Hemp & CBD Testing Services

Potency

Potency testing measures not only the presence or detection of specific cannabinoids (fingerprinting) but the quantity or concentration of these naturally-occurring chemicals.  Potency is related to the efficacy or strength of a chemical in the plant or cannabis-infused product. Our analysis utilizes chromatographic techniques High-Pressure Liquid Chromatography-Ultra Violet absorption (HPLC-UV) after the plant material or infused-product has been carefully processed and cannabinoids extracted.

Our potency test measures 12 cannabinoids (THCA, THC Δ8 & Δ9, THCV, CBDA, CBD, CBC, CBGA, CBG, CBN, CBDV and CBDVA) in a sample.

Metals

Metal testing measures the amount of selected ion metals in plant material, foodstuff, soil, and water. Metals can be necessary for the functioning of organisms (for example, iron in blood) including us humans, or can be harmful to our health (for example, lead in paint or mercury in fish). Cannabis plants including Hemp are notorious for naturally extract contaminants from the soils where they are cultivated.

Our metal testing comprises the analysis of the “CLAM” group (C = Cadmium, L = Lead, A = Arsenic, and M = Mercury) using ICP-AES (Inductively Couple Plasma Atomic Emission Spectroscopy). Our methods are ISO 17025 and NELAP certified.

Pesticides

A pesticide is a substance utilized to kill, repel, or control organisms (plant or animal) that are pests to crops or other animals (for example mice, rats). There are different categories of pesticides such as;

  • herbicides (used for destroying weeds and other undesirable vegetation),
  • insecticides (used for managing or controlling certain insects),
  • fungicides (prevent the growth of molds and mildew),
  • disinfectants (for preventing the spread of bacteria), 
  • and compounds used to control other pests (for example mice).

We analyze a total of 66 analytes utilizing Liquid Chromatography-Mass Spectrometry/Mass-Spectrometry or LC tandem mass spectrometry (LC-MS/MS, LC Triple Quad uses two mass analyzers), but we can also analyze some pesticides using GC-MS/MS (GC Triple Quad).

Terpenes

Terpenes are naturally occurring compounds and are primarily components of essential oils. These compounds give aroma and flavor to all plants including Hemp. These chemicals are produced by the plants to protect them from being consumed by organisms such as insects. Our lab conducts both fingerprinting (determines which terpenes are present) and profiling (amounts or concentrations in which these compounds are present). Our terpenes testing uses Gas Chromatography-Mass Spectrometry (GC-MS) to identify and quantify these compounds.

We test for 21 terpenes in hemp plant material or oils and manufactured products (for example lotions, baked goods, gummies).

Residual Solvents

Chemical solvents (for example isopropyl alcohol, ethanol, acetonitrile) are used to extract other compounds such as cannabinoids or terpenes during manufacturing processes to increase the yield and concentrate the material of interest. These solvents can be very harmful if they are consumed or inhaled. Analysis of these solvents in manufactured oils, tinctures, ingestible, or other infused products is extremely important and products need to not contain trace or residual amounts of these detrimental compounds.

Our lab analyzes 20 Cannabis-based residual solvents using GC-MS and headspace methodologies.

Mycotoxins

Mycotoxins are the toxins found in molds and fungi; these are basically the by-products of these pathogens. Hemp can be contaminated during processing, manufacture, transportation, or storage. Warm and humid conditions promote the growth of these pathogens and upon consumption. These can be extremely harmful to human health or that of pets if, for example, a dog ingests a contaminated dog treat or biscuit-infused with CBD.

A total of 5 mycotoxins tested using LC-MS/MS.

Microbials Screening

Pathogenic bacteria are microbes (for example salmonella, E. coli, Aspergillus) that can cause very serious diseases (for example diarrhea, respiratory problems). Hemp and processed infused products can be contaminated during processing, manufacture, transportation, or storage.

Our testing uses sensitive molecular biology techniques, polymerase chain reaction (PCR) technology to screen for the presence or absence of these pathogenic bacteria.
