Here we present the near ambient pressure characterization of the surface of a superabsorbent polymer (SAP) as an example of functional material analysis under application relevant conditions. EnviroESCA's ability to work in real world sample environments allows XPS surface analysis of hydrophilic polymer samples loaded with different amounts of water. Neutralization of this insulating product is accomplished by Environmental Charge Compensation enabling X-ray photoelectron spectroscopy on these type of materials with ease.
