CE, another high performance separation technique, was also proved to be a powerful tool and an alternative for HPLC in the analysis of natural dyestuffs, even if its application in this field is still considerably limited. It could play an important role especially in the analysis of artworks, as it requires a very small volume of a sample solution (a few dozen nanolitres). In CE[ 10 14] separation of charged species is based on their different migration properties along the capillary tube which is in a constant electric field. Two platinum electrodes and both ends of a narrow bore (i.d. 25 100 pm) flexible fused silica capillary (usually 60 100 cm long) filled with a suitable conducting buffer are immersed in two... 

Experimentally, high-performance separations can be performed at lower flow rates using small particle-size stationary phase materials as shown in Figure 1.1. A fast analysis can be achieved at a higher flow rate when the H... 

In the mid 1990s, the first reports on the performance of monolithic columns created much excitement in the scientific community. High-performance separations at low backpressure and a short analysis time were the promise. Nevertheless, it was several years before the first commercial products became available,and made it possible to obtain a proper judgement on the ability and the limitations of the technology. 

Modern HPLC techniques have resulted in a spectacular improvement in speed, resolution, and sensitivity. Separation times in HPLC are usually short, mostly in the interval of 10 - 20 min, with simpler separation problems being carried out in less than 10 min. This is due generally to the use of stationary phase that consists of very small and uniform porous particles with high ligand density. These conditions lead to better mass transfer and higher column efficiency. Consequently, high-performance separations can be obtained in short times (5). 

In contrast to determination of organic analytes, where the use of high-performance separations is almost inevitable in complex matrices, inorganic analysis has powerful tools in highly selective and sensitive spectroscopic methods and thus a sepa-...

The chemical organization (i.e., the primary amino acid sequence) and the folded structure (i.e., the secondary, tertiary, and quaternary structure), including the generation of a surface topography as a discrete three-dimensional object, are the essential features of a polypeptide and protein around which a high-performance separation can be designed. Two sets of factors must come into play for these separation skills to be developed. The first set...

Coupled techniques are a basic tool in inorganic and bioinorganic speciation analysis. Their status results mainly from the possibility of using sensitive and specific detectors, whose advantages can be fully exploited by coupling to high-performance separation techniques, mainly GC, HPLC, CE, and supercritical fluid chromatography (SEC).
