Volatile Organic Compounds, or VOCs, are common chemical compounds that have a high vapor pressure at room temperature, meaning they evaporate at high rates inside. Paints, varnishes, and waxes all have volatile organic compounds, which, as its name implies, can be harmful. Volatile Organic Compounds (VOCs) are chemicals that evaporate easily at room temperature.

When sunlight and heat react with VOCs, sulfur dioxide, and nitrogen oxides (gasses released from many industrial processes and vehicles) ozone is generated, and smog is formed. Volatile organic compounds (VOCs) With the potential to disperse over great distances, VOCs have become a major contributor to global air pollution. Our Dr. Ehrenstorfer range of VOC reference materials has been specifically designed to support you in enforcing global regulation of VOCs in the environment.
