VOLATILE ORGANIC COMPOUNDS (VOC) DETECTION ANALYSIS & MONITORING Volatile Organic Compounds (VOCs) are a diverse group of organic chemicals that easily evaporate at room temperature, often emitting strong odors. These compounds can come from natural sources (such as plants and animals) or from human-made activities, including industrial processes, vehicle emissions, and the use of products like paints, solvents, and cleaning agents. Due to their potential harmful effects on health and the environment, monitoring and detecting VOCs are essential for maintaining air quality and ensuring regulatory compliance. VOCs are a significant concern for air quality, human health, and the environment. Advanced methods for VOC detection, such as GC, PID, and MOS sensors, offer valuable tools for monitoring and mitigating the risks associated with VOC exposure. Continued development in VOC monitoring technology will enable more widespread, real-time, and cost-effective solutions for VOC detection and analysis in various settings.
