LOW-FLOW THERMODENUDER,TSI 3065,熱擴散管

The presence of volatile particles and their precursors in particulate exhaust emissions can have great influence over the size measurement when the exhaust cools and dilutes. The Low-Flow Thermodenuder removes precursors and volatile particles from an aerosol sample for subsequent measurement of dry particle size. It is optimized for use with TSI Scanning Mobility Particle Sizer? (SMPS) systems.

The Thermodenuder works by heating the aerosol to a preset temperature (0 to 400°C ± 1 K) and adsorbing any volatile particles. Active carbon is the adsorption material. This accessory operates within a flow range of 0.2 to 2 L/min, with optimal flow at 0.5 to 1 L/min.
