Description:
Mass balance is a commonly used approach for characterizing the source and sink behavior of building materials. Because the traditional sink test methods evaluate the adsorption and desorption of volatile organic compounds (VOC) at ambient temperatures, the desorption process is often incomplete. To achieve nearly complete desorption, a high temperature dynamic chamber method was developed and evaluated. The method was tested by spiking a known amount of VOC onto an aluminum weighing dish or building material and then placing the sample in the high temperature dynamic chamber for desorption at 60 or 65 °C. The results demonstrated that it is a useful technique for studying indoor sink effects.
