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.

“…14,22 Our research group previously developed a purge-and-trap (PT) analysis of VOCs in aqueous samples using a needle-type extraction device. 23 In this study a triple-layer-type extraction needle packed with divinylbenzene (DVB) and activated carbon (AC) particles was used for the extraction of 23 VOCs. The limit of quantifications (LOQs) for the investigated VOCs ranged from 30 to 600 ng L -1 using the total ion monitoring (TIM) mode in GC-MS. 23 For the determination of trace MOCs using this PT method, however, further investigations and improvements are needed.…”

The musty-odor compounds (MOCs) 2-methylisoborneol (2-MIB) and geosmin in water samples were determined by a purge-and-trap method using a needle-type extraction device followed by gas chromatography-mass spectrometry. For the extraction of these compounds, a triple-layer-type extraction needle containing divinylbenzene and activated carbon particles as the particulate extraction media was introduced. Several experimental parameters, including the sample temperature during extraction, the addition of sodium chloride, and desorption conditions, were thoroughly optimized in this study. The detection limits for 2-MIB and geosmin were 1.0 and 0.5 ng L -1 , respectively. The method was successfully applied to the simultaneous determination of MOCs and other volatile organic compounds in tap-water samples.
