1b. ACI: X-Ray Spectroscopy\Microscopy: ACI: Thermo Scientific, XPS, ESCALAB 250

What is it?
A sensitive technique to investigate elemental composition and associated chemical bonding states of near-surface region of sample.

Manufacturer: Thermo Scientific

Model Name: ESCALAB 250

Applications: Elemental identification except for H. Chemical state identification and quantification. Resolve interfaces and overlapping peaks. Depth profiling and oxide thickness measurements.

Instrument Overview: The sample is prepared and placed in XPS for analysis on elemental composition and chemical bonding states of the surface region. It can be configured with XPS, AES, SEM and UPS features to extract maximum amount of information from analysis.

Technical features and specifications:
High speed acquistion, maximum chemical detectability
1Mcps in normal operating conditions, (0.6eV at FWHM, Ag sample), <3um chemical imaging resolution
95um spot size at 5nA for Auger analysis
Source defined small area from >650um to <120um, lens defined small area down to <20um

Charges: NA
