Abstract
Synthetic oligonucleotides (ODNs) are routinely analyzed using capillary gel electrophoresis (CGE) for size-sieving based separations as well as electrospray mass spectrometry (ESI-MS) for identification. On-line coupling of these methods is therefore desired in order to combine the analytical capabilities provided by both methods. Performance of on-line CGE-ESI-MS systems is influenced by various parameters, and choice of optimal conditions is crucial for successful coupling experiments. In this study, we explore characteristics of the on-line coupled CGE-ESI-MS system for ODN analysis. Effects of CGE buffer concentration, capillary length, separation and orifice voltage on CGE separation and MS detection of a phosphodiester ODN mixture were examined. Attention was paid to the influence of the interface, such as geometry of capillary alignment, sheath liquid flow-rate and sheath liquid composition on performance of the system.

Abstract
The current status of capillary electrophoresis (CE) in pharmaceutical analyses is reviewed with about 300 references, mainly from 1996 until 1999. This article covers the use of CE for assay and purity determination of the main component, analysis of natural medicines, antisense DNA, peptides, and proteins. Analysis of hydrophobic and/or electrically neutral drugs by electrokinetic chromatography, capillary electrochromatography and nonaqueous CE is critically evaluated. Detailed techniques for the separation of enantiomers are given in the text with some actual applications. Furthermore, this review includes sensitivity and regulatory aspects for the actual use of CE in new drug applications (NDA). The analytical validation required for CE in NDA is also treated.
