Abstract (en)
[origin: WO9306910A1] A sampling apparatus (10) for separating and collecting contaminants contained in an air sample has a first particle separator (18), a second particle separator (20), a coarse filter (22), a denuder (24), a fine filter (26), a semi-volatile organic compound collector (28), a flow rate control device (16), and a vacuum pump (14). The apparatus (10) separates the coarse, intermediate, and fine particles, acid gases, basic gases, volatile organic compounds, and semi-volatile organic compounds at a high flow rate.
