To measure is to know

To measure is to know, is a key principle of risk management. OCAS has a longstanding tradition in measuring potentially hazardous compounds.

REACH* and CLP* regulations improve the protection of human health and the environment from the risks that can be posed by hazardous chemicals. To comply to these regulations, accurate measurements are required not only on the release of these substances from end-products, but also in liquids used during the production process or in air at the workplace.

For more than a decade OCAS has gained experience in checking paints, varnishes and coated samples or air for the presence of potentially hazardous substances. OCAS is equipped to collect the air samples at the customer and carry out the analysis with its state-of-the art equipment.

Case formaldehyde

OCAS investigated the release of formaldehyde, volatile organic compounds (VOC’s) and isocyanates from a range of paint systems as well as from panels coated with these paints to perform risk assessment. The OCAS team chose the best sampling method and analysed these samples with its in-house state-of-the art equipment.

Formaldehyde was measured in water solution using UV-spectrometry after hot leaching tests of coated panels. During painting, the concentration of formaldehyde sampled at the workplace was measured by high performance liquid chromatography (HPLC). Test results were used to compare and rank different coatings and enabled the customer to identify compliant paint formulations.

*REACH: European regulation on Registration, Evaluation, Authorisation and Restriction of Chemicals

*CLP: Classification, labelling and packaging of substances and mixtures.



“At OCAS, measurements are much more than merely a list of results. Thanks to our experience we know how to address these topics. We can help in selecting the best formulations and provide recommendations for adapted collective and personal protection”
