Surface-bound organic reactions in organic monolayers can, in principle, be followed by a range of surface-sensitive techniques, including e.g. XPS, contact angle measurements, IR and electrochemistry. An ideal technique would combine robust application, low costs, high throughput rates, high sensitivity, independence of a specific substrate, providing structural and compositional information, and displaying an output that is quantitatively related to the progress of the reaction in an easy fashion. As no technique then combined these features, a few years ago we developed the use of DART ambient mass spectrometry.for this purpose.<br/>The presentation will outline the basis of the technique, an overview with some current examples - including composition of monolayers, rate information on the conversion of one monolayer into another, activation parameters for surface-bound organic reactions, and supramolecular phenomena - and a discussion of the potential of this and related techniques for surface science.<br/>
