What are extractables and leachables, and why are they analyzed?

Extractables are chemical substances that may be extracted from a material by solvents under accelerated or extreme conditions. Leachables are substances that actually migrate into the final product under real conditions of use. These analyses are particularly important in the pharmaceutical, medical and food sectors to ensure that materials in contact with products do not introduce unwanted contaminants. TERA Environnement performs extractables and leachables analyses in accordance with applicable standards and guidelines.
