High-Sensitivity Analysis from Small to Large Areas

High-Sensitivity/Low Noise Newly Designed Analyzer

XPS is used to study the elemental and chemical composition state of solid surfaces such as battery materials, catalysts, electronic circuit boards, organic semiconductors, metals, polymers, ceramics and glass to meet a wide range of analytical requirements from R&D to failure analysis.
VersaProbe 4 is more than twice as sensitive as our previous model, with significantly higher lower detection limits and the ability to perform highly sensitive analysis from very small areas (1 mm).
Our unique micro focus scanning X-rays and scanning X-ray induced secondary electron images (SXI) allow SEM-like sample to navigate the sample and define analysis location with 100% certainty.

The Ultimate in Depth Profiling

Accurate Depth Profiling using Micro-XPS Analysis Technology

The VersaProbe 4's high-sensitivity microanalysis and highly reproducible neutralization performance are outstanding in depth profiling. The combination of sample tilt and sample rotation allows for high depth resolution and high energy accuracy at the same time.

Unique Automated Charge Neutralization

Charge Neutralization with No Adjustments Required for Microanalysis of Insulators

VersaProbe 4 uses automated charge neutralization, which eliminates the need to make adjustments for each sample to be measured. Automated neutralization uses unique charge neutralization technology combining a low-energy electron beam and an ion beam for efficient neutralization.
It can be adapted to neutralize a wide range of materials and provides unparalleled automated operation for micro-analysis by using an image registration function. Automated and reliable measurements are possible for mixed inorganic/organic materials, and for all analysis area sizes - small or large.

Automation and Remote Access Provide a Flexible Working Environment

Remote Access Allows Remote Control of the Instrument

VersaProbe 4 allows access to the instrument via the company’s local area network or the internet.
Once a sample has been introduced into the analysis chamber, it is possible to navigate the sample using intro photos and SXI, create automated queue of acquisition tasks, check the measurement status, and analyze the data remotely. The instrument can also be remotely diagnosed by our expert staff.
