This review provides an update on the implementation of emerging materials as sorbents for sample preparation in combination with chromatographic separation. We have focused on recent applications of metal-organic frameworks, layered double hydroxides, porous carbons obtained from polymers or biomass precursors, and silicates (clays and zeolites). The review is directed toward the strategies followed by the authors to engineer suitable supports enabling the application of materials with unconventional size and shape as high-performance sorbents to explore new boundaries in sample pretreatment in manual or automated modes.

“…On the other hand, liquid chromatography usually aims at the separation of a group of analytes from each other and from the sample matrix. In this sense, these techniques are complementary and hyphenation can synergistically improve the overall performance including, for instance, in-line sample treatment (clean-up or analyte concentration) in a flow system previously to chromatographic separation (Brunetto et al 2015, Ghani et al 2016a). Chromatographic separations have been incorporated to flow analysis by using short (monolithic or fused-core) columns able to operate at relatively low pressures.…”

Coupling solid-phase extraction (SPE) to flow systems has promoted a synergistic development. Whereas SPE mechanization leads to improved precision and higher sample throughput, as well as diminishes systematic errors and contamination risks, analyte concentration and separation from the sample matrix provides a remarkable impact on detectability and selectivity in flow analysis. Historical aspects, main cornerstones, tips for system design, and recent applications are critically reviewed, in the context of analyte(s) separation/concentration, sample clean-up, and release of sorbed chemical species involving both packed (e.g. mini-columns, cartridges, and disks) or fluidized (e.g. beads and magnetic materials) particles. Novel (bio)sorbents, selective synthetic materials, and stationary phases for low-pressure chromatography are also discussed. Moreover, the feasibility of SPE for sample treatment before chromatographic separation, as well as the exploitation of direct measurements on the solid phase (optosensing) are emphasized.

“…MF resin, a thermosetting resin with features of high nitrogen content, flame retardance, and heat resistance, has wide potential applications, such as flame retardant, heat insulation, battery separator, supercapacitor, ion removal, and absorbents . Based on their spatial dimensions, multifunctional materials containing MF resin are mainly divided into four categories: micro‐ and nanospheres (zero‐dimensional), fibers (one‐dimensional), mats (two‐dimensional), and foam (three‐dimensional). In the four categories, melamine fiber, especially microfiber, has relatively been less studied.…”

Melamine microfibers were first prepared by centrifugal spinning. The stability and spinnability of a melamine-formaldehyde (MF) resin solution were improved as expected by adding various modifier combinations. Considering the storage stability of solutions characterized by visual inspection, turbidity tests, and viscosity measurements and combined with the fiber morphology, the optimal modifier combination was obtained. The spun fibers manifested a good morphology and thermal stability as measured by scanning electron microscopy, Fourier transform infrared spectroscopy, and thermogravimetric analysis. Moreover, microfibers prepared by three spinning methods (centrifugal spinning, electrospinning, and centrifugal electrostatic spinning) were compared to choose the suitable spinning method for different fields in the future. This work provides systematic and scientific guidance on the synthesis of MF resin solutions and rapid mass production of melamine microfibers and also demonstrates that centrifugal spinning of melamine microfiber is a promising candidate for flame retardance and CO 2 adsorption at elevated temperature.
