Abstract:
1. A bioaerosol collection system comprising: a humidifier to increase the humidity of a continuously flowing sample volume using a biocompatible liquid vapor for humidification, wherein the continuously flowing sample volume comprises one or more bioaerosols in a gas stream; and an amplifier to condense vapor of the biocompatible liquid on the one or more bioaerosols of the continuously flowing sample volume from the humidifier, thereby amplifying particle sizes of the one or more bioaerosols, wherein humidification is performed in a heating tube within the humidifier and amplification is subsequently performed in a cooling tube within the amplifier; and the heating tube and cooling tube are positioned to be parallel to each other such that the continuously flowing sample volume enters the amplifier after exiting the humidifier.
