White Paper: Gravimetric Analysis in Emissions Testing

Diesel engines generally emit less CO2 than combustion engines, but more nitrogen oxide and particulates. These extremely small particulates pose a danger to human health and have led to significant reductions of regulatory limits on particulates emissions over the past decades.  

These limits mean there is a need for highly sensitive detection methods to reliably detect the smallest particle quantities. Gravimetric measurement has become the standard method of legal exhaust measurement, offering both direct traceability and calibration.
