  Angular Resolved X-ray Photoelectron Spectroscopy (ARXPS) Analysis of Polymers
 ARXPS is a powerful technique for examining surface modification of polymers. With Theta Probe the sample is not tilted so the charge compensation conditions remain constant, so changes in peak shape with angle are due to the chemistry of the surface.
 Angular Resolved X-ray Photoelectron Spectroscopy (ARXPS) Analysis of Polymers
ARXPS is a powerful technique for examining surface modification of polymers
With Theta Probe the sample does not have to be tilted so the charge compensation conditions remain constant.
The analyst can be certain that changes in peak shape with angle are due to the chemistry of the surface.

XPS
A simple XPS spectrum of a polymer does not necessarily identify the true chemistry of the surface

ARXPS
Using the angle resolved spectra available from Theta Probe, the grazing emergence electrons reveal the presence of silicone as an ultra-thin surface coating

Polymer Spectra
Quantification of the polymer spectra showing concentration changes as a function of angle
