Coupling electrochemistry and desorption electrospray ionization mass spectrometry to observe transient electrochemical intermediates
Abstract/Contents
- Abstract
- The observation of electrochemical reaction species directly after electrochemical generation has been a goal of electrochemists for years, and is a problem that has been approached using many different analytical techniques. The challenge in acquiring faster response times exists in transferring electrochemically generated species quickly from solution to the gas phase for MS detection. The development of DESI allows for analyses to be made on surfaces under atmospheric pressure and at room temperature with a sampling time on the order of milliseconds. In collaboration with Prof. Hao Chen, we present a new DESI-ECMS technique for the mass spectrometric detection of fleeting reaction intermediates in electrochemical reactions utilizing a "waterwheel" working electrode setup is presented here. This setup takes inspiration from DESI-MS to sample directly from the surface of a working electrode for in situ electrochemical mass spectrometric analysis in seeking shorter analysis timescales. A number of systems is presented here verifying the viability of the waterwheel for DESI-ECMS analysis to observe fleeting electrochemical intermediates.
