“…To shorten the time of sol-gel process, a novel organicinorganic hybrid monolithic column for HPLC was synthesized via free radical copolymerization with sonocation assistance by using VTMS and a vinyl ester resin synthesized with methacrylic acid (MAA) and bisphenol A diglycidyl ether as precursors [78]. First, VTMS, PEG (10 000 MW), and acetic acid (0.05 M) were mixed by sonication to form a homogeneous solution at 40ЊC for 20 min.…”

Hybrid organic-silica monolithic columns, regarded as a second generation of silica-based monoliths, have received much interest due to their unique properties over the pure silicabased monoliths. This review mainly focuses on development in the fields of preparation of hybrid monolithic columns in a capillary and their application for CEC and capillary liquid chromatography separation, as well as for sample pretreatment of solid-phase microextraction and immobilized enzyme reactor since July 2010. The preparation approaches are comprehensively summarized with three routes: (i) general sol-gel process using trialkoxysilanes and tetraalkoxysilanes as coprecursors; (ii) "one-pot" process of alkoxysilanes and organic monomers concomitantly proceeding sol-gel chemistry and free radical polymerization; and (iii) other polymerization approaches of organic monomers containing silanes. The modification of hybrid monoliths containing reactive groups to acquire the desired surface functionality is also described.

A hybrid monolithic column with sulfonate functionality was successfully prepared for the simultaneous separation of common inorganic cations in ion-exchange chromatographic mode through a simple and easy single-step preparation method. The strong cation-exchange moieties were provided directly from allylsulfonate, which worked as an organic monomer in the single-step reaction. Inorganic cations (Li(+), Na(+), K(+), NH4(+), Cs(+), Rb(+), Mg(2+), Ca(2+), and Sr(2+)) were separated satisfactorily by using CuSO4 as the eluent with indirect UV detection. The allysulfonate hybrid monolith showed a better performance in terms of speed and pressure drop than the capillary packed column. The number of theoretical plates achieved was 19,017 plates/m (in the case of NH4(+) as the analyte). The relative standard deviations (n = 6) of both retention time and peak height were less than 1.96% for all the analyte cations. The allysulfonate hybrid monolithic column was successfully applied for the rapid and simultaneous separation of inorganic cations in groundwater and the effluent of onsite domestic wastewater treatment system.

“…[1][2][3][4][5][6][7][8] Based on the nature of the matrix chemistry, monolithic columns can be mainly classied into three types: organic polymer-based, 9,10 inorganic silicabased 11 and organic-silica hybrid monolithic columns. [12][13][14][15][16][17] Nowadays, as the newly developed type of monoliths, organicsilica hybrid monolithic columns, which combine the merits of both organic polymer-and silica-based monoliths, have gained great popularity. Surface modication of monolithic columns with different functional groups is a good way to provide a wide range of selectivities for various compounds and has made great progress.…”
