“…[23][24][25] In those studies, even if the retentivities to homologous analytes were different, a general trend in the selectivity between these analytes could be similar, suggesting the existence of an optimum combination of the type of polymeric coating and the fibrous material. 25,39 Based on a successful polymeric coating on the surface of Zylon fiber, confirmed as the increased retentivity to two typical non-polar analytes in Table 1, the HR-17 coating was chosen as the main coating material in following experiments.…”

Novel polymer-coated fiber-packed microcolumns in liquid chromatography (LC) have been developed. Typical polymeric materials, such as polydimethylsiloxane and polyethyleneglycol, which are conventional stationary phases of capillary columns in gas chromatography (GC), have been employed as coating materials onto the surface of fine filaments. Packed longitudinally with a bundle of polymer-coated filaments into a stainless-steel capillary of 0.8 mm i.d., 150 mm length, several types of polymer-coated fiber-packed columns were prepared, and the retention behavior of aromatic compounds on these columns has been studied. A good linear relationship was obtained for van't Hoff plots over the temperature range between 0 and 200 C, clearly indicating an excellent heat-resistant property of these polymer-coated fibrous stationary phases. Taking advantage of the heat-resistant feature of the fibrous stationary phases, the separation of several test mixtures with temperature-programmed elution was studied, where a solvent gradient program was additionally introduced if needed. Separation was also carried out with pure water as the mobile phase using an appropriate temperature program.

“…Alternative sample preparation techniques have been developed as a needle-type sample preparation device. [7][8][9][10][11][12][13][14][15] Compared to the conventional SPME, the needle-type sampling device has been regarded to have good mechanical strength and high extraction capacity. In our previous work, a polymer particulate medium based on a copolymer of methacrylic acid (MA) and ethylene glycol dimethacrylate (EDMA) was synthesized, and packed into a specially-designed needle as the extraction medium.…”

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.
