After all, testing laboratories are gateways within the supply chain to move your product to market. We offer R&D and compliance testing, so you have both insight into your product, and valuable data to inform your cultivation and manufacturing decisions. We understand that methodologies and machine names can be daunting and unfamiliar. Our team is here to answer any questions you may have, and even review COAs from other labs with you. We invite you to join us on a virtual tour of Sonoma Lab Works. Take a look at our equipment and learn about our different tests and methodologies.

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.
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).
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.
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).
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.
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 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.
We are proud to work with Medicinal Genomics to offer StrainSEEK™ advanced testing of cannabis plants. Expanded Genetics Testing available with youPCR™.
