Abstract: An atomizing system tar generating an aerosol for inhalation research is disclosed. The atomizing system, in one embodiment, is capable of functioning efficiently at ultra-low liquid and low gas feed rates through the use of a 32 gauge feed line. This feed line reduces dead space in the atomizing system as well as the amount of highly toxic and/or expensive fluid needed to perform the research. An aerosol is generated in a consistent and repeatable manner by injecting fluid at a teed rate of 0.2-20 ?l/min into a gas stream from a compressed gas source at a pressure of 30-60 psi. An adapter is used to connect a syringe containing the fluid to be tested to the 32 gauge feed line.

Abstract: A containment and test system for extremely toxic substances includes a fume hood, a containment compartment such as glove bag or box, positioned within the fume hood, a source of a non-reactive gas to provide a stable environment within the containment compartment, an inline moisture trap coupled to the source of non-reactive gas to dry the non-reactive gas, an ion neutralizer coupled to the source of non-reactive gas to reduce static charges within the containment compartment, a staging area for preparing test samples, a balance positioned within the containment compartment, a stanchion positioned within the fume hood for holding a test animal, and decontaminating apparatus for safely disposing of any toxic substance residue.
