Device manufacturers define the acceptance criteria for their implants. From early-stage protein confirmation to GLP-compliant EDSP and allergenicity testing, we help you make faster, more informed development decisions and comply with evolving global regulations of genetically engineered crops.

Corrosion Testing | ASTM F | EAG Laboratories

The potentiostat is connected to these three electrodes, and the potential of the working asm, with respect to the reference, is scanned through a voltage range from negative to positive, and then reversed to its starting potential. This website uses cookies to improve user experience.

Our scientists offer expertise in technology, life sciences, electronics, industrial and consumer products, having tested a broad array of materials for legal challenges. This lead allowed both electrical connection to the potentiostat as well as suspension in the test solution. The upper limit on device size is dictated by the electrical current qstm capability of the test apparatus see Section 6.

Having helped develop the test methods that shape current regulatory guidelines, EAG chemists, biologists and toxicologists have evaluated the environmental impact of thousands of active ingredients and formulations—from pesticides and pharmaceuticals to industrial chemicals and consumer products.

Using state-of-the-art equipment and innovative techniques, we conduct expert imaging to aid in failure analysis, dimensional analysis, process characterization, particle identification and more.
