XPS analysis of air-sensitive materials

The nanoFAB is pleased to announce that analysis of air-sensitive materials is available on the PHI VP3 XPS system.

Proper sample handling is critical to analyze materials that are sensitive to air. We have been working to bring the capabilities of analyzing air-sensitive materials on to our analytical instruments. A controlled-environment transfer vessel is now commissioned and available to transfer samples from glove boxes to the PHI VP3 Versa Probe III XPS to minimize environmental exposure during sample transfer/loading.

Comparison of XPS results of a Germanium cluster material that consists of Ge atoms and silyl ligands between (1) using the transfer vessel and (2) short exposure to air, demonstrates the samples are well preserved by the transfer vessel to avoid oxidation.
