Chemicals
As with the pharmaceutical industry, Butterworth Laboratories is capable of providing the chemicals sector with an exceptional analytical support service, as we have an established history of working with companies in the petrochemical, polymer and plastics industries. Furthermore, the majority of our analytical staff have worked as analytical chemists across various industries prior to joining our staff team, creating a pool of expertise to solve the most complex of testing requirements.
As members of the UK Good Laboratory Practice (GLP) Compliance
Programme for Phys/Chem Testing, we are able to undertake the regulatory
testing for health and environmental safety studies, and some other
testing that will be submitted to regulatory authorities for the
purposes of Risk Assessment.
Over the years the analytical chemists at Butterworth have handled a very diverse range of materials from plastics for cars and electrical equipment, through polymers for fast food containers to soaps and detergents. Where possible these have been analysed to the relevant published methods, such as BS, EN, ISO, DIN, ASTM, IP and AOAC.
Butterworth also undertakes work to aid companies with problem solving, and the validation of, manufacturing processes in addition to routine QC testing of raw materials and finished products.
Recent investigations include:
- Cause of adverse coloration of a batch of industrial filters
- Potential release of toxic chemicals on heating filter materials above operational temperatures
- Cause of different odours between two batches of the same solvent
- Potential extraction of plastic additives by a cosmetic raw material during long term storage
- Level of butane and propane blowing agents in polyurethane foam
