Compact VOC emission test chamber

Abstract

The publication presents the test method and construction of a compact VOC emission test chamber. Volatile organic compounds (VOCs) are mainly occur in paint and construction materials containing chemical resins, bitumen, binders, adhesives, etc., as well as residues of unreacted monomers. VOC emission testing is carried out on product samples in environmental chambers in accordance with PN-EN ISO 16000-9. The developed chamber, together with a proprietary control and test parameter acquisition system, allows testing at a stabilized temperature and humidity of air washing over the sample at a specified rate. Qualitative identification and quantitative testing of compounds present in the air inside chambers is carried out using a chromatograph, and the test results are compared with regulations on permissible chemical pollutants in the air of buildings and in atmospheric air. The developed chamber with horizontal sample loading is another version of VOC chambers, developed in response to market demands, offered and implemented in research laboratories by the Łukasiewicz Institute for Sustainable Technologies in Radom.
