Abstract
A combined elevated pressure reactor/ultrahigh vacuum (UHV) surface analytical system has been designed for studies of heterogeneous catalytic reactions. The reaction cell is separated from the surface analysis chamber by a differentially pumped sliding seal. This feature allows simple in situ sample transfer capabilities from the surface analysis region to the reactor cell and also facilitates the introduction and repair of the sample and/or holder with no significant perturbation of the UHV analysis chamber vacuum. The pumping arrangements provide for rapid evacuation of the reaction cell as well as maximum sensitivity with respect to the detection of reaction products.Keywords
