Automation of the Peak Fitting Method in Bone FTIR Microspectroscopy Spectrum Analysis: Human and Mice Bone Study

Figure 6

Original spectrum in the ν1ν3PO₄ area (dark blue line) recovered by the Gaussian sum fitting (dotted-black line) and the 5 individual peaks beneath (full lines). The two peaks directly used to compute the Mineral Maturity parameter are the 1030 cm⁻¹ peak (purple line) and the 1110 cm⁻¹ peak (dashed-green one).
