Volatile organic matter definition

The analyses of the air-dried equilibrated sample for moisture, ash, and volatile matter are collectively termed the proximate analysis. Fixed carbon is, by definition, the difference between 100 and the sum of the analytes (moisture, ash, volatile matter). The proximate analysis gives information on the classification of coal by measuring the relative percentage of volatile and nonvolatile organic matter as those of moisture and noncombustible mineral matter. 

Reductions of volatile organic compounds (VOCs) which are ozone-forming constituents, must only be met in the summertime. However, the emission requirements for air toxics applies year-round. The definition of air toxics includes benzene, 1,3 butadiene, polycyclic organic matter (POM), formaldehyde and acetaldehyde.
