Analysis
The spectrum is the mass absorption coeffcient (MAC, cm2/g). It is constructed from the MAC curves of KBr and PE pellets containing different masses of sample. The effect of the KBr and PE matrix is taken into account following the procedure described in Mennella et al. (1998). The error on the measured MAC is the quadratic sum of the uncertainty on the thermal stability of the spectrometer and on the uncertainty on the mass of sample in the pellet. The analysis of the spectral data to reconstruct the MAC of the samples and the details on the error determination are explained in Demyk et al. (2017).
