Potency Analysis – 17 cannabinoids
Knowing the potency of your cannabis product will help in the determining the dose a patient will need to take. Using our HPLC instrument Pure Labs will test for and quantify the following cannabinoids: ∆-9 THC, THCA-A, THCV, THCVA, CBDA, CBD, CBDV, CBDVA, Delta 8 THC, CBC, CBCA, CBG, CBGA, CBN, CBNA, CBL, CBLA in cannabis flower, concentrates/extracts and cannabis infused products.
Moisture Content of Flower and biomass. – The ideal moisture content will keep fully cured cannabis buds from drying out and dry enough to prevent Microbial growth.
Water activity is measurement of the availability of water that is needed for microbial growth. Water activity below established thresholds will prevent microbial growth from occurring. Test can be performed on cannabis flower, concentrates/extracts and cannabis infused products.
“Water and microbial contaminants go hand in hand. The presence of mycotoxins such as fungi, mold, and mildew in cannabis can be dangerous if ingested, especially for people who suffer from existing medical conditions or have a compromised immune 41b9c2system.
Microbial contamination is mainly a risk during cultivation, but it can also occur during handling and packaging, due to poor hygiene practices from staff. Although mold and fungus are the main concerns, bacteria like Salmonella and E. Coli can also be present and are dangerous if ingested.” (Leafly)
Microbial testing below requires separately packaged samples.
Pure labs, LLC Utilizes PCR Microarray technology to detect the presence of contaminants such as E.coli, Salmonella and four pathogenic species of Aspergillus down to 1 CFU. This will provide a detected or not detected report.
Residual solvents are what can be left behind after extracting cannabinoids and terpenes from plant materials. Sometimes these solvents (such as butane, ethanol, CO2, and propane) are not entirely removed through the extraction process and can be harmful to our Arizona Medical Marijuana patients of the products. (i.e wax, hash oil, RSO, hemp oil, shatter, amber glass, crumble, budder, etc.)
Using our GCMS-HS instrument we will test for and quantify the following Residual Solvent:
|ethylene oxide||acetonitrile||ethyl ether||methanol|
|methylene chloride||butane (C4),||heptane||n-hexane (C6)|
Foreign Material inspection
Pure Labs LLC performs stereoscope analysis to inspect hemp/marijuana flowers and plant material for foreign-matter contamination.
Foreign material includes hair, insects, feces, packaging particles, and manufacturing by-products. This is a pass or fail test, with limits set by the Great State of Arizona.
Terpenes are the flavoring and fragrance of the cannabis plant.
Using our GC/FID instrument Pure Labs will test for and quantify 21 different Terpenes in cannabis flower, concentrates/extracts and cannabis infused products.
The terpenes tested for are the following:
|alpha-Pinene||delta-3-Carene||Ocimene 1 and 2|
During cultivation, plants can be exposed to a range of pesticides and other chemicals, like artificial growth hormones, that can be dangerous for a consumer to ingest. (Leafly). Pure Labs test for the pesticides directed by the Arizona Department of Health and Safety.
Heavy Metal testing
Heavy metals such as Arsenic, lead, mercury, and even cadmium can make their way into cannabis products. These substances can be present in soils and nutrients and can be absorbed by plant roots, and carried through to harvesting and processing. (Leafly). Pure Labs test for the heavy metals directed by the Arizona Department of Health and Safety.
