Ventilation is the most effective procedure to reduce indoor air pollutant. Volatile organiccompounds (VOCs), which cause health related symptoms, are often detected in the indoorenvironment. The way of ventilation should be decided depending on the level of VOCs. Thelevel of VOCs and ventilation rate are usually measured individually. This study will proposea simple method to measure both the ventilation rate, by perfluorocarbon tracer gas technique(PFT), and VOCs concentration immediately by using a single sampler. A glass vial with adiffusion cap on top was selected as a tracer source, filled with perfluorocarbon (PFC). Athermal desorption (TD) tube packed with carbon adsorbent was used as a sampler. TD and agas chromatograph-mass spectrometer (GC-MS) was employed for injection and analysis,respectively. Selected analysis conditions enable to separate VOCs and PFC. According tothis method, low cost, less complexity and shorter time for analysis are made possible.
