Volatile organic compound - Wikipedia

Volatile organic compounds (VOC) are organic chemicals that have a high vapour pressure at room vapor pressure correlates with a low boiling point, which relates to the number of the sample's molecules in the surrounding air, a trait known as volatility.. VOC's are responsible for the odor of scents and perfumes as well as pollutants.

Introduction to VOCS and Health | Indoor Air Quality (IAQ) …

The term TVOC refers to the total concentration of multiple airborne VOCs present simultaneously in the air. TVOC methods do not measure all VOCs in the air, but a subset of VOCs that are expected to be present. Measuring TVOC concentrations is less expensive than measuring the concentrations of many individual VOCs. However, there are two main limitations to TVOC measurements. First, different …
