Finally, properties such as adhesion, wetting, and heterogeneous catalysis are strongly governed by the identities and the oxidation states and the bonding of those atoms in the surface layer, or the.

Our webinars provide insightful information and innovative approaches to microanalysis that apply to a wide range of industries.

In order to predict how a material will reactor understand how it has reactedto a given chemical environment, surface-sensitive analytical techniques must be utilized.

One such technique is X-ray photoelectron spectroscopy (XPS), also known as electron spectroscopy for chemical analysis (ESCA).

XPS exploits the nanometer-scale path length of electron photemission in solids to reveal information about a samples surface composition and chemistry.

This free webinar provides a brief overview of the underlying theory of XPS, and demonstrates a variety of XPS analysis techniques that can be performed, including compositional depth profiling and chemical state characterization, using our newly-acquired ThermoFisher Scientific NEXSA instrument.

My name is Charles Zona, and today we are happy to welcome Doug Meier.

Doug is going to talk to us about X-ray photoelectron spectroscopy, otherwise known as XPS.

He specializes in surface sensitive spectroscopies, such as Auger electron, X-ray photoelectron, infrared reflection absorption, thermal desorption, and low-energy electron diffraction.

Doug was awarded the U.S.

Department of Commerces Silver Medal for his work in the development of conductometric chemical microsensor array technology for the detection of chemical warfare agents.

He also has over ten years of micro beam analysis experience prior to joining McCrone Associates.

Im going to talk with you today about how XPS can be a valuable addition to your analytical toolkit by helping you to characterize the surface properties of your samples.

After that, were going to describe how XPS is used to acquire the surface sensitive data you require.

Following that, well show some examples using some everyday materials to show what XPS can extract in terms of information from that material, after which, well describe the value of ion beam depth profiling for this type of experiment.

For different depths into an object, however, surface can mean different things depending upon what is being interacted with.

For example, there is very little outside of the object that makes it in and performs any chemistry at greater than 1,000 nanometers.

At depths beyond a thousand nanometers, we generally refer to this region as the bulk of said object.

The atoms at the exterior, this top surface layer shown in green, however, is the first thing that an impinging atom or molecule interacts with when it comes into the object.

These surface atoms are the atoms whose properties we need to analyze in order to understand many of the characteristics of materials that we might find in our laboratories.

Depending upon what problems were interested in solving, a surface property can be governed by material that appears at different depths, for example, corrosion properties, and wear, and the appearance of an object.

Is it shiny Is it dull What color is it This information comes from the first hundred or so atomic layers, or more, within a sample.

However, oxidation properties, passivation, and tribology are affected to a greater degree by these atoms that are closer to the surface, but are not necessarily the very exterior of the object, say, 10 atomic layers or so.
