Abstract
Embodiments of the present disclosure provide for collection devices, methods of making collection devices, methods of collecting gases and aerosol particles, and the like.
Claims16
A collection device, comprising:
- an impactor, wherein the impactor removes large aerosol particles;
- a filter pack, wherein the filter pack collects aerosol particles that pass through the impactor, wherein the impactor is disposed on top of the filter pack so that the air flow of the gas into the device passes through the impactor before contacting the filter pack;
- and
- a porous denuder, wherein the porous denuder is a denuder with its wall constructed of a porous material which includes at least one chemical composition that collects at least one type of gas,
- wherein the porous denuder is disposed on the filter pack on the side opposite the impactor so that the gas passes through the filter pack before contacting the porous denuder.
2 more elements
