Abstract
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.
Claims25
A denuding apparatus comprising:
- an exposure zone configured to receive a denuding gas;
- a solid denuding surface positioned at least partially within the exposure zone and configured to concentrate a gas-phase species from the denuding gas on the denuding surface;
- a drive system connected to the solid denuding surface, the drive system being configured to move the solid denuding surface relative to the exposure zone while the solid denuding surface is concentrating the gas-phase species from the denuding gas on the denuding surface;
- and
- a sensor configured to sense quantities of the gas-phase species concentrated on the denuding surface while the drive system moves the solid denuding surface relative to the exposure zone and while the solid denuding surface is concentrating the gas-phase species from the denuding gas on the denuding surface.
A denuding apparatus comprising:
- an exposure zone configured to receive a denuding gas;
- a solid denuding surface positioned at least partially within the exposure zone and configured to concentrate a gas-phase species from the denuding gas on the denuding surface;
- a drive system connected to the solid denuding surface, the drive system being configured to move the solid denuding surface relative to the exposure zone while the solid denuding surface is concentrating the gas-phase species from the denuding gas on the denuding surface;
- and
- a sensor configured to sense quantities of the gas-phase species concentrated on a first portion of the denuding surface located outside the exposure zone while the drive system moves the solid denuding surface relative to the exposure zone and while the solid denuding surface is concentrating the gas-phase species from the denuding gas on a second portion of the denuding surface that is positioned within the exposure zone.

(canceled)
A denuding apparatus comprising:
- an exposure zone configured to receive a denuding gas;
- a solid denuding surface positioned at least partially within the exposure zone and configured to concentrate a gas-phase species from the denuding gas on the denuding surface, the solid denuding surface being a surface of a reactive coating on a flexible sheet;
- a drive system connected to the solid denuding surface, the drive system being configured to move the solid denuding surface relative to the exposure zone while the solid denuding surface is concentrating the gas-phase species from the denuding gas on the denuding surface;
- and
- a sensor configured to sense quantities of the gas-phase species concentrated on a first portion of the denuding surface located outside the exposure zone while the drive system moves the solid denuding surface relative to the exposure zone and while the solid denuding surface is concentrating the gas-phase species from the denuding gas on a second portion of the denuding surface that is positioned within the exposure zone.
