VOC and other harmful substances test

Hazardous substance detection refers to the production status of substances in daily life and their contact with human beings, which may cause disease or health decline. Through the management and control of toxic and harmful substances, it can ensure that raw materials and processed products meet the environmental requirements of national non-toxic, low toxic and environmental protection laws and regulations, so that products can enter the domestic and foreign markets, meet the requirements of customers and the development trend of environmental protection.

Contents of hazardous substance detection RoHS / Rap / SVHC / posh / WEEE / detection, antioxidant detection, flame retardant detection, mold resistance detection, UV absorption detection, phthalic acid detection, polycyclic aromatic hydrocarbons detection, perfluorooctane sulfonic acid detection, asbestos detection, perfluorooctane sulfonic acid and salt detection, toy 19 heavy metal detection, VOC detection, azo detection, cod detection, etc. Detection range of hazardous substances Electrical and electronic products, food and contact materials, toys and children's products, clothing / luggage / shoes, automotive materials and parts, metal minerals, petrochemical, polymer materials, consumer goods, packaging materials, building materials / decorative materials, water quality, etc.
