Products for Surface Analysis
Different methods are available for surface analysis.
X-ray Photoelectron Spectroscopy (XPS) also known as Electron Spectroscopy for Chemical Analysis (ESCA) is the most widely used surface analysis technique because it can be applied to a broad range of materials and provides valuable quantitative and chemical state information from the surface of the material being studied. The average depth of analysis for an XPS measurement is approximately 5 nm.
Time-of-Flight Secondary Ion Mass Spectrometry (TOF-SIMS) provides elemental, chemical state, and molecular information from surfaces of solid materials. The average depth of analysis for a TOF-SIMS measurement is approximately 1 nm.
Auger Electron Spectroscopy (AES) provides quantitative elemental and chemical state information from surfaces of solid materials. The average depth of analysis for an AES measurement is approximately 5 nm.
X-ray Photoelectron Spectroscopy (XPS)
The information XPS provides about surface layers or thin film structures is important for many industrial and research applications where surface or thin film composition plays a critical role in performance including: nanomaterials, photovoltaics, catalysis, corrosion, adhesion, electronic devices and packaging, magnetic media, display technology, surface treatments, and thin film coatings used for numerous applications.
XPS is typically accomplished by exciting a samples surface with mono-energetic Al kα x-rays causing photoelectrons to be emitted from the sample surface. An electron energy analyzer is used to measure the energy of the emitted photoelectrons. From the binding energy and intensity of a photoelectron peak, the elemental identity, chemical state, and quantity of a detected element can be determined.

Auger electron spectroscopy (AES)
AES surface analysis equipment provides elemental and in some instances chemical information with the use of a finely focused electron beam to excite the Auger electrons. The analysis of submicron features is routine and thin film analysis is possible with the use of a sputter ion gun to remove material.

X-ray Photoelectron Spectroscopy (XPS) / Hard X-Ray Photoelectron Spectroscopy (HAXPES)
The combination XPS/HAXPES is a laboratory-based instrument used for performing both traditional XPS measurements using an Al Kα X-ray source, plus extended depth of analysis experiments using a Cr Kα (hard) X-ray source. HAXPES using Cr x-rays offers 3× greater depth of analysis compared to conventional XPS.
