Single Particle Soot Photometer – Extended Range (SP2-XR)

 
The Single Particle Soot Photometer – Extended Range (SP2-XR) delivers accurate, real time, size resolved single particle measurements of black carbon mass and size with direct output suitable for monitoring applications

 

Applications

  • Characterizing air pollution sources
  • Detailed single particle data enables accurate description of optical properties and prediction of health effects
  • Validating other black carbon-measuring instruments like the Aethalometer

 

Advantages

The SP2-XR offers many advantages:

  • Real-time output of black carbon mass and particle size for individual particles
  • Straightforward data analysis due to intuitive, streamlined direct output of measured and derived parameters, including mass and particle size
  • Incandescent particle detection as low as 50 nm targets particles critical to primary pollution characterization
  • Smaller, lighter package is easily deployable in field applications, and occupies less space on an aircraft
  • Simplified maintenance – i.e., calibration, alignment, cleaning
  • The SP2-XR user interface enables straightforward data analysis due to intuitive, streamlined direct output of measured and derived parameters including mass and particle size

 

Software

The SP2-XR user interface enables straightforward data analysis due to intuitive, streamlined direct output of measured and derived parameters including mass and particle size

 

SP2-XR Data Analysis Toolkit

The SP2-XR toolkit serves to process calibration data and produce a threshold table which is directly imported in the SP2-XR software. This allows for quick analysis of scattering and incandescence calibration data, and real time output of black carbon mass and particle size.

  • Quickly analyze scattering and incandescence calibration data
  • Produce a threshold table, which is imported into the user interface of the SP2-XR to allow for real-time conversion of the SP2-XR to black carbon mass and particle size

How It Works

High optical power intra-cavity Nd:YAG laser heats light-absorbing particles to the point of incandescence

Single particle incandescence is measured and correlated to black carbon mass

Single particle light scattering is measured and used to indicate particle size, non-BC containing aerosol number, and mass concentrations
