Here, we report the design and development of a simple, compact and cost-effective robust optical technique exploiting incoherent broadband cavity-enhanced absorption spectroscopy (IBBCEAS) technique for high-sensitive selective detection and quantitative estimation of gas-phase diacetyl levels in real-time using a visible light emitting diode (LED) operating at 450 nm.

A typical detection limit of ~190 parts-per-billion (ppb) for diacetyl was achieved with an optimum acquisition time of ~4 s at an optimal cavity pressure of 100 Torr.
