Testing Services

All Tests

We are a well-established lab with a highly experienced staff. Whether you require a one off test, ongoing analytical support or a customised programme of work, we are committed to understanding your requirements and delivering the service you need.

The INEOS Laboratory can test a wide range of materials to national and international standard methods (such as IP and ASTM). We also offer a number of in-house methods, tailored to specific streams.

We have an extensive analytical capability, with techniques such as GC; GCMS; ICP; HPLC; IC; XRF; FTIR; UV as well as a range of specialist analytical testing equipment for many applications, such as sulphur and mercury measurement.

Our representative services include:


We can check fuels for contamination by water, solids or other fuels.
