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.

Abstract: A method and its possible embodiments are presented for collecting airborne biological and non-biological agents and concentrating them into small amounts of liquid. Airborne particles are drawn into the sampler and by the action of an electrostatic field are deposited on the collection electrode covered with superhydrophobic substance (surface contact angle >150°). At the end of the sampling period a small liquid droplet (5-60 ?L) is injected at the top of the sampling chamber. Since the sampler is positioned at an angle to the horizontal, the droplet rolls-off of collection electrode's surface under the force of gravity and removes the deposited particles. The droplet is then collected by a liquid capture system. The particles concentrated in such small amounts of liquid facilitate sample analysis by various techniques. The suggested sampler's embodiments achieve sample concentration rates higher than 1×106/min which will allow detection of very low particle concentrations.
