Pre and Post-processed spectra of the complete set of samples (n = 249) obtained using the NIR diffuse reflectance spectrometer in the wavelength region 1350–2500 nm. (A) The pre-processed (in absorbance) raw spectra for all 249 samples, including triplicate technical replicates. (B) The processed spectra for the models that were not derivatised. Includes models: CBN (19,097), CBC (19,096), CBGA (19,164), CBG (19,164), CBDV (17,199), THCV (19,161) and CBD (19,156). (C) Processed spectra that have been derivatised under first order derivatisation for CBDA (19,137), Δ9-THC (19,158), Δ9-THCA (19,179) and THCVA (19,180). For this figure a derivative data transformation was undertaken. The y-axis is the absorbance of reflected molecules in the test samples, the x-axis is the measured wavelength (nm). All spectra values were obtained from the Hone Create Platform. All processed spectra were determined from the software algorithms.
