Advantages of Micro VOC Emission Test Chamber

• The coated stainless steel wall improves the adsorption capacity of VOC test chamber for high-boiling-point materials and polar compounds. The recovery rate of tetradecane and 4-phenyl-1-cyclohexene can achieve more than 80%.
• The micro VOC emission chamber provides standard testing environment and main testing items include VOC concentration, SVOC concentration, water content and so forth.

This micro VOC emission chamber adopts ISO 12219-3:2012 (en) screening method for the determination of the emissions of volatile organic compounds from vehicle interior parts and materials-Micro-scale chamber method.

The patent is about how to deal with the connection surface between VOC emission chamber and the testing object. The technology helps to reduce the surface adhesive force, largely reducing VOC’s adhesiveness on chamber’s interior wall. In this way, the testing result of samples stored in the sampling bag is more close to the result of testing object in chamber, and the testing precision of emission chamber is largely improved.
