SCALING BULK TO NANO Create the most relevant and realistic environments for the studies of catalytic activation, operation, and degradation Patented volumetric blending system is calibration-free and accurately handles complex and custom gas mixtures Mimic an environment’s moisture levels by creating humidity at room temperature, preventing condensation within the system Non-metallic heating element heats up to 1000 ºC without contributing artifacts to the reaction

Humidity can have a detrimental effect on catalyst activity. Here, MgO crystals are exposed to a humid environment in the TEM and form Mg(OH)2 on the surface at 250°C, but the reaction is slowed at 700°C. Mass spec data confirms the presence of water vapor in both instances.

High-entropy-alloy (HEA) nanoparticles can be used in a variety of applications in catalysis and electrocatalysis. In situ STEM analysis revealed that the porosity of the particles was maintained up to 800 °C. De Marco, M. L. et al. (2022) ACS Nano, 16, 15837-15849

Integrated residual gas analyzer (RGA) mass spectrometer is the first of its kind for TEM, with ultra-quiet operation that allows use without loss of image resolution

The Atmosphere AX’s integrated RGA enabled researchers to measure the gas production of Fischer-Tropsch catalysts (cobalt platinum) on different support materials (silicon oxide [top] and aluminum oxide [bottom]) under in a syngas environment.

Dembélé, K. et al. (2021) ChemCatChem, 13, 1920–1930

The unique design of the integrated RGA removes the need for a noisy roughing pump and can then be mounted close to the reaction in the TEM for fast gas detection and easier alignment of images with mass spec data.
