“…As an extension of our previous studies, including the employment of natural and synthetic polymers as the stationary phase in chromatographic techniques [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] or the extraction medium in miniaturized sample preparation methods [30][31][32][33][34][35][36][37][38][39], spherical particles of a copolymer material, poly(benzoguanamine-co-formaldehyde) (BF), was introduced as a novel LC stationary phase in this work. The retention behavior for polycyclic aromatic compounds (PACs) on the BF stationary phase was studied on the basis of a systematic comparison with that obtained on a conventional ODS phase.…”

A novel polymer-based particles was introduced as a stationary phase in liquid chromatography (LC). Spherical particles of a copolymer, poly(benzoguanamine-co-formaldehyde) (BF), was packed into a conventional blank LC column and the retention behavior of polycyclic aromatic compounds (PACs) was evaluated in reversed-phase LC. The trend for the retention was compared with that obtained on commercially-available octadecylsilica (ODS) and phenylbutylsilica (PBS) phases. In terms of the trend on the retentivity for PACs, the BF phase showed a similar behavior as that on the ODS phase, although the selectivity to some critical pairs was somewhat different from that on the ODS phase. The results suggest that the BF phase has a retentivity basically on the basis of hydrophobic interaction between the stationary phase ligands and the solute molecule, however, at the same time, the BF phase has a different selectivity from the PBS phase for the recognition of PACs molecules. On the basis of the comparison with the PBS phase, the unique selectivity of the BF phase can be attributed to the restricted moving of the phenyl ligands.

“…Miniaturized sample preparation with fiber-packed capillary and the effective coupling to microscale separation methods will suggest a future possibility to other related applications, such as an interface between two-dimensional chromatographic separations [101][102][103][104][105]. The applications of polymer-coated and surface-derivatized fibrous materials in miniaturized sample preparation process also demonstrate a possibility to the employment of similar fibrous separation media as the new format of the stationary phase materials in various chromatographic techniques.…”

Miniaturization is a key technological approach to realize high performance separation systems that have several important features required in modern analytical methods. A smaller scale of the stationary phase synthesis enables a systematic analysis of the retention behavior and also a more efficient development of novel stationary phases in liquid chromatography. Development of microscale sample preparation technique has been regarded as a valuable supporting approach to the development of microscale separation methods. Effective on-line coupling of the microscale sample preparation and separation allows an efficient and rapid analysis without a loss of sensitivity for most of the analytical separations. In this review, development of the miniaturized separation techniques and the applications have been described from the view point of the authors' research group, including the development of novel stationary phase, microscale sample preparation techniques for liquid and gas sample matrices.

“…The use of the fibrous materials as the stationary phase was investigated in chromatographic techniques including GC [36][37][38][39][40][41][42], capillary electrochromatography [43][44][45] and liquid chromatography [46][47][48][49][50][51][52]. Fiber-packed capillary was also studied as a miniaturized interface between two-dimensional separations [53,54]. Taking advantage of a good heat-resistance, several synthetic polymer filaments have been employed as a stationary phase for high temperature separations in GC, while the sample preparation of liquid samples was carried out with the mini-cartridge packed with a bundle of these filaments.…”

A fine fibrous polyimide (PI) material was introduced as a stationary phase in packed capillary gas chromatography (GC). Packed longitudinally into a capillary, the bundle of the PI filaments exhibited retentivity for a set of test analytes, showing that the PI-packed column was able to work as a stationary phase in GC. On the basis of a systematic consideration of the retention factors for homologous alkanes, it was confirmed that a good linear relationship between the carbon number and the logarithmic retention factor for alkanes at a constant column temperature. Linear van't Hoff plots were also obtained for alkanes, where logarithmic retention factors were plotted against the reciprocal absolute column temperatures. On the basis of the tendency in the retention factors of homologous alkane test analytes, the PI stationary phase has a trend for the retention behavior similar to that of conventional GC stationary phases widely employed, although a certain contribution of polar functional groups in the PI stationary phase to the retention of alcohols was observed. Taking advantage of the good heat-resistance of the PI material, an applicability to temperature-programmed GC separations was also suggested for the fibrous PI stationary phase.
