolution 

      Liatsou, Ioanna; Pashalidis, Ioannis (2015)
      The applicability of radon emanation to determine radium levels in (TE)NORM after EDTA-mediated sample dissolution has been investigated by means of a closed recirculating air loop radon monitoring system. Regarding radium ...

      Facile preparation of polysaccharide-coated capillaries using a room temperature ionic liquid for chiral separations 

      Stavrou, Ioannis J.; Moore, L.; Fernand, V. E.; Kapnissi‐Christodoulou, Constantina P.; Warner, I. M. (2013)
      In this study, the dissolution of polysaccharides into an ionic liquid was investigated and applied as a coating onto the capillary walls of a fused-silica capillary in open-tubular CEC. The coating was evaluated by examining ...

      Sample preparation: A critical step in the analysis of cholesterol oxidation products 

      Georgiou, Christiana A.; Constantinou, Michalis S.; Kapnissi‐Christodoulou, Constantina P. (2014)
      In recent years, cholesterol oxidation products (COPs) have drawn scientific interest, particularly due to their implications on human health. A big number of these compounds have been demonstrated to be cytotoxic, mutagenic, ...
