ABSTRACT:
An emission testing system particularly suited for vehicle emission testing. The system includes at least one research grade non-dispersive infrared (NDIR) unit, a chemiluminescence detector (CLD) unit and a flame ionization detection (FID) unit. All of the analytical units are incorporated in the system for operation with a sample which has been subjected to a single conditioning step. In this manner each analytical unit tests a uniformly conditioned sample. The system is capable of sampling both raw emissions for raw emission idle tests (BAR 90) and dilute volume samples for dilute volume sample mass emission tests under IM-240 regulations.
