Headspace GC-MS testing for residual extraction solvents in hemp crude extract, distillate, isolate, and infused products. Detect ethanol, butane, propane, heptane, and more.
Every solvent-based hemp extraction process leaves residual solvent. The amount and type depends on processing conditions and purification steps.
Ethanol extraction is common but requires thorough evaporation. Residual ethanol above limits can affect product stability and safety.
Butane, propane, and pentane BHO/PHO processes require diligent purging and testing to ensure consumer safety.
Most state cannabis and hemp programs have residual solvent limits. Our method covers all common state-required analytes.
Major hemp retailers and white-label buyers increasingly require solvent COAs alongside potency and pesticide results.
Comprehensive coverage for all common hemp extraction solvents.
Submitting takes less than 5 minutes. Most projects turn around in 5–10 business days from sample receipt.
Fill out our sample intake form — sample type, quantity, and timeline. We confirm turnaround and quote within one business day.
We'll send submission instructions and our San Diego shipping address. Most samples ship ambient or cold depending on stability requirements.
Results are delivered as a signed PDF COA within the agreed turnaround. Rush service (2–3 business days) available for urgent timelines.
Ethanol is by far the most common residual solvent in hemp distillate and isolate. Hydrocarbon extractors may have butane or propane. Heptane is common in winterization steps.
Our panel covers all solvents required by California, Colorado, Oregon, and most other state cannabis/hemp programs. Contact us if your state has specific requirements.
We test CBD hemp extract. If your material is high-THC cannabis, please contact us to discuss testing options.
