THE HIGHEST STANDARDS WEREN’T AVAILABLE,
SO WE CREATED THEM.

The cannabis industry is a rapidly moving landscape. Sonoma Lab Works is continually evolving as new discoveries are made in the science of cannabis. Our testing procedures are regularly updated to stay on the cutting edge of sample analysis and maintain our reputation as Northern California’s best cannabis testing laboratory. Our dedication to precision and inter-lab collaboration to bring consistency across the board is unrivaled.

Sonoma Lab Works performs the following tests on flower, concentrate, edibles, and other cannabis products (MIP, topical, etc.)

Potency (Cannabinoids)

Sonoma Lab Works tests for 10 of the most predominant cannabinoids including THC, THC-A, CBD, CBN, and ∆9-THC. Growers and dispensaries in Northern California rely on our potency analysis for a full profile of cannabinoids with incredibly accurate results. Our Ultra Performance liquid chromatography (UPLC) techniques are the best in Northern California.

Terpene Profiling

As the science of cannabis moves forward, there is increasing evidence of the therapeutic benefits of terpenes. Plus, they make your products taste and smell great! We test for 20 of the most common terpenes found in cannabis, so you can have the most detailed profile of your product’s attributes including limonene, pinene, myrcene, linalool and B-Caryophyllene. We utilize gas chromatography in conjunction with Mass spectrometry (GC-MS) – the only method that can ensure an accurate and full readout of what’s in your product.

Pesticide Analysis

We currently test for all 66 pesticides for both Class I and Class II down to the levels needed for compliance testing. Our current capabilities allow for detection down to parts per trillion level (PPT), resulting in unparalleled screening abilities of raw material to ensure safety and consistency throughout the supply chain. This ensures that your product is free of harmful pesticides such as Bifenazate, Acequinocyl, and Trifloxystrobin. We examine by liquid chromatography and triple quadrupole mass spectrometry (LCMS/MS) for ultra-reliable results.

Mycotoxins

Mycotoxins are harmful chemical compounds produced by fungi as a byproduct of their metabolism. Contact with mycotoxins can be harmful to humans and even result in death. Molds that produce mycotoxins can grow on cannabis and cannabis products. Laws require screening for Aflatoxin and Ochratoxin both produced by several different aspergillus species. Mycotoxins are screened using LCMS/MS.

Heavy Metals

Heavy metals can present in cannabis if they are present in the soil or water. These metals can be highly toxic even in low amounts. Inhalation or consumption of these metals can have significant health impacts on consumers. Testing for heavy metals is a Phase III requirement and is mandated as of January 1, 2019.

Microbiological Contaminant Identification

Cannabis is rarely cultivated in a sterile environment. Instead, it’s grown in places with a full range of microscopic life that contribute to the quality of the product produced. Given that the standard culturing methods for microbial screens have many issues with validity and accuracy, we have invested significant resources in equipment using quantitative polymerase-chain reaction (qPCR) to test for microbial contaminants to ensure the accuracy and validity of the results.

Residual Solvent Quantification

Concentrated cannabis must be free of many toxic substances to ensure consumer and public health safety. We utilize gas chromatography in conjunction with Mass spectrometry (GC-MS) the only method that can ensure an accurate identification and quantification of what’s in your product down to the detection limits required by the state.

Genetic Testing

StrainSEEK (genetic sequencing of plants):
-Whole Genome Sequencing | Determines genetic history and strain lineage. All data entered into DASH blockchain, serves as public record of prior use that can be used to defend against patent attempts, such as US Patent US9095554B2.
-Genetic Markers | Covers multiple cannabinoid/terpene synthase genes. Helps breeders and cultivators identify genetic markers for desirable traits, such as predisposition to produce certain terpenes and cannabinoids.

New, Expanded Genetics Testing (test for gender or specific dangerous viral/bacterial/pest to cannabis):
-Gender Detection | Used to tell male from female plants. Female plants produce cannabinoids while male plants do not. This test can determine gender earlier than a visual inspection. This test is more accurate then seed sexing.
-Botrytis | Botrytis cinerea, a mold that infects the bud of plants. This mold can be spread through seeds to an infected plants offspring. Infection may be symptomless allowing the pathogen to spread without detection.
-Powdery Mildew | Destructive fungal infection. Allows for early detection before the plant is visibly infected. Typically emerges 2 weeks into flowering.
-Fusarium | This soil fungus is common in many areas and most species are harmless to the plant. Some species can cause damage to the plant by infecting the vascular system. Early detection is key in preventing the spread of this fungal pathogen.
-Russet Mites | These biological pests feed on the plant resulting in a decrease in resin production. Russet mites can be difficult to detect using visual inspection alone.
