Using the petri dish as the sample holder, the absorption of different flours was measured for the wavelength band of 850-1690 because this region of the NIR is quite absorptive when it comes to organic materials. The AvaSphere-50-LS was positioned with the measurement port on the top, with the WS-2 white reflection time used as a reference. As expected, we saw very similar, yet distinctly different absorption curves for all four of the flours. The spectral data processing of this data using derivatives, for example, would accentuate the spectral differences allowing for identification of samples.
