High Resolution Microprobe XPS

Description

The Physical Electronics Instruments (PHI) Quantum 2000 X-Ray Photoelectron Spectrometer (XPS) is a unique Micro-Focused Scanning X-Ray system that uses a focused monochromatic aluminum K X-ray beam that can be varied in size from as small as 10 μm in diameter to approximately 200 μm. The beam can be rastered over larger areas (about 0.5 mm2). The core technology of the Quantera II is PHI’s patented, monochromatic, micro-focused, scanning x-ray source which provides excellent large area and superior micro-area spectroscopy performance. Spectroscopy, depth profiling, and imaging can all be performed over the full range of x-ray beam sizes including the minimum x-ray beam size of less than 7.5 µm. In addition to superior XPS performance characteristics the Quantera II provides two in situ sample parking stations which enables the automated analysis of all three sample platens in a single user defined analysis queue.

XPS is equipped to handle both the standard PHI Quantum 2000 holder and the EMSL sample platens. The standard PHI holder is approximately 3-inch × 3-inch square. Almost any vacuum-compatible sample that fits within the x-y dimensions of the holder and is less than 0.5-inch thick can be analyzed. Samples can be solid or powder, conducting or insulating.
