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

Table 1

Boundaries of each peak used for the peak fitting method. The ν4PO4 area contains 4 peaks, the ν1ν3PO4 area contains 5 peaks, and the amide area contains 8 peaks. Each peak’s parameter (height, FWHM, and position) is searched between the defined minimum and maximum boundaries, expressed in the table, by the fitting algorithm.
