Using the Electrochemistry of the Electrospray Ion Source

摘要

ESI MS is one of the more widely used analysis methods, impacting fields as diverse as chemistry, biotechnology, and materials science (i, 2). Even 20 years after ESI burst onto the MS scene, the underlying processes in ESI still continue to be better understood and to provide new opportunities for discovery (3-7). Such is the case for the improved understanding of the electrochemical processes inherent to the operation of this ion source (8-10), which is the topic of this article.
