“…22 These solid-phase extractants (sorbents) are typically used by packing into a column or cartridge, which limits the use and application of the particulate sorbent. In addition, the processes involving packing or pulling out the particulate sorbents are complicated 23 because the scattering and adsorption of particulate sorbents occur due to static electricity. Moreover, after packing the particulate sorbents into the column or cartridge, channeling between particulate sorbents may reduce the extraction efficiency in the SPE process.…”

“…Hereafter, the molded particulate sorbent is called an "adsorption medium". Disk-like adsorption media [25][26][27] and porous sintered material 23,28,29 have been reported or are commercially available. However, these adsorption media cannot fully demonstrate the adsorption properties of the included particulate sorbent because the materials used to fasten or bind the particulate sorbent have no or poor adsorption ability.…”

A fabrication method of molding-type solid-phase extraction media (M-SPEM) bound with commercially available adhesive is presented. Six pieces of M-SPEM were prepared by heating each kneaded product of a particulate sorbent and an adhesive inserted into a six-hole cylindrical mold for hardening under an open system and normal pressure. The particulate sorbent contained in M-SPEM was divinylbenzene-based reversed-phase mode solid-phase extractants that we have reported. Examination of several adhesives showed that the moldability of M-SPEM depended on the composition and properties of the adhesive. The optimized procedure can prepare an M-SPEM containing 85 wt% particulate sorbent (particulate sorbent/adhesive=100 mg/17 mg, particle diameter: 90-150 µm), and the M-SPEM has a specific surface area of about 500 m 2 g −1 . The established procedure in this study can bind particulate sorbents together, which showed almost no reductions in the adsorption property and liquid permeability compared with those of the particulate sorbent.

“…[1][2][3][4][5][6][7] A chelating resin immobilizing carboxymethylated polyethyleneimine (CM-PEI), which is commercially available as Presep PolyChelate (FUJIFILM Wako Pure Chemical), has an excellent ability for solid-phase extraction of trace elements. [8][9][10][11][12][13][14][15] This resin is prepared by immobilizing PEI on a porous methacrylate resin (copolymer of glycidyl methacrylate and ethylene glycol dimethacrylate) and then carboxymethylating amino groups in the PEI using sodium monochloroacetate. 8,14 In this resin, the carboxymethylation rate, which is defined as the ratio of the amount of carboxymethyl group (mmol) to the amount of nitrogen (mmol) on the resin, dominates the selectivity of CM-PEI resin for solid-phase extraction of elements.…”

Chelating resins immobilizing carboxymethylated polyethyleneimine (CM-PEI) with different carboxymethylation rates were prepared. The thermal decomposition behavior of CM-PEI resins was investigated using thermogravimetrydifferential thermal analysis/photo ionization-quadrupole mass spectrometry (TG-DTA/PI-QMS) and ion attachment ionization-quadrupole mass spectrometry equipped with direct inlet probe (DIP/IA-QMS). The obtained results suggested that the carboxymethyl group decomposed at relatively low temperature (150 C-300 C); the peak areas at m/z 45 and 59 in TG-DTA/PI-QMS and m/z 58, 70, and 72 in DIP/IA-QMS significantly increased with increasing carboxymethylation rate. These relationships should be useful for estimating the carboxymethylation rate of CM-PEI resin.

“…This procedure of handling a particulate sorbent is sometimes difficult because the sorbents for SPE have small particle diameters and dry conditions, which lead to static cling and scattering. 4 Moreover, the particulate sorbent packed into the cartridge is often uneven and not flat, which causes channeling and/or voiding. Incomplete packing will produce poor repeatability and recovery upon pretreatment.…”

“…5 Monolithic type of sorbents are another solution and can be used for rod, pipette tips or 96-well plates. [6][7][8] Other sintered disk type of sorbents, where there is a mixture of polyethylene powder and ion-exchange resin 9 or chelating resin, 4 have also been reported. These molding types of sorbents are effective for SPE because of their easy handling.…”

Molding-type Solid-phase Extraction Media Glued with Commercially Available Adhesives

In this manuscript, we report a novel molding method of a particulate sorbent for solid-phase extraction (SPE) by using a commercially available adhesive. The handling of the particulate sorbent is generally difficult because it causes the static cling and scattering. To overcome this problem, a simple method for producing a new type of adsorption medium for SPE has been needed. Our developed method can obtain molding media by only mixing the particulate sorbent with commercially available adhesives. Additionally, since these media have a large specific surface area, they can exhibit a higher adsorption capacity than general monolithic media and previously reported mold media. From these reasons, this study has high novelty and is worth being published in Analytical Sciences as Rapid communications.
