XPS – UPS – ISS: Surface Spectroscopic Techniques for Chemical Analysis

Live event scheduled for June 11th, 2020 at 11:00 AM PDT

Covalent Metrology recently announced the completed installation of its new Thermo Scientific Nexsa XPS system, which incorporates 3 of the most useful surface chemical techniques available: X-ray photoelectron spectroscopy (XPS), ultraviolet photoelectron spectroscopy (UPS), and ion-scattering spectroscopy (ISS). Join Covalent Academy this week to deepen your knowledge on these 3 techniques: what they do best, how they can work together, and what each can do for you!

If you’ve never heard of one, or all, of those techniques before: worry not. Our surface characterization expert, Dr. Roland Barbosa, will introduce key theoretical and operational concepts for these tools before exploring the practicalities of their applications.

The event, XPS-UPS-ISS: Surface Spectroscopy for Chemical Analysis, will be aired live at 11am PDT on June 11th, 2020.

Signal photo-electrons and scattered-ion fragments escape only the outermost few nanometers of a surface. This allows you to measure true surface chemistry, and detect contaminants and chemical features most relevant to the surface properties of your material: its roughness, adhesion, bonding potential, grain structure, wettability, diffusion characteristics, zeta potential, and many more.

Learn how to use these 3 techniques to probe the chemical properties of your surface, and how correlative analysis between them can clarify greater insights into your sample.

THIS WEBINAR WILL ANSWER:

  • What is XPS? UPS? ISS? How do they work?
  • What should I consider when applying each technique?
  • How can they be used together?
  • What are the kinds of applications they work for?
  • How can I ensure the best data with each technique?
