Thermodenuder Model 3105

Description

Perform particle volatility studies at well-controlled temperatures up to 300°C with long residence times. The Thermodenuder allows semi-quantitative studies to be performed on the volatile species and mixing state of sampled particles at temperatures up to 300 C.

With only 15 minutes or less required to reach a desired temperature, studies at multiple temperatures can be performed over a short time period. An integrated activated carbon denuder minimizes re-condensation of volatilized species onto particles. When integrated with the Model 3100 HTDMA, the Thermodenuder allows detailed, size-dependent studies of how volatile species influence aerosol water uptake.
