Sample Environment

Exchangeable Sample Environments allow users to adjust the EnviroESCA machine to different sample and experiment conditions quickly and easily.

KEY FEATURES

• Exchangable Sample Environment
• Quickly adjust conditions to different samples and experiments
• Plasma cleaning mechanism
• Available for different temperature ranges

The stringent UHV requirement of conventional XPS is a limitation that does no longer apply with EnviroESCA. Dedicated sample environment modules are provided as smart units for different classes of samples and applications. The modules are equipped with all relevant components such as sample stage, plasma cleaning and gas handling. Their exchange can be readily accomplished in just a few minutes.

Exchange room temperature (RT) with variable temperature (VT) or high temperature (HT) environments. Use dedicated environments when working performing special experiments using electrical feedthroughs or when working with liquids or messy materials.

APPLICATION NOTES

AP-XPS investigations of a commercial lithium-based electrolyte

In this note we present first AP-XPS results from a commercial liquid electrolyte for lithium ion battery production recorded at 10 mbar in the EnviroESCA. The solution is LiPF6 in EC/DMC as a common battery electrolyte. First we analyzed the LiPF6 solution in its vapor and liquid phase. In a second step we immersed V2O5, a typical cathode material, in this solution. Photoelectron spectra show significant chemical differences on the studied surfaces. This proof of principle study shows the enormous potential of the EnviroESCA for AP-XPS investigations of solid-liquid interfaces and the simplicity of the experimental setup.
