Polymers & Plastics
Polymers and plastics are used in many fields such as food grade packaging and medical technology. Their composition is especially important when the polymers get in direct contact with food or humans. With EnviroESCA the concentration of hazardous contaminations can be quantified regardless of their vacuum compatibility.
Investigation of a superabsorbent polymer (SAP) with EnviroESCA
Drying and shrinking of the SAP sample in the analysis chamber can be observed easily with the sample observation camera. The sample position was adjusted for each measurement to keep the sample surface in focus, which is also visible in this time-lapse animation.

Investigation of polymers and plastics with EnviroESCA
This application note describes how EnviroESCA can be used to analyze the surface of polymers and bulk insulating material. EnviroESCAs ability to perform X-Ray Photoelectron Spectroscopy (XPS) at non vacuum conditions shows its main advantage when being applied to insulating material. Specimens that tend to charge up under vacuum conditions and need to be extensive charge compensated with expensive low energy electron and low energy ion sources can be measured with ease and without the problem of overcompensation.
