If you missed the Covalent Academy’s 10th Webinar - Surface Spectroscopic Techniques for Chemical Analysis - we have great news! Now available is the quick-to-read eBook, featuring highlights of Dr. Roland Barbosa’s popular webinar, providing a succinct overview, comparison, and analysis of X-ray Photoelectron Spectroscopy (XPS), Ultraviolet Photoelectron Spectroscopy (UPS) and Ion Scattering Spectroscopy (ISS).
XPS is quantitative, acutely surface specific, and can assess oxidation states, chemical bonding environments, electronic properties, and more. UPS and ISS are newer techniques which provide complementary measurements of surface potential and valence band properties, as well as chemical composition of the outermost atomic monolayer (respectively). The new eBook highlights the webinar’s detailed overview of all 3, which can now be executed in correlative analysis to more holistically evaluate the surface properties of your material.
Our world-class expert, Roland Barbosa, brings over 15 years of extensive experience addressing molecular and dynamic aspects of surfaces that impacts real-world problems particularly in the areas of catalysis, corrosion, remediation, semiconductor and energy. He has a PhD in Chemistry from the University of Houston and a BS in Chemistry from the University of the Philippines.
Covalent’s state of the art instrumentation includes the Thermo Scientific Nexsa, providing our clients access to unique industry capabilities. Beyond its cutting-edge integration of the 3 techniques, the Nexsa also resolves several limitations of past XPS instrumentation. Most significantly, its newly designed source, detector, and automation systems enable total-area maps in minutes with a lateral resolution down to 10 µm, without sacrificing meaningful chemical sensitivity.
