| Abstract: | A novel polymer monolithic capillary column functionalized with gold nanoparticles(Au NPs) that enabled the selective capture of thiol-containing compounds was prepared for solid phase microextraction.The column was prepared from a poly(glycidyl methacrylate-co-ethylenedimethacrylate) monolith and has been modified chemically with cysteamine,followed by immobilization of that Au NPs on the surface of the pores of the monolith.Thiol-containing compounds as model compounds were tested to evaluate the performa... |
