About The PHI VersaProbe II Scanning X-ray Microprobe system is a state-of-the-art Multi-technique instrument. The system provides X-ray Photoelectron Spectroscopy (XPS) wherein samples are irradiated with monochromatic X-rays, causing photoelectrons to be emitted from a surface of a sample. An electron energy analyzer then determines the binding energy of the photoelectrons which provides elemental, […]
