摘要：
The effect of the electrospray ionization (ESI) needle voltage on the electroosmotic flow (EOF) in capillary electrophoresis (CE)-mass spectrometry (MS) was investigated. The radial electric field that penetrates across the CE capillary wall imposed by the ESI-needle voltage modifies the typical EOF. This effect was investigated for buffers commonly used in CE-MS. Variations as high as -/+30% were observed. (C) 1999 American Society for Mass Spectrometry.
