	Soot agglomerates of combustion generated particles
	Particle generation system with the catalytic stripper technology

A particle calibration facility has been launched by Southwest Research Institute (SwRI) that uses dry soot particles produced by a propane flame based on the miniCAST technology coupled with an SwRI-patented catalytic stripper.

Specifications

This calibration facility is located at Southwest Research Institute in San Antonio, Texas, and is capable of producing:

• Particle mass concentrations ranging from 5 μg/m³ to 80 mg/m³, with less than 5% coefficient of variation

• Particle number concentrations ranging from 10 part./cm³ to 5 x 107 part./cm³, with less than 5% coefficient of variation

• Particle size distributions with geometric number mean diameters ranging from 15 nm to 120 nm

• Flow rates up to 50 standard liters per minute

Instrumentation

This facility is supported with state-of-the-art instrumentation such as:

• TSI's Scanning Mobility Particle Sizer^™

• TSI's Engine Exhaust Particle Sizer^™

• TSI electrometer

• TSI condensation particle counters

• AvL Technologies™ micro-soot sensor

• Sunset Laboratory semi-continuous organic carbon/elemental carbon, with traceable elemental carbon capability

Capabilities

This facility is suitable for:

• Calibration and verification of solid particle measurement systems in compliance with Euro 5, 6 and Euro VI regulations

• Particle instrument and dilution systems calibrations and performance checks

• Research and development on small-scale particle filters (filters can be evaluated at temperatures ranging from 25°C to 400°C)

• Particle inhalation studies

• Fundamental research on the affect of black carbon on global warming
