Lightnovo research demonstrates a fast, handheld alternative to chromatography for in-field pCB profiling
We are pleased to announce the publication of our latest scientific article:
“Portable Raman Spectroscopy for Non-Invasive Chemotype Identification and pCB Profiling in Cannabis”
📄 Published in the Journal of Raman Spectroscopy (Wiley).
This study highlights how compact, hand-held Raman spectrometers—including Lightnovo technology—can efficiently differentiate cannabis chemotypes and support rapid, non-destructive analysis directly in the field.
Why This Matters
The cannabis industry depends heavily on identifying chemotypes (THC-dominant, CBD-dominant, intermediate, etc.) and monitoring phytocannabinoid (pCB) content to ensure:
-
regulatory compliance
-
product quality
-
optimized cultivation
-
early-stage plant selection
Traditional methods such as HPLC and GC are accurate but slow, invasive, expensive, and unsuitable for high-throughput in-field measurements.
What the Study Shows
Using two portable Raman spectrometers (785 nm / 46 mW and 830 nm / 76 mW), researchers collected spectra from:
-
cannabis leaves (chemotypes I and III)
-
THC distillate
-
CBD standard
Machine learning was applied using PLS-DA classification, achieving:
90% prediction accuracy
for chemotype differentiation using the 830 nm system.
This confirms handheld Raman as a powerful tool for rapid, non-invasive, in vivo plant screening, even at early vegetative stages.
Additionally, the study highlights:
✔ clear identification of pCB-associated Raman peaks
✔ capability for deeper pCB profiling
✔ PCA showing strong potential for future pCB quantification with calibration models
Applications & Impact
The findings demonstrate significant potential for handheld Raman spectroscopy in:
-
in-field chemotype identification
-
THC/CBD monitoring for regulatory compliance
-
screening cultivars during early growth
-
quality control for cannabis-derived products
-
optimizing greenhouse and open-field cultivation
This opens the door to fast, affordable, and non-destructive cannabis analysis—with no sample preparation, no chemicals, and no laboratory infrastructure required.
