Using sensitive micro balances in temperature and humidity controlled chambers, SwRI measures exhaust particulates from gasoline.

Emissions characterization for regulated, non-regulated, and other air toxic components is an essential part of fuel and fuel additive registration. SwRI has more than 50 years of experience as a non-biased testing facility and can assist clients worldwide in fuel and fuel additive registration requirements.

Regulated Emissions

  • Total hydrocarbons
  • Oxides of nitrogen
  • Carbon monoxide
  • Particulates

Non-Regulated Emissions

  • Individual hydrocarbons (up to C12)
  • Aldehydes and ketones
  • Alcohols and ethers
  • Polycyclic aromatic hydrocarbons (PAH)
  • Nitrated polycyclic aromatic hydrocarbons (NPAH)
  • Polychlorinated dibenzodioxins and dibenzofurans (PCDD/PCDF)
  • Products containing atypical elements

Greenhouse Gases (CO2, N2O, CH4)

Air Toxics

Hazardous Air Pollutants (HAP)
