Laser Induced Plasma Spectroscopy (LIPS) is a technique aiming at measuring local equivalence ratio inside gas turbine combustors without disturbing the combustion fields. In this study, LIPS is applied to well controlled mixtures of gases at the pressure of 1.5 MPa to obtain plasma spectra as calibration. Two types of estimation methods are examined. One is the peak area ratio method in which ratios between particular atomic emissions in the plasma spectra are used. The other is the correlation method where correlation coefficients between the objective and the database spectra are used. The correlation method showed the best performance in terms of precision in the calibration test. Finally, the technique is applied to the measurement of 2.5 MPa combustion gas. The peak area ratio of H656/ N746 provided a good agreement with the gas sampling data, while the peak area ratio of H656/O777 and the correlation data shifted toward higher equivalence ratios. Oxygen quenching is considered as a dominant cause of the shift. In summary, the results showed promising features of the LIPS technique under high pressure conditions. For improving the accuracy further, it is required to take into account the effect of oxygen quenching.
