Fiber sampler for recovery of bioaerosols and particles
First Claim
1. A method for collecting aerosols, comprising:
- providing an aerosol humidifying device having therein a) a first temperature and humidity controllable gaseous environment and b) a second temperature and humidity controllable gaseous environment, the first and second temperature and humidity controllable gaseous environments separated only by a permeable partition member having a polymeric wall;
delivering, as the aerosols to be collected, bioparticles from outside into a first gas stream of the first temperature and humidity controllable gaseous environment;
humidifying or dehumidifying the bioparticles in the first gas stream of the first temperature and humidity controllable gaseous environment by transport of water from a second gas stream of the second temperature and humidity controllable gaseous environment across the permeable partition member and into a vapor phase of the first gas stream, the permeable partition member preventing contamination between a) the first gas stream of the first temperature and humidity controllable gaseous environment including the bioparticles and b) the second gas stream of the second temperature and humidity controllable gaseous environment; and
collecting the bioparticles by a collection medium.

Abstract
An aerosol collection system and method. The system includes a bio-aerosol delivery device configured to supply bioparticles in a gas stream, a moisture exchange device including a partition member coupled to the gas stream and configured to humidify or dehumidify the bioparticles in the gas stream, and an aerosol collection medium downstream from the moisture exchange device and configured to collect the bioparticles. The method includes delivering bioparticles in a gas stream, humidifying or dehumidifying the bioparticles in the gas stream by transport of water across a partition member and into a vapor phase of the gas stream, and collecting the bioparticles by a collection medium.
