Volatile Organic Compound Analysis (VOCA): A System for Evaluating Atmospheric Contaminants on Plant Growth

A set of contained environment chambers have been designed to study the effects of Volatile Organic Compounds (VOCs) on plant growth and development. The Volatile Organic Compound Analysis (VOCA) system consists of six Lexan chambers, each with independent VOC monitoring and control capacities. The VOC exposure chambers are located within a larger controlled environment chamber (CEC) which provides a common air temperature, photoperiod, and light control. Relative humidity, CO₂ concentration, and VOC concentration of the atmosphere are independently controlled in each VOCA exposure chambers. CO₂, air temperature, relative humidity and PPF are continuously monitored with software developed using IOControl™ and IODisplay™.
