“…The synthesized PI (PMDA-ODA) showed a good extraction performance as the extraction medium for typical volatile organic compounds. The results also suggest that a possibility of the PI to the application as the stationary phase in chromatography, because of a good resistance to typical organic solvents, such as dichloromethane and tetrahydrofuran (THF) along with a good stability at high-temperature conditions typically up to 300ºC [45][46][47].…”

“…There is no significant change was found for the retention factors of all the PACs before and after using pure water as the mobile phase solvent. This is another advantageous feature of the PI stationary phase over typical conventional silica-based stationary phases such as ODS phases [46,12]. As an increased solubility of analytes can be expected at a high column temperature if the mobile phase composition is the same, the excellent resistance to severe separation conditions enables an increased throughput in preparative separations.…”

Spherical polyimide (PI) particles have been introduced as a stationary phase in liquid chromatography (LC). The PI was prepared with the starting materials of pyromellitic dianhydride (PMDA) and 4,4'-diaminodiphenyl ether (4,4'-oxydianiline, ODA), resulting the spherical PI (PMDA-ODA type) particles with an average diameter of about 5 μm. The synthesized PI particles were packed into a conventional blank LC column having a typical size of 4.6 mm i.d, 150 mm length, and the retention behavior for a group of polycyclic aromatic compounds (PACs) was evaluated in LC. The retention behavior was compared with that obtained on a commercially-available octadecylsilica (ODS) phase. The results indicated a significantly larger retentivity of PACs on the PI stationary phase than that on typical ODS stationary phases, where the retention tendency on the PI phase for various PACs having different molecular size and shape was similar to the trend on the ODS phase. The large retention on the PI phase can be interpreted on the basis of the surface structure of the PI particles, because a number of aromatic functionalities are in the chemical structure of the polymer chain backbone.

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.

Simultaneous Derivatization and Extraction of Volatile Amines with Fiber-Packed Needle and Subsequent Analysis in Gas Chromatography

A needle-type sample preparation device packed cyclohexanone-coated fibers as an extraction medium has been developed for the gas chromatographic (GC) analysis of volatile amines in air samples. For a simultaneous derivatization/extraction of monoethanolamine (MEA), a fiber-packed needle was employed, where a bundle of heat resistant filaments, Zylon, poly(p-phenylene-2,6-benzobisoxazole) was packed longitudinally into the specially-designed needle. To the needle-type device, cyclohexanone was loaded in the preconditioning process. Gaseous MEA was sampled by a vacuum air sampler connected to the needle, and a simultaneous derivatization/extraction was carried out therein. Desorption of MEA derivative was successfully made at a heated GC injection port without using any desorption solvent. Introducing the simultaneous derivatization with cyclohexanone, the sensitivity was significantly improved, allowing a more sensitive detection of volatile amines. Taking advantage of the specially-designed needle, the needle was able to be stored for several days at room temperature after the sampling, where the derivatives of the volatile amines were stably trapped on the surface of the Zylon filaments in the needle.
