“…The remainder of our studies therefore involved the use of alternative column housings with more readily modifiable surface chemistry. Although stainless steel tubing is available in a range of geometries and has been used for monoliths before [41], it is not readily functionalised with anchoring groups due to the poor hydrolytic stability of the Me-O-Si-C bonding. Glass-lined steel tubing was considered but not pursued since it is difficult to cut to required lengths without shattering the glass lining; similarly, titanium housings [42,43] were not considered since their use requires a lengthy oxidation step in a furnace (6–8 h).…”

Abstract:The reversed phase liquid chromatographic (RP-HPLC) separation of small molecules using a polystyrene-co-divinylbenzene (PS-co-DVB) polyHIPE stationary phases housed within 1.0 mm i.d. silcosteel columns is presented within this study. A 90% PS-co-DVB polyHIPE was covalently attached to the walls of the column housing by prior wall modification with 3-(trimethoxysilyl) propyl methacrylate and could withstand operating backpressures in excess of 200 bar at a flow rate of 1.2 mL/min. Permeability studies revealed that the monolith swelled slightly in 100% acetonitrile relative to 100% water but could nevertheless be used to separate five alkylbenzenes using a flow rate of 40 µL/min (linear velocity: 0.57 mm/s). Remarkable column-to-column reproducibility is shown with retention factor variation between 2.6% and 6.1% for two separately prepared columns.

“…However, the classical in situ radical polymerization has the disadvantages of slow initiation, fast progression, easy chain transfer, and quick chain termination which lead to a nonuniform structure and then cause low column efficiency, low permeability, and low resolution. To alleviate these disadvantages, atom transfer radical polymerization (ATRP) technique was recently explored as an alternative route for preparation of monolithic stationary phases . ATRP is a commonly used technique for controlled radical polymerization, which employs transition metal complex as the catalyst with an alkyl halide as the initiator.…”

This review article is a continuation of the previous reviews on the area of monolithic columns covering the progress made in the field over the last couple of years from the beginning of the second half of 2014 until the end of the first half of 2016. It summarizes and evaluates the evolvement of both polar and nonpolar organic monolithic columns and their use in hydrophilic interaction LC and CEC and reversed-phase chromatography and RP-CEC. The review article discusses the results reported in a total of 62 references.

“…Triallyl isocyanurate (TAIC) [15] (see Fig. 1 for structure of TAIC) was used as a functional monomer along with trimethylolpropane triacrylate (TMPTA) as the crosslinker to prepare a monolith using atom transfer radical polymerization (ATRP) with CCl 4 as an initiator and FeCl 2 as a catalyst.…”

Recent advances in nonpolar and polar organic monoliths for HPLC and CEC

This article is aimed at providing a review of the progress made in the field over the period 2011 to present in order to expand in parts on two previous reviews (S. Karenga and Z. El Rassi, Electrophoresis, 2011, 32, 90-104; D. Gunasena and Z. El Rassi, Electrophoresis, 2012, 33, 251-261). In brief, this review article describes progress made in nonpolar and polar monoliths used in reversed phase HPLC and CEC (RPC/RP-CEC) and in hydrophilic interaction liquid chromatography/CEC (HILIC/HI-CEC), respectively. This article is by no means an exhaustive review of the literature; it is rather a survey of the recent progress made in the field with 69 references published on nonpolar and polar polymeric monoliths.
