“…Resulting in higher pressure resistance of the separation system will be required, and this will be a limitating factor in most separation systems. In recent years, monolithic columns have attracted much attention as separation columns due to their high porosity compared to particle-packed columns [8][9][10][11].…”

“…Similarly, silica-based monoliths, which are prepared through the sol-gel method using alkoxysillanes, generally show high mechanical strength and excellent separation performance compared to organic polymer-based monoliths, which are prepared by reacting a solution comprising copolymerized monomer(s), a crosslinking agent, porogen(s) (pore-forming agent), and a polymerization initiator [11,12]. The organic polymer-type monolithic columns are easier to prepare.…”

One-pot Synthesis of Polyethylene glycol-based Polymeric Monolithic Stationary Phases for Capillary Ion Chromatography

Polyethylene glycol-based polymeric monolithic stationary phases (capillary columns of 0.32 mm I.D.) were successfully prepared via one-pot-single-step reaction and were use in ion chromatography for the separation of several common inorganic anions. It should be noted that the prepared polyethylene glycol-monoliths were able to retain and separate the anions even though there were no ion-exchange sites. The retention mechanism was found to be based on the eluent cations trapped among the polyethylene glycol chains and worked as the anion-exchange sites. Several parameters such as the reaction conditions, monomer:porogen ratios, type of eluents, etc., were investigated. The relative standard deviations obtained for the retention times and signal intensities were less than 5 and 10% respectively. Theoretical plate numbers obtained for the separation of these anions were calculated to be in the range of 700-4300 plates for capillary columns of 10 cm in length.

“…Based on the matrix material, chromatographic monoliths are classified as silica or organic monoliths. Silica monoliths have high mechanical strength [2], and organic monoliths can be chemically modified in various ways after preparation [3]. The preparation and characterization of monoliths have been extensively investigated [4,5].…”

Adsorption Isotherms of Hydrophobic Substances onto a Chromatographic Organic Monolith

2015

Adsorption isotherms of hydrophobic substances (methylparaben, coumarin, vanillin, isovanillin, and caffeine) onto a chromatographic organic monolith were measured at 24℃. Adsorption isotherms of coumarin and caffeine were linear and were expressed by the Henry equation. On the other hand, the isotherms of methylparaben, vanillin, and isovanillin were non-linear and could be expressed by combining the Henr y and Langmuir equations. Among the adsorbates having almost the same molecular masses, vanillin was adsorbed the most on the organic monolith, and methylparabene followed. The adsorbate hydrophobicity was not a main parameter reflecting the adsorbability, but any specific interaction between the adsorbate and the monolith would play an important role on the absorbability onto the monolith.
