TestingTesting

Giving your head a rest
Everyone rests easier when they
feel safe. And safety comes
through testing.

Our hallmark is cannabis testing and quality-control services. This is due to our industry-leading chemists and microbiologists who use validated methodologies and state-of-the-art equipment. We not only help you achieve regulatory compliance, we can support you in understanding the complexity of medical cannabis and products for adult use.

Potency testing

We offer unparalleled sensitivity and selectivity in determining product potency, including THCA/THC and CBDA/CBD levels and their total equivalents. This analysis can be performed on fresh or dried cannabis flowers (buds), extracts, oils, and concentrates. If you’re interested in product forms beyond these, please contact us.

Our in-house validated methods are compliant with ICH Q2 analytical method validation guidelines.

We’ve earned Emerald Badges for potency testing every year since we started proficiency testing in 2016.

Microbial contaminants

We offer full microbial analyses for these tests required by Health Canada:

  • Total yeast and mould
  • Total aerobic microbial counts
  • Bile-tolerant gram-negative bacteria
  • E. coli
  • Salmonella spp.

We also offer analyses on the following:

  • S. aureus
  • P. aeruginosa

We can perform the following tests according to compendial methods: Ph. Eur. 2.6.31, Ph. Eur. 2.6.13, or USP 62: Please let us know which you prefer.

We’ve earned Emerald Badges for all our required microbial tests.

Aflatoxin analysis

Our validated method for aflatoxin B1 is compliant with EP 2.8.18 (aflatoxin B1 2.0 ppb limit). And to get really technical, it employs immunoaffinity column chromatography followed by UPLC-MS/MS analysis to quantify aflatoxin B1. But we scan for total aflatoxins – B1, B2, G1, and G2.

Metal analysis

Cannabis has been shown to accumulate heavy metals from substrate, water, or fertilizers if they contain metals. As regulations require, we test for arsenic, cadmium, lead, and total mercury levels in cannabis flowers and extracts.

If you’re interested in looking at micronutrients to guide production, you can also request testing for the following 27 metals:

  • Aluminum (Al)
  • Antimony (Sb)
  • Barium (Ba)
  • Beryllium (Be)
  • Bismuth (Bi)
  • Boron (B)
  • Calcium (Ca)
  • Chromium (Cr)

  • Titanium (Ti)
  • Uranium (U)
  • Vanadium (V)
  • Zinc (Zn)

Pesticide screening

You can test for 51 different pesticides, fungicides, and plant-growth regulators (PGRs) by choosing our pesticide screen, which has been awarded an Emerald Badge every year since 2016.

When testing cannabis flowers and oils, this screen uses UPLC with tandem mass spectrometry detection (LC-MS/MS). It can provide confirmation down to single digit part per billion (ppb) concentrations for most pesticides.

These are the pesticides, fungicides, and PGRs included in our screen:

  • Acetamiprid
  • Aldicarb

  • Diazinon
  • Dichlorvos
  • Dimethoate
  • Ethoprophos
  • Etofenprox
  • Etoxazole
  • Fenoxycarb
  • Fenpyroximate

  • Methiocarb
  • Methomyl
  • Myclobutanil
  • Oxamyl
  • Paclobutrazol
  • Phosmet
  • Piperonyl butoxide

  • Spinosad D
  • Spiromesifen
  • Spirotetramat
  • Spiroxamine
  • Tebuconazole
  • Thiacloprid
  • Thiamethoxam
  • Trifloxystrobin

Loss on drying

Required by Health Canada for all dried cannabis products, our loss on drying (LOD) test provides the moisture content of your sample. It’s included in our full package, or you can request it as a standalone test.

Residual solvent analysis

We have developed and validated a test to identify the presence of the following residual solvents in concentrated or formulated forms of cannabis oil/extracts:

  • Methanol
  • Ethanol
  • Acetone
  • Isopropanol (isopropyl alcohol)
  • Acetonitrile
  • Hexane
  • Heptane
  • Pentane

We use headspace analysis and GC/MS to identify the solvents and trace residues of chemicals from the extraction process.

Foreign matter

When we receive samples for full-package testing, we visually examine them for any foreign matter that may be present. Typically not offered as a stand-alone test, but included as an added value when you request full-package testing.

Sex ID

If you’re a cultivator looking to evaluate new genetics from seed, we’ve developed a novel DNA-based assay for quickly and accurately determining the sex of cannabis seedlings. Using leaf samples, we efficiently screen your plants so you can use your space more effectively and accelerate your breeding activities.

This test is proprietary, and we have filed for patent protection on it.

Predictive Profiling

Using early seedling leaf tissue, we can perform a cannabinoid screen for all 14 cannabinoids. This assay has proven to predict overall ratios of THC and CBD equivalents and provides more information for breeding and selection purposes.

We’re working on a similar assay for terpenes, so keep an eye out for that.

Cannabis testing for patients

If you’re authorized to grow cannabis by Health Canada (ACMPR or MMAR/Injunction), we’re happy to help with any testing you’re interested in. We find most patients test for potency, cannabinoids, or terpenes, but the whole suite of tests is open to you.
