Time-Resolved Measurements of Exhaust PM for FTP-75:Comparison of LII, ELPI, and TEOM Techniques

Abstract
A direct comparison is made of time-resolved measurements of diesel PM emissions obtained using laser-induced incandescence (LII), an electrical low pressure impactor (ELPI), and a tapered element oscillating microbalance (TEOM). The measurements were made on two diesel passenger vehicles, one of wh
