HPLC purity + Δ⁹-THC attestation + 16-cannabinoid scan. The compliance receipt.
Purity + THC + USP <467> residual solvents + ICP-MS heavy metals. The broker / carrier COA.
Plus 66-analyte pesticide + mycotoxin panels. The 2018 Farm Bill compliance package.
Isolate is single-cannabinoid CBD at ≥ 99 % HPLC purity — crystalline material with minimal minor cannabinoids or terpenes. Distillate (sometimes called 'broad spectrum' or 'full spectrum') has CBD as the major component but retains a measurable fraction of minor cannabinoids (CBG, CBN, CBC, occasionally Δ⁹-THC). The 16-cannabinoid scan confirms which product is in the vial: isolate shows < 0.5 % combined minor cannabinoids; distillate shows 5-20 %.
Per the 2018 Farm Bill, total THC = `(THCA × 0.877) + Δ⁹-THC`, where the 0.877 factor accounts for the mass loss when THCA decarboxylates to Δ⁹-THC. The result is reported as % dry weight against the 0.3 % ceiling. For true isolate, both THCA and Δ⁹-THC should be at or near detection limit — total THC effectively zero. Signed analyst attestation is included on every COA for broker / carrier / transport audit purposes.
Crystalline isolate: 1 g (one retail unit). Liquid distillate: 5 g. Capsules: 10 capsules. Ship at ambient temperature; CBD is stable at room temperature for the analysis window. Include lot and batch labeling on the original packaging — chain of custody starts with the seal-integrity check at sample receipt.
Yes — that's the Retail Ready ($329) panel use case. The signed Δ⁹-THC attestation is the document carriers and brokers ask for. We include explicit language tying the result to the 2018 Farm Bill compliance line plus the analyst's signature.
Yes — USP <467> covers butane (Class 2, 5000 ppm limit), hexane (Class 2, 290 ppm limit), and the full residual-solvent panel. GC-MS headspace method with isotope-labeled internal standards for accurate quantification at sub-ppm sensitivity.
Our Retail Ready panel at $329 covers HPLC + 16-cannabinoid + Δ⁹-THC + USP <467> residual solvents + ICP-MS heavy metals on a single COA. Equivalent scope at competing labs (Eurofins, ProVerde, ACS Laboratory) typically runs $425-$595. Where we differ is the published Δ⁹-THC compliance attestation — most labs report Δ⁹-THC as a number but don't add the explicit Farm Bill compliance language brokers want.
Full CBD menu — broad / full-spectrum testing, cannabinoid profile, pesticide / mycotoxin.
Kratom alkaloid quantification — botanical sibling category with similar Farm Bill / AKA-GMP dynamics.
Once CBD isolate goes into a finished supplement (gummies, capsules), label-claim verification kicks in.
