Physico-Chemical Testing

EPP offers an extensive range of GLP physico-chemical testing in accordance with multiple guidelines including OECD, OJEC, and CIPAC across a variety of standards such as EEC Council Directives and the EPA.

Our team of highly experienced experts can help you to determine the most suitable set of tests to conduct and align the work with other concurrent activities – for example 5 Batch Analysis – to reduce total project time.

The physico-chemical testing services we provide can address requirements for substance such as agrochemical technical grade active ingredients (TGAIs) and new regulations such as REACH.

Industry wide physico-chemical testing

EPP has significant experience in performing the physico-chemical tests within the agrochemical, pharmaceutical, animal health and industrial chemical fields. 

We can perform (or subcontract*) the tests listed below to help you get your product to market:
