AbstractA scanning mass spectrometer (SMS) setup was developed allowing for locally resolved probing of the gas phase composition atop planar model catalysts. A thin quartz capillary which connects the reaction room to the analysis chamber equipped with a QMS, enables for sampling of specific regions atop the sample surface using a piezo-driven sample stage. The lower end of the capillary, which extend into the reaction room, either transforms into a very thin tip exhibiting a micrometer sized channel or is equipped with the combination of a flow reducer and an extremely flat titanium cap at the end. Application of the two types of set-ups studying planar model catalysts enable a detailed determination of the spatial distribution of reactant and product gas species atop the sample surface and allow for differential measurement of the product gas evolution when relocating the probe between the catalyst and an appropriate reference sample, respectively.dc.description.abstract
