What are the samples for XPS?
The samples that can be analyzed by XPS are all solids ranging from films, powders to frozen liquids including inorganic compounds, metal alloys, semiconductors, polymers, elements, catalysts, glasses, ceramics, paints, papers, inks, woods, plant parts, makeup, teeth, bones, medical implants, bio-materials, viscous
What is the Beer Lambert law of XPS?
The intensity of photoelectrons emitted at the surface (Is) is determined by the Beer-Lambert Law: Is = Ioe-d/ where Iois the intensity of the photoelectrons emitted at depth d below the surface and is the inelastic mean free path of the electron in the material.

What elements can XPS detect?
XPS Spectroscopy can detect and quantify all elements except for H and He and provide chemical state information, making it a powerful survey analysis technique.
What information can be obtained from XPS?
XPS is routinely used to analyze inorganic compounds, metal alloys, polymers, elements, catalysts, glasses, ceramics, paints, papers, inks, woods, plant parts, make-up, teeth, bones, medical implants, bio-materials, coatings,viscous oils, glues, ion-modified materials and many others.
What are the limitations of XPS?
Because XPS is a surface technique, there is a limited amount of organic information XPS can provide. XPS is limited to measurements of elements having atomic numbers of 3 or greater, making it unable to detect hydrogen or helium. XPS spectra also take a long time to obtain.

What can XPS tell us about a sample?
X-ray photoelectron spectroscopy (XPS), also known as electron spectroscopy for chemical analysis (ESCA), is a technique for analyzing a materials surface chemistry. XPS can measure elemental composition as well as the chemical and electronic state of the atoms within a material.

What is the use of XPS characterization?
XPS is used to characterize the surfaces of diverse materials such as inorganic compounds (minerals), semiconductors, organic compounds, and thin films and coatings on natural and engineered materials.
What information can XPS give you?
XPS is a powerful quantitative technique for determining the electronic structure, elemental composition, and oxidation states of an element in a material.
