CBD testing

The term CBD is an abbreviation of cannabidiol, one of the many chemical compounds that are found in cannabis and hemp plants. The sale of CBD products has increased remarkably in the last couple of years and their diversity has increased accordingly, spanning a variety of forms including oils, food supplements, cosmetics and e-cigarette liquids.

Whilst cannabis contains many active compounds, it is tetrahydrocannabinol (THC) which is responsible for the majority of the plant’s psychoactive properties. In the UK, CBD products must contain less than 0.2% THC to be legally compliant. Products containing THC in excess of 0.2% are governed by the Misuse of Drugs Act, with all the legal ramifications that implies.

Accurate analysis of CBD products is critical to maintaining compliance with legislation governing potency, content and quality; in addition to ensuring safety around contamination with pesticides, heavy metals, mycotoxins and biocides.

a1 envirosciences has a wide range of analytical instrumentation with applications in testing CBD raw materials and finished products.

Karl Fischer

Moisture can be extremely detrimental to the quality of stored CBD products. Our range of Karl Fischer instruments provide a highly sensitive and accurate solution for testing moisture content of oils, leaves, resins and creams, even down to trace levels.

Mercury Analysis

As cannabis and hemp plants grow, they absorb metals from the soil, including mercury, exposure to which is potentially harmful to human health. a1 envirosciences has a range of mercury analysers ideal for assaying a huge variety of matrices for mercury.


Sample preparation prior to analysis can present laboratories with severe process bottlenecks, significantly slowing turnaround times and taking laboratory staff away from other more profitable work. a1 envirosciences’ laboratory automation solutions can make sample preparation (for example dilutions for ICP) faster and more consistent, enabling you to get the maximum potential from your analytical instruments.
