Analysis and Consulting

Product development and troubleshooting:

Structural analysis characterises plastic materials used in manufacture.

Techniques include FTIR, DSC, TGA among many others.

Gas Transmission Testing

Oxygen  and Water Vapour Transmission testing - OTR and WVTR or MVTR  gives you the data you need to best control the shelf life of your product.

Our suite of Mocon Ox-Tran & Permatran instruments are the most reliable for the job.

Benchmark the performance of a new product to establish a specification.

In a tendering process, compare performance of offerings from different suppliers.
