  • Separation of water-insoluble and neutral linear synthetic polymers in nonaqueous capillary zone electrophoresis using phosphonium-based ionic liquid

    The separation of neutral and water-insoluble linear synthetic polymers in non-aqueous capillary zone electrophoresis using the hydrophobic phosphonium-based ionic liquid trihexyl(tetradecyl)phosphonium chloride (P66614Cl) were investigated using polystyrene, polymethylmethacrylates, polybutadiene, and polycarbonate as test analytes. The solubility of P66614Cl in tetrahydrofuran was above 500 mM, which was significantly higher than that of the general ionic surfactants used in our previous studies. The separation of the four polymers was achieved using a binary mixture of tetrahydrofuran/methanol or tetrahydrofuran/acetonitrile containing P66614Cl as the electrophoretic medium. It was confirmed that an increase in hydrophobicity or bulkiness of the cationic reagent improved the polymer separation. The interaction between polycarbonate with P66614Cl was reduced by the addition of acetonitrile, and enhanced by the methanol addition.

    When a GC/MS system is coupled with a pressurized reactor, the separation efficiency and the retention time are directly affected by the reactor pressure. To keep the GC column flow rate constant irrespective of the reaction pressure, a restrictor capillary tube and an open split interface are attached between the GC injection port and the head of a GC separation column. The capability of the attached modules is demonstrated for the on-line GC/MS analysis of catalytic reaction products of a bio-oil model sample (guaiacol), produced under a pressure of 1 to 3 MPa.

    Plant hormones act as important signaling molecules that regulate responses to abiotic stress as well as plant growth and development. Because their concentrations of hormones control the physiological responses in the target tissue, it is important to know the distributions and concentrations in the tissues. However, it is difficult to determine the hormone concentration on the plant tissue as a result of the limitations of conventional methods. Here, we report the first multi-imaging of two plant hormones, one of cytokinin [i.e., trans-zeatin (tZ)] and abscisic acid (ABA) using a new technology, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI–TOF–MS) imaging. Protonated signals of tZ (m/z 220.1) and ABA (m/z 265.3) were chosen on longitudinal sections of rice roots for MS imaging. tZ was broadly distributed about 40 mm behind the root apex but was barely detectable at the apex, whereas ABA was mainly detected at the root apex. Multi-imaging using MALDI–TOF–MS enabled the visualization of the localization and quantification of plant hormones. Thus, this tool is applicable to a wide range of plant species growing under various environmental conditions.

  • High resolution Kendrick mass defect analysis of poly(ethylene oxide)-based non-ionic surfactants and their degradation products

    Joulnal of Oleo Science ( Japan Oil Chemists' Society )  66 ( 9 ) 1061 - 1072   2017.09  [Refereed]

    Research paper (scientific journal)   Single Author

    Matrix assisted laser desorption ionization (MALDI) high-resolution mass spectrometry (HRMS) and the recently introduced high-resolution Kendrick mass defect (HRKMD) analysis are combined to thoroughly characterize non-ionic surfactants made of a poly(ethylene oxide) (PEO) core capped by esters of fatty acids. A PEO monostearate surfactant is first analyzed as a proof of principle of the HRKMD analysis conducted with a fraction of EO as the base unit (EO/X with X being an integer) in lieu of EO for a regular KMD analysis. Data visualization is greatly enhanced and the distributions detected in the MALDI mass spectrum are assigned to a pristine (H, OH)-PEO as well as mono- and di-esterified PEO chains with palmitate and stearate end-groups in HRKMD plots computed with EO/45. The MALDI-HRMS/HRKMD analysis is then successfully applied to the more complex case of ethoxylated hydrogenated castor oil (EHCO) found to contain a large number of hydrogenated ricinoleate moieties (up to 14) in its HRKMD plot computed with EO/43, departing from the expected triglyceride structure. The exhaustiveness of the MALDI-HRMS/HRKMD strategy is validated by comparing the so-obtained fingerprints with results from alternative techniques (electrospray ionization MS, size exclusion and liquid adsorption chromatography, ion mobility spectrometry). Finally, aged non-ionic surfactants formed upon hydrolytic degradation are analyzed by MALDI-HRMS/HRKMD to easily assign the degradation products and infer the associated degradation routes. In addition to the hydrolysis of the ester groups observed for EHCO, chain scissions and new polar end-groups are observed in the HRKMD plot of PEO monostearate arising from a competitive oxidative ageing.

  • Effect of surfactant species and electrophoretic medium composition on the electrophoretic behavior of neutral and water-insoluble linear synthetic polymers in nonaqueous capillary zone electrophoresis

    Nao Fukai, Shinya Kitagawa, Hajime Ohtani

    We have recently demonstrated the separation of neutral and water-insoluble linear synthetic polymers in nonaqueous capillary zone electrophoresis (NACZE) using a cationic surfactant of cetyltrimethylammonium chloride (CTAC). In this study, eight ionic surfactants were investigated for the separation of four synthetic polymers (polystyrene, polymethylmethacrylates, polybutadiene, and polycarbonate); only three surfactants (CTAC, dimethyldioctadecylammonium bromide, and sodium dodecylsulfate) caused their separation. The order of the interaction between the polymers and the surfactants depended on both the surfactant species and the composition of the electrophoretic medium. Their investigation revealed that the separation is majorly affected by the hydrophobic interactions between the polymers and the ionic surfactants. In addition, the electrophoretic behavior of polycarbonate suggested that electrostatic interaction also affects the selectivity of the polymers.

  • Retention in high-performance liquid chromatography at -196ºC

    Journal of Chromatography A ( Elsevier )  1503   32 - 37   2017.06  [Refereed]

    Recently, we have developed ultralow-temperature high-performance liquid chromatography (HPLC) at −196 °C using liquid nitrogen-based mobile phases. In this study, a retention model for ultralow-temperature HPLC, in which adsorption exchange and “pseudo partition” modes are combined, is proposed to describe the effect of the mobile phase composition on the retention of analytes. The experimental results agreed well with the equation of the proposed model. It was revealed that, in the low and high additive concentration regions, adsorption exchange and pseudo partition retention, respectively, dominate the analyte retention. The difference in the retention behavior between bare-silica and octadecylsilyl-modified silica (ODS) columns was also studied. Retention of alkanes in the ODS column was greater than that in the bare-silica one. Addition of both ethane and ethylene to the mobile phase in the ODS column afforded the elution of propylene, which was not eluted with the bare-silica column at −196 °C.

  • Effect of column structure on separation efficiency in low-temperature HPLC using pure liquid carbon dioxide as the mobile phase

    Research paper (scientific journal)   Multiple Authorship

    The effect of column structure and chromatographic conditions (flow rate, inlet pressure, and temperature) on separation behavior in low-temperature HPLC using pure liquid CO2 mobile phase was investigated. Three types of packed columns (fully porous, small nonporous, and core-shell particles) and a monolithic column (fully porous) were used. The effect of temperature (-5 to -30°C), inlet pressure (5.3 or 6.3 MPa), and flow rate (1 or 2 mm/s) on chromatographic behavior was evaluated. The retention factors of the analytes (naphthalene, anthracene, and pyrene) were not affected by either inlet pressure or flow rate. Although the column temperature somewhat affected the separation efficiency, the typical relationship between temperature and separation efficiency was not observed. On the other hand, both inlet pressure and flow velocity affected the separation efficiency. In this study, the highest separation efficiency was achieved in the core-shell column with a flow rate of 1 mm/s and inlet pressure of 6.3 MPa. The best separation efficiency under this condition was 12 m in theoretical plate height (85 000 N/m) for pyrene at -30°C. In addition, the supplied liquid CO2 was found to solidify in the column at low temperatures and its behavior also depends on both the chromatographic conditions (particularly for flow rate) and the column structure. The typical relationship between solidification and chromatographic behavior was not observed clearly.

