Black Carbon Particle Calibration
Calibration facility uses dry soot particles produced by a propane flame based on the miniCAST technology coupled with a catalytic stripper. Specifications: Particle mass concentrations ranging from 5 g/m to 80 mg/m, with less than 5% coefficient of variation; Particle number concentrations ranging from 10 part./cm to 5 x 107 part./cm, with less than 5% coefficient of variation; Particle size distributions with geometric number mean diameters ranging from 15 nm to 120 nm; and Flow rates up to 50 standard liters per minute. Capabilities include: 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 25C to 400C); Particle inhalation studies; Fundamental research on the affect of black carbon on global warming.
