Low-Flow Thermodenuder - 3065
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.
Features & Benefits
- Removes gaseous precursors and volatile particles
- Continuous, flow-through design
- Compatible with SMPS systems
Applications
- Determining fractions of solid and volatile components in vehicle exhaust*
- Measuring emissions from direct-heating boilers, exhaust from industrial stacks, and emissions from biomass burning
- **Applications relate to use of the Thermodenuder with an SMPS system.
