Most states mandate that cannabis-testing labs analyze samples for
any fungal or microbial growth, resulting from production or handling, as well as mycotoxins, which is a class of toxins produced by fungi. With the potential to become lethal, continuous exposure to mycotoxins can lead to a buildup of progressively worse allergic reactions.
The best way to analyze the moisture content of any product is the thermo-gravimetric method. This process involves placing the sample of cannabis into the sample chamber and taking an initial reading. Then, the moisture balance will heat up until all the moisture has been evaporated out of the sample. A final reading is then taken to determine the percent weight of moisture that was contained in the original sample.
There is no prep, simply place the sample in the balance.
