Temporal analysis of products

Temporal Analysis of Products (TAP), (TAP-2), (TAP-3) is an experimental technique for studyingthe kinetics of physico-chemical interactions between gases and complex solid materials, primarily heterogeneous catalysts. The TAP methodology is based on short pulse-response experiments at low background pressure (10−6-102 Pa), which are used to probe different steps in a catalytic process on the surface of a porous material including diffusion, adsorption, surface reactions, and desorption.

Since its invention by Dr. John T. Gleaves (then at Monsanto Company) in late 1980's, TAP has been used to study a variety of industrially and academically relevant catalytic reactions, bridging the gap between surface scienceexperiments and applied catalysis. The state-of-the-art TAP installations (TAP-3) do not only provide better signal-to-noise ratio than the first generation TAP machines (TAP-1),but also allow for advanced automation and direct coupling with other techniques.
