Cannabis testing methods


Accu­rate potency results are crit­ical for final product formu­la­tions, defining safe dosages and legally defen­sible label claims.
Your product and busi­ness repu­ta­tion depends on accu­rate potency results.

  • Potency- Basic Profile (all regu­lated cannabinoids)
  • Potency- Extended Profile (includes over 25 cannabinoids)
  • Potency- Arti­fi­cially Derived Cannabi­noids Profile (ADCs)
  • Potency- High Purity: Pure prod¬ucts (>95%) such as Isolates and Terpenes.
We prove our accu­racy and preci­sion through third party profi­ciency testing. Our best-in-class method­olo­gies, coupled with the most powerful instru­ments avail­able bolster our clients with legally defen­sible results, every time.

  • Imida­zoli­none Herbi­cides;​“imi” type of herbi­cides such as Pursuit®, Arsenal®, Scepter®, Raptor®, and Cadre®.

Residual Solvents

When solvents are used to extract cannabi­noids and terpenes from the plant mate­rial, the residual mate­rial left in the prod­ucts is regu­lated with action levels to ensure safe consump­tion and inhalation.

  • Residual Solvents – Oregon: regu­lated list
  • Residual Solvents – Cali­fornia: Cat 1 and Cat 2 testing, CA MRLs
  • Residual Solvents – Health Canada: avail­able for Terpenes extracts and infused products

We offer several residual solvent profiles so you can ensure the product is compliant, impu­rity-free, and made with a high-quality process that purges impu­ri­ties by testing for Residual Solvents.

Heavy Metals

Metals can be intro­duced at many control points and are carcino­genic at certain levels. Cannabis absorbs metals from soil, air and water, may become cont­a­m­i­nated during processing.

We test for metals using ICP/MS. We offer testing in many different types of samples including water, soil, extracts, topi­cals and edibles at very low levels of detec­tion, to ensure consumer safety.

  • Heavy Metals Profile: Arsenic, Cadmium, Mercury, Lead
  • Minerals


Molds that produce myco­toxins are present in many crops, from nuts to coffee beans to cannabis.
We offer myco­toxins profile that hit any state require­ments for cannabis as well as an expanded profile that goes beyond current regulations.

  • Afla­toxin B1, B2, G1, G2
  • Deoxyni­valenol (DON)
  • Fumon­isin B1 & B2
  • Ochra­toxin A & B
  • T‑2 & HT‑2 Toxins
  • Zear­alenone (ZON)

Terpene Profiling

Terpenes give cannabis it’s distinc­tive flavor and aroma. These compounds may enhance cannabis prod­ucts’ effec­tive­ness and define quality.

Columbia Labs tests for terpenes using GC/MS, show­casing your prod­ucts with a 40-terpene profile.


Columbia consis­tently scores at or near 100% in micro­bi­ology profi­ciency testing from the Amer­ican Profi­ciency Institute.
