Sensor for Detection of Formaldehyde Gas
Project ID: D2021-02 Background Formaldehyde (CH2O) is a volatile organic compound (VOC) that has been classified as one of the most toxic carcinogens by both the World Health Organization (WHO) and the United States Environmental Protection Agency (US EPA). Since formaldehyde gas can damage the nervous and immune systems, the WHO has set a maximum...
