Concentration effects in botanical extraction can increase pesticide levels relative to raw material. Multi-residue testing for extracts, tinctures, and concentrates with EU MRL reporting.
Concentration factors of 5–50x in botanical extraction mean that trace pesticide levels in raw material can become significant in the extract.
A 10:1 extract means pesticides are concentrated 10x. What was below limits in raw material may exceed limits in the extract.
We test ethanol extracts, CO2 extracts, glycerites, and water extracts using matrix-matched calibration.
EU organic certification requires pesticide testing against EU MRLs, which are typically much stricter than US limits.
Whole Foods, Sprouts, and natural channel retailers increasingly require pesticide COAs for botanical extracts.
One submission for comprehensive multi-residue screening.
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.
Ideally both. Raw herb testing identifies supply chain issues. Finished extract testing is required for product COA purposes and accounts for concentration effects.
Yes. Our method handles CO2 extracts, ethanol extracts, and glycerites. CO2 extracts require specific sample prep to ensure accurate recovery.
Glyphosate requires a separate LC-MS/MS method (not headspace or reversed-phase). It's available as an add-on to the standard pesticide panel.
Submit your samples and receive an ISO 17025 accreditation pending Certificate of Analysis. Results in 5–10 business days.