  • End group analysis of styrene-butyl acrylate copolymers initiatedwith benzoyl peroxide by stepwise chemolysis-pyrolysis gas chromatography

    End groups in a series of styrene (St)-butyl acrylate (BA) copolymer samples (St:BA, 80:20 molar feed ratio) prepared through radical polymerization with various amounts (1.5–10 wt%) of benzoyl peroxide (BPO) as an initiator were characterized. Two types of end groups originated from the BPO initiator—benzoyloxy and phenyl terminal groups—were individually determined by stepwise chemolysis-pyrolysis gas chromatography (Py-GC) using a double-shot furnace pyrolyzer. In the first (chemolysis) step, the copolymer sample was mixed with tetramethylammonium hydroxide and introduced into the pyrolyzer at 250 °C for 10 min. During this step, the benzoyloxy terminal groups were selectively and quantitatively decomposed into methyl benzoate through the thermally assisted hydrolysis and methylation of ester linkages, which was clearly observed in the pyrogram. In the second step, the residual polymer sample was analyzed by ordinary Py-GC at 600 °C. In the observed pyrogram, benzene and C14H12 were separately detected as the key products reflecting the phenyl terminal groups among the various pyrolyzates of the polymer main chain. Based on the peak intensities of these characteristic products, the relative contents of both types of the end groups from BPO were estimated to be almost proportional to the feed amounts of BPO. Moreover, it was determined that the number of benzoyloxy end groups was roughly twice of that of the phenyl terminal groups.

  • Characterization of the cross-linking structures in UV- and EB-cured acrylic copolymer resins using high resolution MALDI-spiral-TOFMS combined with supercritical methanolysis

    The cross-linking structures of ultraviolet (UV) and electron beam (EB)-cured acrylic copolymer resins prepared with pentaerythritol triacrylate and 1-vinyl-2-pyrrolidone (VP) mixtures were characterized using high resolution matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry (MALDI-TOFMS) combined with supercritical methanolysis. Methyl acrylate (MA)/VP co-oligomers were formed via methanolysis through selective cleavage and methylation at the ester linkages in the radiation-cured resins, which reflected the cross-linking junctions. Almost all of the products were completely separated in the high-resolution spiral TOFMS spectra, including the isotope peaks for a slight mass difference of Δm/z ≃ 0.05. Two types of the copolymeric methanolysis products with different terminal structures were identified for up to 11-mers at approximately m/z 1300 on the MALDI mass spectra. The distributions of the products observed in the mass spectra were interpreted in terms of the original structures of the cured resin samples to reflect the curing reactions.

  • Development of Field-flow Orthogonal Electrochromatography

    A novel separation method that combines liquid chromatography and electrophoresis in a field of heterogeneous flow velocity, named as field-flow orthogonal electrochromatography (FFOEC), is proposed. In the theory of FFOEC, the difference in the orthogonal electrochromatographic migration velocity of analytes in a planer stationary phase with pressurized flow of controlled-heterogeneous velocity can enhance the analytes separation in the flow direction as a similar manner of field-flow fractionation (FFF). Since the essence of FFOEC is a one-directional separation, the parallel detection system is not indispensable, akin to a conventional HPLC, even though a planer stationary phase is used. The polymer monolithic layer with a heterogeneous monolith density to control the flow velocity was prepared using a modulation of irradiation intensity in photo-initiated polymerization. In FFOEC using the heterogeneous density polymer monolith layer, the separation efficiency of the analytes was successfully enhanced with an increase in the applied voltage due to orthogonal electrophoresis.

    Introduction and explanation (others)   Single Author

    Pyrolysis-gas chromatography (Py-GC) was used to evaluate deteriorated acidic paper in old books. A tiny piece (ca. 0.25 mg) of deteriorated paper from each book was subjected to Py-GC measurement at a 300 °C pyrolysis temperature. Levoglucosan and its dehydrated form levoglucosenone were typical degradation products, whereas primarily only levoglucosan was observed in control samples of undamaged new paper. The relative intensity of levoglucosenone was much higher in samples taken at the heavily deteriorated marginal edge than in those taken from the center of the same page of an old book. Accordingly, levoglucosenone observed in the pyrogram can be used as a marker to evaluate the degree of deterioration of acidic paper. The formation of levoglucosenone can be attributed to the slow deterioration process of paper, in which the dehydration reaction plays an important role, accompanied by the chain scission of cellulose. The Py-GC method for paper evaluation was also applied to clarify the effect of storage conditions on the deterioration of paper materials and to evaluate the long-term deterioration of the British Parliamentary Papers (1801–1986) collected at the Kyoto University Library.
