Only compounds above 0.05% of any given solution are able to be detected accurately with modern analytical machines, below these levels, “in analytical chemistry, [the] lower limit of detection, or LOD (limit of detection), is the lowest quantity of a substance that can be distinguished from the absence of that substance (a blank value) with a stated confidence level (generally 99%)” (en.wikipedia.org), but still remain in our extracts at trace levels. The most common techniques used for analysing the cannabinoids in hemp extracts, are high-performance liquid chromatography (HPLC; formerly referred to as high-pressure liquid chromatography), and gas chromatography.
