Terpene profiling
Forty-two terpenes by headspace GC-MS, each quantified against a reference standard rather than estimated by area percent. The certificate lists every analyte with its own number, the total, and the three that dominate the profile.

Sample requirements and shipping
| Item | Requirement |
|---|---|
| Flower | Requirement3 g sealed, as fresh as possible |
| Concentrate or rosin | Requirement1 g in a sealed container |
| Distillate or vape cart | Requirement1 cart or 1 g |
| Condition | RequirementShip cool where you can. Terpenes are volatile; a sample left warm in transit reads low. |
Confirm the scope and quote before shipping. Shipping instructions follow the agreed testing order. We accept no walk-in drop-off, and we hold no DEA registration, so no Schedule I to V material.
Why the method matters
Area percent is not quantitation. Each terpene responds differently on a detector, so a profile built from relative areas overstates some analytes and understates others. Every number we report is against a reference standard for that compound.
Headspace sampling avoids the solvent peak that buries the light monoterpenes in a direct injection, which is why pinene and myrcene figures from a headspace method are usually higher and more honest.
What comes back
A public certificate
Every result, the method, the instrument ID, the LOD and LOQ and the signature, verifiable by accession number with no login.
The filmed route
Your package opened on camera, a photograph of each container, and the footage retained for three years. Released to you on request.
A retained sample
Held 90 days, so any result can be rechecked by us or by an accredited laboratory of your choosing.
Questions about terpene profiling
Why is my terpene total lower than another laboratory reported?
Most often because the other result was area percent rather than quantitation, or because the sample lost volatiles in transit. Ask for their method; ours prints on the certificate.
Can you add terpenes outside your list of 42?
Yes if a certified reference standard exists for the compound. Tell us the analyte and we confirm before you ship.
Do you test terpenes in a finished vape?
Yes. Send one cart and we report mg/g and the profile, alongside potency if you add it.
How should I ship to preserve the profile?
Sealed, full container with minimal headspace, and cool if the route is hot. We photograph the container on arrival so you can see the condition it reached us in.
