“…The fibrous materials could be further applied to microscale sample preparation as the extraction media. More extensive studies, including more precise control of the column temperature, theoretical prediction of the retention during temperature-programmed elution, 14,46 and the development of other polymer-coated fiber-packed materials, [47][48][49] are currently being investigated in our laboratory, including the employment of these fibrous materials as an extraction medium in a miniaturized sample preparation technique.…”

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.

“…In-needle derivatization methods were developed for several target analytes with a fiber-packed needle. Because of the inert surface of the fibers, the derivatization reaction in the needle was successfully processed, where the change of the chemical structure of the target analytes during the derivatization reaction make it possible for the derivatives to be extracted more effectively in the needle extraction device [79][80][81][82].…”

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.

“…packed needle was also employed for the determination of bisphenol A in water samples using the derivatization reaction with N,O-bis(trimethylsilyl)trifluoroacetamide (BSTFA). 61 After the extraction of bisphenol A onto the polymer-coated fiber by pumping aqueous solution into the needle, the remaining water in the needle was completely eliminated by N2 gas flow, aspiration by a vacuum pump, and heating. Then, BSTFA was introduced into the needle, and reacted with the analyte by heating.…”
