TI  - Chemical and physical properties of ultrafine diesel exhaust particles sampled 
      downstream of a catalytic trap.

AB  - The chemical and physical properties of exhaust particles produced by a 
      Caterpillar 3176 C-12 heavy duty diesel engine equipped with a catalytic trap 
      (CRT) are reported. The engine was operated at 600 Nm and 1500 rpm, using fuels 
      containing 15 and 49 ppm sulfur. A two-stage dilution tunnel designed to simulate 
      the reactions that occur when hot combustion products mix with cooler atmospheric 
      air was used. Particle size distributions were measured using a scanning mobility 
      particle sizer (SMPS) and nano-scanning mobility particle sizer (nano SMPS); a 
      nanomicro-orifice uniform deposit impactor (nano MOUDI) collected size-resolved 
      samples for gravimetric and chemical analysis. A nanometer tandem differential 
      mobility analyzer (nano TDMA) was used to measure the volatility and 
      hygroscopicity of 4-15 nm particles. These measurements confirm that the 
      particles consisted primarily of sulfates.
