9:00-10:30 Dr. R. Horn  (FHI-AC) Chemical (Elemental) Analysis
The activity of a heterogeneous catalyst is closely related to its chemical (elemental) composition. Therefore, the chemical analysis of a catalyst at different points in his life (freshly prepared, calcined, activated, deactivated) supplies valuable information why a catalyst is active or why not. There are a wide variety of analytical methods available to determine quantitatively the composition of inorganic materials. The talk presents the most important of these methods (volumetry, gravimetry, potentiometry, polarography, AES, AAS, ICP-MS, XRF, SEM/EDX, XPS) that can be used for an elemental analysis ranging from concentrations in the percent range to traces and ultra traces. Besides presenting instrumentation and analytical performance of the different methods, the talk covers fundamental analytical concepts like detection limit, quantification limit, selectivity, accuracy, precision etc. and presents some elementary statistical tools to specify an analytical result correctly.
10:45-12:15 Dr. W. Ranke  (FHI-AC) Auger Electron Spectroscopy and Other Modulation Techniques
Auger electron spectroscopy (AES) as a standard method for the determination of the elemental composition of a surface will be presented. AES belongs to the class of modulation techniques using Lock-In amplifiers. The principle of these techniques will be sketched.

Can we believe in the incredibly accurate indications of digital displays of modern instruments for T- and p-measurement? Which physical effects are used? What can we do to be reasonably sure that the measured values really represent those of the sample?
