Continuous diffusion denuding with moving denuding surface

摘要

A duct can be configured to receive a denuding gas flow. A solid denuding surface that is connected to a drive system can be configured to move the solid denuding surface within the duct while the solid denuding surface is continuously concentrating one or more gas-phase species from the denuding gas flow on the denuding surface. Also, a denuding gas flow can be passed along a denuding surface to concentrate one or more gas phase species from the denuding gas flow onto the denuding surface with a diffusion denuding action. The denuding surface can be moved while continuing to concentrate the one or more gas phase species from the denuding gas flow onto the denuding surface.

主权项

1. A method comprising:
passing a denuding gas flow along a solid denuding surface in an apparatus to concentrate one or more gas phase species from the denuding gas flow onto the denuding surface with a diffusion denuding action; moving the denuding surface relative to one or more other portions of the apparatus that border the denuding gas flow, while continuing to concentrate the one or more gas phase species from the denuding gas flow onto the denuding surface; and while moving the denuding surface and continuing to concentrate the one or more gas phase species from the denuding gas flow onto the denuding surface, continuously sensing quantities of at least one of the one or more gas phase species concentrated on the denuding surface.
