We developed a new desiccator system by improving the conventional desiccator method and measured the FA-removal effects of adsorbents using this system. The improved desiccator system consists of: 1) a pump, 2) a flow meter, 3) a FA gas generator, 4) five connected desiccators, and 5) an exhaust. A more stable concentration of FA in the desiccators was obtained when they were connected in series rather than in parallel. The FA removal rate for 3 days for red tea in used tea bags, green tea, oolong tea, or powdered coffee was more than 80%, and the removal rates for 1 day by activated carbon from palm nutshells and silica gel, as commercially available chemical agents, were 100% and 75%, respectively. This improved desiccator system allows direct collection of air in the desiccator, and may have wide applications.
