Ceram Receives Accreditation for Diisocyanate Analysis

Ceram (UKAS accredited testing laboratory No. 0013), is a leading provider of environmental analysis and has now obtained full accreditation for the analysis of diisocyanates collected in solutions, on glass fibre filters and those in rinse solutions with 1-(2-pyridyl)piperazine derivatization. This includes the sampling trains collected from stack gas emissions following Method 207 and CTM 036.

Although considered toxic, diisocyanates are present in a wide variety of products across a varied range of industries (for example, monomeric diisocyanates are used extensively in the automotive and building insulation industries for the manufacture of polyurethane foams, fibres, coatings (paints and varnishes) and elastomers). Exposure to this group of compounds is reported to result in hypersensitivity pneumonitis and occupational asthma and, to reduce the risk of developing these conditions, worldwide Occupational Exposure Limits (OELs) have been established.

As a result of their use in a variety of products, diisocyanates are one of many compounds that can be emitted from industrial processes via chimney stacks, ventilators or other static sources. Integrated Pollution Prevention and Control (IPPC) requires the operators of these processes to regularly report their atmosphere emissions to a relevant regulatory authority such as the Environment Agency (EA). Analysis of samples taken by MCERTS accredited protocols should where possible be conducted by UKAS accredited testing methods.
