Cannabinoid Profiling by High Pressure Liquid Chromatography (HPLC)

This analysis includes: delta-9 THC/THCA, THCV, CBD/CBDA, CBDV, CBN, CBG/CBGA, CBC 

Cannabinoid profiling (potency) testing via liquid chromatography is recommended for products that will be ingested in a raw or unheated form, infused products, and for concentrate producers looking to test the completeness of their decarboxylation process. This method uses solvents rather than heat during the analysis, allowing for detection of non-psychoactive, acidic Cannabinoids like THCA, CBDA, and CBGA, which form THC and CBD when heated.

Microbiological Analysis via petrifilm

Is my product clean? Are there dangerous pathogens in my sample?

Just as with any other medicine or product in our food chain, Cannabis must undergo quality assurance testing to ensure its cleanliness and safety - especially for the very young, elderly, and those who are immunocompromised. 
CW Analytical has the experience and capability to test for aerobic bacteria, yeast, mold, E. coli, Pseudomonas aeruginosa, Salmonella, and other contaminants in your medical Cannabis product. 


Chemical Residue (Pesticide) Testing by LC-MS/MS

Are there residues of pesticides or fungicides in my product?

There are currently no EPA approved pesticides for Cannabis produced in the U.S or California. Many pesticides can be harmful for human consumption, and some pesticides commonly found in Cannabis are only approved for ornamental plants. 
CW offers two options for chemical residue testing. Our routine analysis provides quantification of 20 common pesticides, and our expanded analysis provides quantification of 56 chemical compounds and aflatoxins. A list can be found in our FAQ.

Terpene Analysis by GC-MS

What compounds are contributing to the smell or flavor profile of my sample? What are the concentrations of terpenes in my sample?

Terpenes are a specific class of organic chemical compound found in Cannabis that contribute strongly to the smell and flavor of the flower, but may also have additional medical benefits.
CW currently tests and quantifies 33 different terpenes, including Myrcene, Limonene, Caryophyllene, and many others.

A comprehensive list can be found in our FAQ. 

Residual Solvent Testing via GC-MS

Is my sample free of residual solvents leftover from extraction? (e.g. Butane, Propane, Alcohol)

Many Cannabis concentrate producers utilize a variety of solvents to manufacture high-quality, potent, waxes and oils. While many of these commonly used solvents (ethanol, isopropyl, butane, propane) carry G.R.A.S status (generally regarded as safe) it's important to understand the constituents of any product patients are consuming. 
CW can currently quantify the concentration of 14 different solvents common in concentrate production, including Butane and Ethanol.


Nutrition Facts Labels

What is the nutritional value of my edible? (e.g. calories, fat, sugar, carbohydrates, etc.)

Patients deserve to know the ingredients and nutritional impact of any infused Cannabis product they are going to consume. Our technical team is capable of creating a legal nutrition facts statement and allergen statement, just like those you'd find on any standard food product in a grocery store. 

Mixing Charts for Edibles

How much Cannabis do I need to add to achieve my desired edible potency?

Consistently hitting the desired potency mark on an edible can be difficult without proper information about the Cannabinoid content of the the raw product  (i.e. infused butter, oil, kief). Even if a concentrate, butter, or oil is made "the same way every time," the potency will differ from batch to batch. CW Analytical offers mixing charts for our clients who produce edibles to better ensure that they can hit their target potency every batch.


If you have further questions or needs beyond our suite of tests, we're glad to help!

Sometimes the needs of our clients go beyond what our typical tests can provide, and that's perfectly fine. CW Scientists have decades of experience in the food sciences, microbiology, chemistry, and Cannabis, and can help you refine and optimize your product.  If we have the capability to help, we will! Contact CW Analytical to inquire about consultations and our hourly rate.

Phylos Biosciences Genetic Testing

What is the sex (male/female) of my cannabis plant?

Our partnership with Phylos Biosciences allows us to offer plant sex tests, enabling growers to determine whether a Cannabis plant is male or female as early as seven days old.
