Imaging of hydrated systems at resolutions greater than optical is traditionally hard and time consuming. The acquisition of a Zeiss EVO Ls15 environmental SEM at CPG provides us with the ability not only to watch the hydration process at magnifications in excess of 1000x, but also to image without any gold or carbon coating, thus making this technique completely non-destructive.

Cambridge Polymer Group offers electron spin resonance spectroscopy (ESR), also known as electron paramagnetic resonance spectroscopy (EPR), to identify and quantify free radical content in materials. This technique is useful for evaluating antioxidants, shelf-life stability, and the effect of chemicals on materials. Read more...More Product Announcements from Cambridge Polymer Group, Inc.
Cambridge Polymer Group now offers quantitative radiopacity analysis compliant with ASTM F640 "Standard Test Methods for Determining the Radiopacity for Medical Use." In this method, the medical device is imaged with a conventional X-ray system, and the image density contrast is quantified with a densitometer.

Through our work with ASTM, we are developing standards for cleanliness
assessment of medical implants, cleanliness validation, and design of
components for easy cleaning. We also provide testing for plastics that
will be in contact with food. Read more...
Vitamin E Characterization
Vitamin E has become a preferred antioxidant for stabilizing thermoplastics such as ultra high molecular weight polyethylene (UHMWPE). CPG scientists have developed several testing assays to quantify Vitamin E in thermoplastics, and characterize the transformation products of Vitamin E after thermal and radiation exposure.
