FREQUENTLY ASKED QUESTIONS
Sonoma Lab Works offers a wide range of services from potency analysis, contaminant detection, to supply chain consulting to ensure accuracy and compliance.
Located in the heart of Sonoma County, we offer quick turn-around times and unparalleled customer service.
• We employ high- pressure liquid chromatography (HPLC-PDA) for routine cannabinoid analysis.
• Gas chromatography in conjunction with both a mass spectrometer (GCMS) and a flame ionization detector (GC-FID) is used to separate and identify volatile compounds such as terpenes and residual solvents.
• Microbial contaminants are efficiently and accurately screened using quantitative polymerase-chain reaction (qPCR).
• Pesticide residues are examined by both liquid chromatography, triple quadrupole mass spectrometry (LCMS/MS) and gas chromatography, triple quadrupole mass spectrometry (GCMS/MS).
Our current turnaround time for Phase II and III compliance testing is five business days and between three to five days for R&D (depending on tests needed).
Sampling procedures and amounts differ per sample type and tests required, but the rule of thumb is one gram per test.
Cannabinoid potency, residual solvent, microbial count, filth/foreign material, pesticide analysis, moisture content, water activity, mycotoxin, heavy metals, and terpene profile (if label claimed).
A fee equal to 50% of your total test costs is added to rush testing. R&D samples may be delivered to the lab. This rush can be applied to CA compliance packages, which entail scheduling a rush pickup. Prior day notice and approval required. Samples must reach the lab by 1pm the day before the results are expected. Failure at any point during the rush process will require retesting of samples, thus negating the ability to meet the next day turnaround time. Rush fee cannot be refunded in this instance.

Compliance panels require a lab technician to procure the sample from a quarantined batch at a licensed distributor or microbusiness. R&D samples may be delivered directly to our lab during business hours or a pickup can be scheduled with us. Contact us for any scheduling needs.
We have a client portal where we will upload all of your test reports ensuring ease of access.
