Applications
- Pollution characterization
- Air quality and visibility
- Atmospheric and climate research
- Health effects studies
- Combustion emissions
- Black carbon in water, ice, snow
Measured Parameters:
- Single-particle laser incandescence
- Single-particle light scattering
- Temperature
- Pressure
Derived Parameters:
- BC mass distribution as a function of particle diameter
- Particle number distribution as a function of particle size
- Aerosol medium: Air, 0-40°C
- Response time: 1Hz for standard output products
- Sample flow: 30-180 volumetric cm3/minute (typically 120)
- Particle size range:
# Scattering signal: 200-430nm diameter (this range encompasses the accumulation mode of most particles, i.e., range where most mass is found). This range can be extended to 700nm by doing postprocessing of saturated signals.
# Incandescent signal: Depends on particle density, but 70-500nm mass-equivalent diameter assuming a black carbon density of 1.8g/cm3 - Number concentration range:
# 25,000 particles/second.
# 0-12,500 particles/cm3 at standard flow rate of 120 volumetric cm3/minute Ss
