Cannabis FAQ’s

What cannabinoids do you test for?

We currently quantitate the following cannabinoids: d9-THC, THCA, CBD, CBDA, CBN, CBG, THCV, and CBC. As more validated cannabinoid standards become available we will be adding them to our potency profile.

What terpenes do you test for?

For Cannabis products we specifically look for the following terpenes: α-pinene, myrcene, linalool, limonene, terpinolene, β-caryophyllene, humulene and α-bisabolol.  However, because we use mass spectrometry we can identify and report the relative abundance of thousands of different small terpenoid molecules depending on your need.

How do you screen for microorganisms and what organisms do you screen for?

We use a rapid plating technique using growth media which is specific for the organisms we screen for.  Samples are run in triplicate against a control plate to ensure accuracy and results usually take about 48 hours, but you can be sure that the results represent actual live organisms and not just residual DNA.  We test for all organisms as required by I502, namely: Yeast and mold, Enterobacteriaceae (bile-tolerant gram negative bacteria), Coliforms, E. coli, Salmonella and total aerobic bacteria.

What residual solvents can you detect?

Because we use mass spectrometry in conjunction with a NIST database for residual solvent testing we can detect and identify pretty much any solvent that might remain in your product.  For solvent extracted Cannabis products we commonly observe the following residual solvents: propane, butane, iso-butane, pentane, ethanol, acetone, methanol, ethyl acetate and hexane.  Other oxidation products (i.e. acetaldehyde from ethanol) may also be observed depending on how your product is manufactured.
