A Beginner's Guide to Hemp Tests
As we have been talking with customers the question we get the most is "I have x type product, what all should I test for?". Below you'll find we put together a brief overview for each test we provide for hemp.
- Residual Solvents
- Water Activity/Moisture
What does a Potency Analysis include?
- delta 9-THC
- delta 8-THC
Why are Cannabinoids tested?
Why are Pesticides tested?
What does a Heavy Metals Analysis include?
Why is hemp tested for Heavy Metals contamination?
What does a Mycotoxin Analysis include?
- Aflatoxin B1
- Aflatoxin B2
- Aflatoxin G1
- Aflatoxin G2
- Ochratoxin A
Each analyte can be tested down to 1 ppb to give you highly accurate results.

What does a Residual Solvents Test include?
|2-Propanol (IPA)||Ethyl Ether||Tetrahydrofuran|
|Benzene||Heptane||1 n-butane and iso-butane|
|Butanes1||Hexanes2||2 n-hexane, 2-methylpentane, 2,2-dimethylbutane, 2,3-dimethylbutane|
|Cumene||Isopropyl Acetate||3 n-pentante, iso-pentane, neopentane|
|Cyclohexane||4 o-xylene, m-xylene, p-xylene|

What are Water Activity and Moisture tests and what do they include?
Why would you test for Water Activity/Moisture in hemp?
Water Activity Testing is recognized for its safety to cannabis edibles; it is also vital for the storage stability of harvested buds and extracts. Water Activity also controls the rate of decarboxylation that can lead to the breakdown of tetrahydrocannabinol (THC).
Many producers will test their products for moisture and/or water activity during the drying process to ensure they are getting to the appropriate level before storing. This helps reduce the risk of mycotoxins and microbial growth. These tests are also a common and essential test between the buying and selling hemp plants/biomass and smokeable hemp.
What does a Microbials test include?
Total Yeast and Mold: The total amount of live yeast and mold present per gram per sample tested (measured as colony-forming units per gram (CFU/g))
Salmonella: Presence/absence (pass/fail) test. Any trace of salmonella detected results in a fail
E. coli: Presence/absence test. Any trace of E. coli detected results in a fail
Total Aerobic Count: Total amount of bacterial contamination per gram per sample tested (measured in CFU/g)
Total Coliform: Total CFU/g per sample tested
Bile-Tolerant Gram-Negative Bacteria: Total CFU/g per sample tested
Why would you test hemp for Microbials?
Determining which tests you need for your product can be difficult. Along with the information above, it is great to always check with the potential buyers of your product, to verify what your minimum testing requirements should be. Many hemp businesses choose to do additional testing on top of those requirements to be used like an ‘insurance policy’ on your product. It gives proof that your product was not contaminated at time of sale. Many buyers of hemp will require more testing at the end of the process, and if the product tests positive, they will be looking who to put blame on.
