Analysis of Platinum in Ceramics Using EPMA

Analysis of Platinum in Ceramics Using EPMA

Some well-known ceramics are oxides that support a noble metal. While noble metals themselves, particularly platinum (Pt), have low reactivity, they have the property of causing other substances to interact with each other. Due to the low reserves of platinum in the world, measures are being taken to reduce its consumption. This makes it extremely important to produce finer platinum particles and establish an efficient dispersion method for the development of catalysts.

The CeB6-EPMA offers greater sensitivity and higher resolution images than conventional W-EPMA. It permits image observations and element mapping analysis of nano-sized platinum particles in order to evaluate their dispersion.

EPMA-1720 Series Electron Probe Microanalyzers

The electron probe microanalyzer is a non-destructive measurement instrument that irradiates the sample with a finely focused electron beam to reveal the element composition of small areas. It allows the highly sensitive analysis of elements in micron-scale regions on the sample. Simultaneously using submicron-order quantitative analysis and SEM images permits applications to shape inspections. Cause analysis can be performed immediately after foreign matter is discovered.
