                         using combined measurements of wavelength shift (\Δ 
                         \λ0) and reflectivity difference (\Δ R). The method 
                         relies on plotting the measurement data on the\Δ R-\Δ 
                         \λ0 space and exploits in the identification process the 
                         effect of significant loss behavior of bulk silicon near or within 
                         the visible range (for lossless gas vapors). It has been validated 
                         by reflectivity measurements on a Fabry-P{\'e}rot cavity 
                         resonating around 745 nm for four different gas vapors whose 
                         reflective indices are close to each other and by two metrics for 
                         separability/identification analysis by the scattering matrix 
                         method. It is noted that the combined measurements of\Δ 
                         \λ0 and\Δ R result in better identification than that 
                         obtained by the measurement of\Δ \λ0 (or\Δ R)
