Accredited Cannabinoid Testing
Our ISO 17025 Accredited laboratory tests for 14 different cannabinoids including THC and CBD to provide a broader spectrum of products
In our pursuit of excellence, we take the pharmaceutical approach to CBD testing. Testing is performed in our ISO 17025 accredited laboratory – our equipment is regularly calibrated and validated both internally and externally for complete quality assurance. Every step in our CBD testing is fully documented and standardised to give more accurate and reliable results.
We test a wide range of products for 14 cannabinoids including THC: CBDV (Cannabidivarin), CBDVA (Cannabidivarinic acid), CBG (Cannabigerol), CBD (Cannabidiol), THCV (Tetrahyrdocannabivarin), CBDA (Cannabidiolic acid), CBGA (Cannabigerolic acid), CBN (Cannabinol), Δ9-THC (Δ9-tetrahydrocannabinol), Δ8-THC (Δ8-tetrahydrocannabinol), THCVA (Tetrahydrocannabivarinic acid), CBC (Cannabichromene), THCA (Δ9-tetrahydrocannabinolic acid), and CBCA (Cannabachromenic acid)
HPLC is a technique in analytical chemistry used to separate, identify and quantify compounds in mixtures. How HPLC works: Each cannabinoid has a slightly different chemical structure, similar but different. HPLC works by forcing the mixture through a column. A column is a tightly packed bed of very small inert beads. Due to the differences in chemical structure, and hence their physical shape, the different compounds travel through the column at different speeds. By applying a constant pressure and temperature to the chemicals being forced through, you can record the retention time of each chemical as it passes through.
At the other side of the column is a detector – this gives you a signal as something comes out of the column. The more of something that comes out, the stronger the signal. So, by combining these two effects, you know at what time each compound come out – and from the strength of the signal how much of each compound is present – that is the basis of HPLC.
We train the system by putting standards for each compound through the system. These standards are very high purity chemicals and allow us to calibrate the system and tighten the accuracy of our results.
We pioneered testing-in-triplicate for CBD products – a product is sampled three times before the results are pooled into a single-average figure. Every sample is double injected – each individual sample goes through our equipment twice.
Making science simple: Each sample is tested six times to reduce the variability of results – this allows us to identify rogue results with greater ease. We are also able to test closer to legal limits with greater accuracy.
If only a single test is performed, the result maybe unstable and inaccurate, or a rogue reading may occur. This means the tests must be repeated causing further delay and expenditure.
Cannabinoid standard tests: isolate/distillate, CBD oil, e-liquid, cosmetics, CBD paste, drinks, water soluble CBD, capsules, edibles (gummies, chocolates etc), tea, coffee beans, any other food produce.
Our other testing includes: full cosmetic testing & notification on EU portal, terpenes, solvents, GPSR compliant emissions testing, heavy metals, pesticides.
Our gold standard service is no more than a single sample testing. Once testing has been concluded, a formal certificate is issued. Our commitment to high pharmaceutical standards provides results that our clients can rely on and trust.
The cannabidiol (CBD) market is governed by wide-ranging global regulations. Here are some key legal aspects:
