Abstract
Passive sampling method for measuring total volatile organic compounds (TVOC) in indoor air was explained in this article. TVOC means the amount of volatile organic compounds (VOC) in indoor air. TVOC measurements have been beneficial in determination of indoor air pollution by VOC. In many studies, TVOC measurements have been done as Sum of VOCs which is the total value of individual VOC. But, TVOC measurements occasionally have been done as total area with response factor of toluene. Passive sampling for TVOC is suitable for indoor air quality survey, because it is convenient. Since TVOC is composed of different VOC of various physical-chemical properties, adsorbents that have high adsorption / desorption efficiency are recommended to use for the passive sampler. And samplers that have high SR are recommended to select. TVOC measurements by passive sampler are expected to have high performance as screening method. Furthermore, it will be necessary to consider recalculation of TVOC concentration carried out by applying unique sampling rate values of some VOC and estimated value of sampling rate to the retention time of total ion chromatogram for accurate quantification.
