Cannabinoid Profiling by High Pressure Liquid Chromatography (HPLC)

This analysis includes: delta-8 THC, delta-9 THC, THCA, THCV, CBD, CBDA, CBDV, CBN, CBG, CBGA

Cannabinoid profiling (potency) testing via liquid chromatography is required for all products sold in California and includes moisture analysis. Many of our clients use HPLC testing to accurately dose their infused products, gauge 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 FDA BAM

Is my product clean? How many bacteria or fungi are present in my sample? Are there dangerous pathogens in my sample?

Just as with any other medicine or food product, 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 screen for all microbiological impurities required by the State of California including: Shiga-toxin producing E.coli,   Salmonella sp., Aspergillus flavus, Aspergillus niger, Aspergillus fumigatus, Aspergillus terreus, Pseudomonas aeruginosa, and coliforms. We also have the ability to test for aerobic bacteria, yeast, mold, and other contaminants in your medical Cannabis product.

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

Are there residues of pesticides or fungicides in my product?

The State of California requires all Cannabis products sold to be screened for residual pesticides. 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 in line with state mandates:   

Compliance Pesticide Category 1 Screening

  • Required as of 1/1/2018

  • 21 compounds with ZERO tolerance - there is no acceptable limit for these compounds

Combined Compliance Pesticide Category 1 & 2 Screening

  • Required as of 7/1/2018

  • 65 compounds - acceptable limits vary depending on compound and sample type (see BCC section 5719)

Terpene Analysis by GC-FID

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 tests and quantifies 19 different terpenes, including Myrcene, Limonene, Caryophyllene, and many others.

A comprehensive list can be found here.

Residual Solvent Testing via GC-FID

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 20 different solvents including all compounds of Category 1 & 2 Lists required for CA state compliance (BCC section 5718).


 

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. 

Homogeneity Testing

Is my product consistently dosed?

The State of California now requires all edible products that contain more than a single serving to undergo potency homogeneity testing every six months. Homogeneity testing involves taking many samples from the same product to ensure that cannabinoids are evenly distributed throughout the product, ensuring an accurate serving.
