Comparative Study of Moisture Analysis Techniques on Cannabis
Summary
Moisture in cannabis impacts potency and must be accurately determined. Loss on drying (LOD) is the most popular method for determining moisture in cannabis. Unfortunately, this technique is not specific to moisture and the loss of any volatile components, such as terpenes, will be incorrectly classified as moisture. Karl Fischer (KF) titration is the only chemically specific test for moisture. This poster describes the instrument used to determine moisture content by Karl Fischer titration and compares the results of this data to loss on drying.
