*Abstract

At this time the predominant method for a pharmaceutical chemist characterizing reaction kinetics is to employ spectroscopy. The main issue with this technique is that spectrometry produces an absorption/emission spectrum and it is possible for multiple different compounds to have the same spectrum peak making it difficult to differentiate. Time-Resolved Liquid Jet Desorption Electrospray Ionization-Mass Spectrometry (DESI-MS) was developed to collect high time resolution and chemical specificity data in biochemical reactions by providing mass spectrometric analysis. A T mixer allows two separate chemicals in solution to be mixed together to form a free high-speed jet stream. Along the liquid jet, DESI spray ionizes the stream and the resulting ions are then monitored by the MS. The distance the jet travels is indicative of reaction time, so this technology is capable of collecting mass readings at different time points in the reaction.
