Firstly, we used the Raman scattering method which can calibrate in real time to measure the O2 (a1 Δ) yield of SOG for the first time in China. The measurement relative error is less than 8%. Based on the data from the experiments, we report the results that the diluent category and ratios influence the O2 (a1 Δ) yield. The relationship of P-τ values and the O2 (a1 Δ) yield of this SOG were given. The effects of distance and bypass of gas transportation on the O2 (a1 Δ) yield are investigated. Secondly, the chlorine utilization was measured by using Raman spectroscopy simultaneously when the O2 (a1 Δ) yield was measured. This method originated with us. The result about the chlorine utilization is coincident with other theoretic and experimental conclusions. The relationship given in this paper between gas stay time in SOG and chlorine utilization offers reference to improve the reaction efficiency and chemical efficiency of COIL. Finally, the partial water vapor pressure at the exit of SOG was measured by absorption spectroscopy. The water vapor fraction and partial pressure have trends changed with the generator total pressure, the diluentratios, and the BHP temperature. These experimental results are very important to improve experimental conditions of SOG, reduce the water vapor fraction, and enhance the output power of COIL.
