“…However, no quantitative relationships were given. Furthermore, novel packing techniques -applying continuous vibration of the stationary phase slurry suspension with the aid of an ultra-sonification probe -do not seem to produce significantly better columns in terms of efficiency and column lifetime [91 ].…”

This review discusses many different aspects of microcolumn liquid chromatography (LC) and reflects the areas of microcolumn LC research interest over the past decades. A brief theoretical discussion on a number of major issues, such as column characterisation, chromatographic dilution effects and extracolumn band broadening in microcolumn LC is given. Recent progress in column technology and the demands and developments of instrumentation and accessories for microcolumn LC are also reviewed. Besides that, the developments in a large number of established and also more recent detection techniques for microcolumn LC are also discussed. The potential of hyphenation of microcolumn LC with other techniques, more particularly of multidimensional chromatography and microcolumn LC coupled to mass spectrometry is reviewed. Finally, the perspective of microcolumn LC separation methods is stressed by a number of relevant applications.

“…There is, however, a tendency to use columns with an even smaller I.D. Driving forces towards this even further miniaturization are the use of such columns in capillary electrochromatography (CEC) [91][92][93] and electrospray ionization-mass spectrometry (ESI-MS). In CEC, columns with an I.D.…”

“…First the system should be handled in such a way that it prevents bubble formation within the sorbent bead. This could be prevented either by pressurizing the vials to about 500 psi or by using low conductivity buffers like Tris and MES [60,61]. If such precautions are not taken it is difficult to use buffers of higher 21 concentration than 10 mmol l because degassing at high currents distorts both the detection and the very separation.…”

This review summarizes the advancement in operational modes and selected applications of the title technique over the past five years. Regarding operational modes particular emphasis is put upon increasing selectivity and resolution, hyphenation of capillary electrophoresis with techniques based on other than electromigration principles, the so-called chip technology and new ways of detection. In applications selected examples of chiral separations and separation of biopolymers (proteins, nucleic acids) are emphasized. It is demonstrated that capillary electrophoresis represents a complementary technique to high-performance column chromatography and in a number of cases it offers better separations than standard chromatographic procedures.
