AOTF-NIR Qualitative Analysis of Loaded Additives and Resins

A Brimrose Free Space spectrometer was used to collect spectra of five compounds that contain polymer additives, three of which were samples that contained highly loaded additives and two that were resins that contain these additives. A PCA model was clearly able to distinghish between the five compounds. The spectra showed clear peaks that contain relevant spectral information for quantitative analysis of the level of additives in these compounds.
