The science
How Does Cannabis Potency Testing Work?
The Purpl PRO uses near-infrared spectroscopy (NIRS), a proven, non-destructive technology trusted in agriculture and pharmaceuticals for decades.
When light interacts with a cannabis sample, the device reads the molecular fingerprint and translates it into potency data.
Our system is calibrated against high-performance liquid chromatography (HPLC) lab data to deliver highly accurate results without the cost or wait of lab testing.
