THE HIGHEST STANDARDS WEREN’T AVAILABLE,
SO WE CREATED THEM.
SO WE CREATED THEM.
Sonoma Lab Works has invested heavily in our equipment, including duplicate machinery, so we can turn around your test results in a timely manner. We will always tell you our current testing window, our average turnaround time is five days for compliance COAs.
Sonoma Lab Works utilizes high performance liquid chromatography (HPLC) to test for potency.
Sonoma Lab Works utilizes gas chromatography in conjunction with mass spectrometry (GC-MS) to provide terpene profiles for both R&D testing, and compliance panels (terpene testing is only mandatory for compliance testing if there are label claims).
Pesticide testing was introduced in the state of California in two phases, beginning January 1, 2018 (Cat I) and adding Cat II on July 1, 2018. Sonoma Lab Works tests for all Cat I and II pesticides indicated in the BCC’s compliance panels. Our current capabilities allow for detection down to parts per trillion level (PPT). We utilize liquid chromatography and triple quadrupole mass spectrometry (LCMS/MS).
Testing for mycotoxins is part of the BCC’s Phase 3 testing protocol. Mycotoxins are chemical compounds produced by fungi as a byproduct of their metabolism. Sonoma Lab Works utilizes liquid chromatography and triple quadrupole mass spectrometry (LC-MS/MS) for screening.
Sonoma Lab Works utilizes inductively coupled plasma mass spectroscopy (ICPMS), vs. AAS testing, as ICPMS is more sensitive and standard for fast multi-element determination of heavy metals in trace and ultra trace concentrations in different sample matrices.
Testing for microbial impurities became a mandatory part of compliance panels on January 1, 2018. Sonoma Lab Works has invested significant resources in equipment utilizing quantitative polymerase-chain reaction (qPCR) to quantify the accuracy and validity of results.
Residual Solvent Quantification
Residual solvents and processing chemicals testing was introduced in the state of California in two phases, beginning January 1, 2018 (Cat II) and adding Cat I on July 1, 2018. We utilize gas chromatography in conjunction with mass spectrometry (GC-MS) to detect levels for both R&D tests and compliance panels.
–Moisture Content Testing (Phase I): Moisture content testing is only required for cannabis flower to ensure that it was properly cured and cannot develop mold. We measure the difference of the sample before and after drying to determine percent of moisture.
–Homogeneity Testing Of Edible Cannabis Products: Homogeneity was originally required as part of Phase I, it is now no longer mandatory and is offered as an R&D test.
–Foreign Material Testing (Phase II): This requires a visual inspection of products for the presence of visible molds or foreign material. A simple light microscope is used to ensure no traces of surface mold in flower products.
–Water Activity Testing of Solid or Semi-Solid Edibles (Phase III): Water activity is a required test for cannabis flower and non-liquid edibles. The machine measures relative humidity after vapor pressure reaches equilibrium.
We are proud to work with Medicinal Genomics to offer StrainSEEK™ advanced testing of cannabis plants.
–Whole Genome Sequencing: Determines genetic history and strain lineage.
–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.

Research + Development
Research and development (R&D) testing is not mandatory and R&D test results are not made available to the BCC. However, it is an incredible tool to garner insight and data. Sonoma Lab Works originated as an in-house lab for CannaCraft, so we understand the critical role R&D testing has for breeders, cultivators, and of course for manufacturers developing new products. We welcome working with our clients so our technology can support a product’s expedited time-to-market. Combining vision with data is transparent science.
