Our potency testing offers a quantitative analysis which includes a large list of compounds where we utilize advanced instrumentation and methodology to establish the exact concentration of unique analytes in any sample type. We use validated scientific methods along with an array of chromatographic instruments for the quantification of these analytes. Continuous development of new methods to test new compounds, along with optimizing the performance of our current methodology is always at the forefront of our focus.
Pesticide residues are analyzed by using a combination of LC MS/MS and GC MS/MS. The use of pesticides in agriculture is not new. Pesticide use on Cannabis, Mushrooms, and other nutraceutical crops is no exception. These harmful compounds usually are found in trace amounts in plant material destined for manufacturing. When lab testing the starting plant material, the results can often come back below the limit of detection (LOD) for pesticides even with the most advanced instrumentation. Often when the starting plant material is extracted and manufactured into products, the concentration of the active ingredients in the plant material can also concentrate the amount of pesticides from below the limit of detection, to a detected pesticide in your product.
Residual solvents can be found in concentrates and extracts. Solvents (i.e. water, carbon dioxide, ethanol, etc.) are used to extract the active ingredients from starting materials and are nearly impossible to completely remove from a final product. These solvents are highly flammable and proven extremely dangerous during the manufacturing of concentrates and if taken by a consumer in a product not purged properly it can cause severe medical issues. Headspace-Gas Chromatography with a Flame Ionization Detector (GC/FID), is an established scientific methodology that we use in the analysis for the separation and quantification of residual solvents.
Heavy Metal screening analyzes metals such as lead (Pb), mercury (Hg), arsenic (As), cadmium (Cd) and even chromium (Cr) utilizing an ICP MS/MS and microwave digestion for analysis.
Our test of sample material for filth and foreign matter which includes inspections for mold, sand, soil, cinders, dirt, hair, insects, feces, packaging contaminants and manufacturing waste and by-products.
Microbiological screening includes the detection of Aspergillus (A. niger, A. terreus, A. fumigatus, and A. flavus), Shiga toxin-producing E. coli, and Salmonella. Micro organisms Can be an indication of spoilage, levels of sanitation and the potential for human pathogens. Immunocompromised individuals are most at risk and can develop Aspergillosis, a condition caused by inhaling Aspergillus spores.
Mycotoxin screening analyzes for present toxins including Aflatoxin (B1, B2, G1, G2) and Ochratoxin A. Also under ideal conditions, some fungi can produce toxic metabolites known as mycotoxins (ex. Aflatoxin and Ochratoxin) which can infect immunocompromised humans and cause allergic, aflatoxin and pathogenic infections. Using Liquid Chromatography coupled to Mass Spectrometry quadrupole, we can quantify in parts per billion (ug/kg) the exact amount of Aflatoxin and Ochratoxin present.
Moisture and Water Activity analyzes solid and semi-solid products to determine its moisture and water-activity level. If the water activity is at or below 0.85 Aw, the sample “passes” water activity testing. Water activity at or above .85 Aw that is found in a product is an indicator that there are the ideal conditions for bacteria to grow and contaminate the product in the sealed package.

ISO is an acronym for the International Organization for Standardization. ISO/IEC 17025:2017 are requirements for the competence of testing and calibration of analytical laboratories and is the main ISO standard used by testing and calibration laboratories. In most major countries, ISO/IEC 17025:2017 is the standard for which most labs must hold accreditation in order to be deemed technically competent.
