Development of Multi-hydrocarbon Component Measurement Method Using TDLAS

Abstract

In this study, we developed a technology that can detect multi-hydrocarbon component in a wide range of 100nm with 3μm high-speed scanning laser system based on difference frequency generation method lasers and tunable diode laser absorption spectroscopy (TDLAS). The applicability of simultaneous multi-hydrocarbon components measurement technology in the engine process was evaluated. TDLAS with 3μm high-speed scanning laser system is capable of mixture measuring and has the potential for practical application.
