Operator Manual: Single Particle Soot Photometer (SP2)

The SP2 directly measures the black carbon, known as soot, in individual aerosol particles. Its high sensitivity, fast response, and specificity to elemental carbon make it the premier instrument for the following tasks:
• Characterizing pollution sources
• Characterizing soot in snow, ice or water
• Calibrating Aethalometers
• Documenting thin, atmospheric layers of contamination
