Excellent performance, delivering high quality spectra in seconds.

The Thermo Scientific ESCALAB Xi+ XPS (X-ray Photoelectron Spectrometer) microprobe is a multi-technique surface analysis system for high-resolution XPS spectroscopy and imaging.
Excellent performance, delivering high quality spectra in seconds.
Including ISS and REELS as standard.
In-situ heating and cooling, fracture stage and inert transfer.
The Thermo Scientific ESCALAB Xi+ X-ray XPS combines high spectral sensitivity and resolution with high-resolution quantitative imaging and multi-technique capabilities.
For small-area spectroscopy, the ESCALAB uses three methods to define the analysis area:
An electron source, co-axial with the analyzer input lens, is used for charge compensation when analysing non-conducting samples with the monochromatic X-ray source. A second flood source provides both low-energy ions for effective charge compensation and low-energy electrons while the magnetic lens is not being used.
The lens and analyser system is optimised for spectroscopy and parallel imaging. The single analyser path means that the same instrument parameters (eg pass energy) can be used for both spectroscopy and imaging.
There are two detector systems:
There are two options for fast, high-resolution depth profiling:
All analytical functions are controlled using Thermo’s Windows-based Avantage software, so analysis can be performed remotely if necessary.
A standards block with copper, silver and gold samples is used to check sensitivity, set the linearity of the analyser energy scale, calibrate the ion source, align the X-ray monochromator, and determine the transmission function of the analyser.
Sample stage movement is controlled by the software. A high-resolution digital video camera provides a view aligned exactly with the analysis position.
The standard Preploc chamber is a combined sample entry lock and preparation chamber. There are ports for a range of devices including heating/cooling probes, ion guns, high-pressure gas cells, sample parking and gas admission.
