Abstract
Ventilation is the most effective procedure to reduce indoor air pollutant. Volatile organic compounds (VOCs), which cause health related symptoms, are often detected in the indoor environment. The way of ventilation should be decided depending on the VOCs level. VOCs level and air exchange rate are usually measured individually. This study will propose a simple method to measure both the ventilation rate by perflourocarbon tracer gas technique (PFT) and VOCs concentration at once by using a single sampler. A glass vial with a diffusion cap on top was selected as a doser, filled with perfluorocarbon (PFC). A thermal desorption (TD) tube packed with carbon adsorbent was used as a sampler. TD and a gas chromatograph - mass spectrometer (GC-MS) was employed for injection and analysis, respectively. Selected analysis conditions enable to separate VOCs as well as PFC. According to this method, low cost, less complex and shorter time for analysis were to be possible.
