Why analyze your CBD products? 

Hemp is a genetically diverse plant grown under many different conditions and is a known bioaccumulator of contaminants. It is therefore necessary to test hemp and hemp derivatives to uphold the standards that we expect of therapeutic products.


CBD quality certification with Stillwater Labs of Montana includes tests that confirm:

  • Potency
  • (cannabinoid content)
  • Terpenes
  • Product cleanliness
Rule out:

  • Pesticides
  • Mycotoxins
  • Microbes and Molds
  • Residual Solvents
  • Heavy Metals


These aspects of CBD quality ensure safe and reliable products for your clients and their customers.

Reports and Product Labels
Your fully tested product will receive an electronic certificate of analysis (CoA). Your data is stored on encrypted servers and is available for you to download at any time.

Notes on Farm Bill Hemp
“Farm Bill” designation is a special classification of cannabis that is permitted by the US and state Departments of Agriculture. This dispensation allows the cultivation, processing, and sale of hemp and hemp products. Farm Bill hemp may currently be transported via US Post but may require registration and a pro- forma disclaimer. Please contact us for sample containers, shipping kits, and current guidelines.

Over 150 phyto-cannabinoids have been identified to date (CBD and THC are two of the better known), and the presence of these in hemp varies by plant variety, the environment, the time of harvest, and post-harvest conditions. Concentrate potency also changes considerably depending on the extraction method and degree of refinement. Stillwater Labs uses HPLC (high performance liquid chromatography) to provide an eleven-analyte cannabinoid profile

Terpenes are the natural compounds that provide flavor and character in hemp and other plants. At Stillwater Labs, the Terpene Profile is generated using a GCMS (gas chromatograph with a mass spectrometer detector) to capture and identify volatile and aromatic terpene compounds.

Extraction methods provide a more controlled concentration of cannabinoids and terpenes. Extraction products should be tested for residual solvents to ensure safety. At Stillwater Labs, solvents are detected using a GCMS to capture, identify, and quantify analytes.

Pesticides are agricultural tools that allow the grower to maximize yield and character of hemp, but pesticides may be toxic if they remain in the product. Stillwater Labs uses an LCMSMS (ultra- high performance liquid chromatography with a triple quad mass spectrometer detector) to quantify common pesticides as referenced in the AHP Cannabis Inflorescence Quality Control Monograph, 2014 and those recommended by state cannabis programs.

Microbes and molds are common in nearly all agricultural products due to natural dispersal in our environment. Most of these are of no concern, but some are known pathogens and may pose a health risk. Stillwater Labs uses a well-validated commercial method to identify E. Coli, Salmonella sp., and common molds.

Mycotoxins are Class 1 carcinogens produced by some fungi and molds. Stillwater Labs uses an LCMSMS to identify mycotoxin contamination.

Hemp is an accumulator plant via the root system, absorbing heavy metals that may be present in the soil, fertilizer, or water. Stillwater Labs uses an ICPMS (inductively-coupled plasma with a mass spectrometer detector) to precisely determine concentrations of arsenic, cadmium, mercury, and lead.
