CBD Products Testing

  • Accurate analysis of CBD products is essential to ensure they meet required levels of quality and potency and there are no safety concerns in respect to pesticides, mycotoxins, heavy metals and microbial contamination.

CBD Products Testing

The term "CBD" is an acronym for cannabidiol, which is one of several cannabinoids, or chemical compounds, that are found in cannabis and hemp plants. CBD product sales have significantly increased in the last 3 years, primarily for perceived health and wellbeing effects. CBD oil can be used as a food ingredient, sometimes blended with other cooking oils. The oil can also be heated and its vapours inhaled. CBD products come in many forms including cosmetics and food supplements. Tetrahydrocannabinol (THC) is the active chemical in cannabis and is one of the oldest hallucinogenic drugs known. 


Current Home Office guidance states that for CBD products to be legal in the UK the hemp plant must produce less than 0.2% THC, and there should be less than 1 mg (THC) in any subsequent container of CBD oil or product that is sold.

Our Services 

Fera have developed an analytical method using High Performance Liquid Chromatography (HPLC) instrumentation that can screen and quantify cannabinoids at low concentrations (parts per million) within a variety of CBD products.

Applicable product types include CBD oil, cream, capsules, vape oil/juice and chewable sweets as well as hemp derived food products such as hemp oil, seeds and protein powder. Please contact us if you are unsure your product is applicable for our methodology.

Potency Testing (7 Cannabinoids - Full Suite)

Potency is assessed by determining up to 7 cannabinoids (we analyse for CBD, CBDA, CBC, THC, THCA, CBG and CBN) in the sample. Using HPLC our current Limit of Quantification (LOQ) is 70 mg/kg (per individual compound) in CBD oil. Please enquire for LOQs in other matrices. For THC testing only, a Gas Chromatography-Mass Spectrometry (GC-MS) method may be used with a LOQ of 0.005 mgkg-1.

Heavy Metals

It is known CBD oil may accumulate heavy metals. Using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) our methods quantify arsenic, lead, cadmium and mercury (other metals on request) with LOQs of 0.01 mgkg-1 in CBD oil.
