A novel chiral cyclodextrin (CD) monolith was easily prepared via a one-pot process based on the thiol–ene click reaction of allyl-β-CD with pentaerythritol tetra-(3-mercaptopropionate) in a fused-silica capillary.

Octadecyl-functionalized monolithic silica capillary columns with inner diameters of 100 and 200 micrometers for reversed-phase capillary liquid chromatography were prepared in the fused-silica capillary via sol-gel process. Their performance was evaluated and compared by the separation of alkylbenzenes (toluene, ethylbenzene, propylbenzene, butylbenzene). The column back pressure and linear velocity of mobile phase were investigated. The results show that the monolithic silica capillary columns exhibit good performance for the separation of alkylbenzenes.

Off-line supercritical fluid extraction with pure CO2 was used to isolate and quantify bis(2-ethylhexyl) phthalate (DIOP) from PVC samples. Two modes of analyte trapping, onto an inner solid surface of a fused silica capillary (i.d. 0.5 mm) and direct bubbling through a bulk liquid (2-propanol), have been compared. Collected samples were analyzed by high performance liquid chromatography with UV detection. Quantitative recovery of over 95% was obtained in spite of limited operating parameters of home-made SFE device (maximum of pressure 30 MPa and of temperature 70 °C) for samples containing 10 or less wt.% of DIOP.
