“…These studies are currently underway in our laboratory including the interpretation of the retention mechanism on the basis of a molecular simulation [46][47][48]. Tanking into account a good heat resistance of the BF phase up to 300ºC and a good solvent resistance, the possibilities of the BF phase to the materials as the stationary phase in gas chromatography [49,50] and the extraction medium in sample preparation [51,52] are also investigated.…”

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.

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.

“…In packed-column GC, a wide variety of stationary phases can be employed [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] including fine polymeric fibers having a good heat-resistance [13][14][15][16][17][18][19][20][21][22][23][24][25], and therefore, various types of volatile compounds having different polarities as well as permanent gases were successfully separated with a reasonable analysis time [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. The sample loading capacity of the packed-column is also quite remarkable.…”

Determination of coumarin in kerosene was studied. Kerosene is discriminated from taxed fuel oil by the addition of coumarin in Japan. A fluorescence detection method has been widely used to check the legal distribution of kerosene, however, the method is inevitably resulting waste fluid consisted both of the aqueous alkaline solution and the organic solvent. By introducing a heart-cutting analysis with a set of on-line coupled packed-capillary and open-tubular columns, coumarin in kerosene was successfully determined in gas chromatography. The developed technique showed several advantageous features such as a significantly reduced waste, quick and easy separation/determination, along with a reduced sample volume required in the determination process.
