Ion Mobility Spectrometry for Rapid HEMP Potency Testing - spectrometric testing of technical hemp

The amount of CBD in technical hemp is one of the key harvesting factors for farmers. The solutions that currently exist for them are both time-consuming and costly. This project focuses on determining the day of harvesting the hemp based on data from the ion mobility spectrometer. Samples of cannabis used in this project were collected every two days for one month. Data were represented using spectra captured every 180 ms. These data were preprocessed, cleaned, normalized and the most appropriate predictors were selected, aggregated into one row for each measurement and trained regression models that were able to correctly predict the day of harvest with a mean error of about 1.3 day. Research has shown potential in this area and although the work is not yet final, it offers opportunities for adjustment and improvement.
