Dust Characterization

Dust Characterization analyzes both microbial and non-microbial particles found in dust samples, including skin cells, fibers, pollen, insect debris, and other particulates.

This analysis is often performed alongside Air-O-Cell® cassettes or other sampling media to help identify potential fungal allergens. It is an ideal first step for initial site surveys when Indoor Air Quality (IAQ) concerns are present, particularly in situations where mold levels are low but occupant symptoms persist. 

Results may be reported qualitatively or quantitatively, depending on project needs.

 

• Identifies and characterizes particulates within a sample
• Useful for evaluation potential non-microbial IAQ issues
• Supports investigations where irritants are suspected but mold levels are minimal

 

The Microbiology Division accepts the following media for Dust Characterization analysis:

• Spore traps
• Tape lifts
• Swabs
• Bulk materials (e.g., sheetrock, carpet)
• Amorphous bulk materials (e.g., house dust)
• Liquid samples

 

Particle types are identified using light microscopy and Phase Contrast Microscopy (PCM).

 

More advanced analytical options are available through our Materials Science Division, including ash analysis, char identification, and comprehensive particle identification, if required.
