We determine the potency and profile of many naturally occurring cannabinoid compounds by High Performance Liquid Chromatography (HPLC). This testing helps determine exact concentrations of THC, CBD, and many others.
Hemp is tested for heavy metals to quantify contaminants such as arsenic, lead, cadmium, and mercury. Inductively Coupled Plasma with Mass Spectrometry detection (ICP-MS) provides very specific and accurate results.
The taste and aroma characteristics are determined by Gas Chromatography with Mass Spectrometry detection (GC-MS). Terpene profiles are important to understand the different strains of cannabis and to ensure that they are not being removed from processing of the hemp plant.
Moisture content generally refers to the amount of water in the plant. Hemp plants need to be dried properly for long term storage. This testing is generally performed by a small moisture meter that can determine the percentage of water in the plant material. The result can also be used to correct cannabinoid results to a "dried basis".
