High-performance X-ray source

The X-ray monochromator allows selection of analysis area from 50 µm to 400 µm in 5 µm steps, fitting it to the feature of interest to maximize the signal.

Optimized electron optics

The high-efficiency electron lens, hemispherical analyzer, and detector allow for superb detectability and rapid data acquisition.

Sample viewing

Bring sample features into focus with the K-Alpha XPS System’s patented optical viewing system and XPS SnapMap,

Insulator analysis

The patented dual-beam flood source couples low-energy ion beams with very low energy electrons (less than 1 eV) to prevent sample charging during analysis, which eliminates the need, in most cases, for charge referencing.

Depth profiling

Go beyond the surface with the EX06 ion source. Automated source optimization and gas handling ensure excellent performance and experimental reproducibility.

Digital Control

Intuitive operation—guided by the Avantage data system—makes the K-Alpha XPS System ideal for both multi-user, shared facilities and XPS experts who place a premium on efficient operation and high-throughput analysis.

Optional sample holders

Specialist sample holders for angle-resolved XPS, sample bias measurements, or for inert transfer from a glove box are available.
