Dekati® Thermodenuder is used to remove volatile and semivolatile compounds from aerosol sample in order to eliminate unwanted sample transformations e.g. in engine exhaust measurements. The volatile and semivolatile compounds are vaporized when they enter the instrument and then adsorbed into active charcoal which has been designed to the form of mats for ease of use. The Dekati® Thermodenuder is especially suitable for use with the ELPI+™ (Electrical Low Pressure Impactor) and the DMM (Dekati® Mass Monitor), also manufactured by Dekati Ltd, but can be used with any measurement device with a suitable flow rate.
