Fiber Optic Coupled Raman Based Detection of Hazardous Liquids Concealed in Commercial Products

Figure 2

Raman spectra of acetone, hydrogen peroxide, and an acetone peroxide mixture contained in a clear glass bottle. Parameters were 785 nm, 10 s acquisition time at 200 mW of laser power. The characteristic peak for acetone is located at 798 cm⁻¹ and for peroxide at 878 cm⁻¹. The main acetone peroxide peaks are located at 588 cm⁻¹, 780 cm⁻¹, 890 cm⁻¹, and 936 cm⁻¹.
