Abstract: A passive sampling apparatus and method for measuring the cumulative mass of a selected gas being transported through a known cross-sectional area, for example, a soil surface, during a chosen period of time, using absorbent material, are described. Two quantities of absorbent material are disposed in a hollow container, such as a pipe section, and spaced apart such that they may be readily separated for analysis. The absorbent material closest to the soil captures the gas leaving the soil. Under reversed flow conditions, for example when the ambient air enters the ground because of fluctuations in atmospheric pressure, the upper absorbent material captures the component of interest entering the apparatus, thereby preventing this gas from entering the lower material and disturbing the measurement. The apparatus can therefore sequester the component of interest without being affected by the direction of gas transport.
