Selective Separation Spectroscopy
LightLab was designed to be easy to use and yet delivery lab-grade accuracy. LightLab applies liquid chromatography which separates the cannabinoids, spectroscopy which uses light to analyze the sample’s compounds and finally linear regression mathematics to calculate sample results.
HIGH PERFORMANCE LIQUID CHROMATOGRAPHY
Your analytical laboratory likely uses High Performance Liquid Chromatography (HPLC) to analyze your hemp or cannabis sample. Like an HPLC, LightLab pushes an extracted cannabis sample through a column. The column separates the cannabinoids in the sample by slowing down cannabinoids by different amounts based on their affinity to the column. This allows each cannabinoid to exit the column at a different time. For example, CBD may exit the column first, then D9THC and so on. Once the column separates the cannabinoids, they move to the next step in our analytical process: Spectroscopy.
Spectroscopy uses light to measure the analytical composition of compounds. During the analytical process the sample flows between a light source and a detector. The detector will quantify how much light is getting through the sample. Since every cannabinoid has a particular light absorption signature LightLab can provide quantitative measurements. LightLab borrows spectroscopy technology from the Curiosity Mars Rover, providing an accurate and dependable analysis every time.
LINEAR REGRESSION MATHEMATICS
In its most simple form, linear regression has its roots in the simple formula we all learned in high school, y = mx+b, the equation for a line. Linear regression takes this simple concept and applies it to millions of data points in order to accurately distill the information present in the chromatagraphs so you don’t have to. The results screen populates each cannabinoid weight percent in a simple, easy-to-read report.
