HPLC-UV-NMR can now be considered to be a routine analytical technique for pharmaceutical mixture analysis and for many studies in the biomedical field. HPLC-UV-NMR-MS is becoming more routine with a considerable number of systems now installed worldwide, but the chromatographic solvent systems are limited to those compatible with both NMR spectroscopy and mass spectrometry. The increased use of HPLC-UV-IR-NMR-MS is possible, but it is unlikely to become widespread, and the solvent problems are more complex. The future holds the promise of new technical advances to improve efficiency, and to enhance routine operation. These approaches include the use of small-scale separations, such as capillary electrochromatography, greater automation, and higher sensitivity and lower NMR detection limits through the use of NMR detectors cooled to cryogenic temperatures. 

Microextractions have the capability to concentrate selectively compounds with particular chemical properties, and to reject solutes with other particular chemical properties. Microextractions function on a small volume scale. As the volumes involved in microextraction and CE can be (but are not necessarily) the same, and given the capability of microextraction to concentrate analytes selectively, microextractions are a natural choice for improving virtually any CE (micellar electrokinetic chromatography, MEKC capillary electrochromatography, CEC etc.) method. 

Separation and mixing of fluids are common operations in chemical and biological assays. When scaled down to microfluidics, these operations are usually achieved by micro pillar arrays. Figure 16 shows an electrochromatography pattern, formed by imprinting a COC...
