  • Plasma treatment-promising tool for preparation of disposable monolithic columns [Elektronski vir]
    Junkar, Ita ...
    Atmospheric pressure plasma jet was employed to improve adhesion between polypropylene (PP) column wall and monolith used in chromatography. Different treatment conditions for modification of PP tube ... were used and the effects of treatment were analysed with X-ray photoelectron spectroscopy (XPS) and atomicforce microscopy (AFM). Modified surfaces had higher oxygen content and surface was covered with small grain like structures. To explore effects of modification on adhesion between PP tube and monolith tensile strength measurements were conducted. It was shown that appropriate treatment conditions significantly increased bonding strength. The improvement of adhesion was attributed to increased oxygen functional groups obtained from plasma.
