Claim:
1. A denuding apparatus comprising: a duct configured to receive a denuding gas flow; a solid denuding surface positioned at least partially within the duct and configured to concentrate a gas-phase species from the denuding gas flow 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 duct while the solid denuding surface is concentrating the gas-phase species from the denuding gas flow 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 duct and while the solid denuding surface is concentrating the gas-phase species from the denuding gas flow on the denuding surface.
