Capillary electrophoresis-mass spectrometry (CE-MS) represents a well-established hyphenated analytical technique. It has been successfully applied for many biological, pharmaceutical, environmental, and forensic applications. Among a variety of methods suitable for CE-MS coupling, electrospray ionization (ESI) is the most used. This technique provides a soft ionization of analytes with multiple charges favorable for analyses of macromolecules such as peptides, proteins, and oligosaccharides. Whereas the standard sheath liquid ESI interfaces are commercially available, the potential of nanoESI systems has not been fully explored. Due to ultralow flow rates, typically below 100 nL/min, the nanoESI technology holds a promise of superior ionization
efficiency and reduction of the ion suppression.
