Example of FTIRμS spectra. Example of FTIRμS absorption (A) spectra. The vertical lines define the parts of the spectra that were used for the quantitative analysis,

i.e. 700 cm-1 ≤ ν ¯ ≤ 1710 cm-1. With (a) pure component spectra of the internal standard NaN3 (black), collagen (1.35 g/ml, dark gray) and chondroitin sulphate (3.19 g/ml, light gray); and (b) sample spectra from a single FOV at d = 100 μm for 0 weeks (gray) and 72 weeks (black).
